Once again, thank you for considering me. Hiring my services means guaranteeing yourself not just expertise but an unwavering dedication to ensuring project success!

@maxscender

I’ll write a compact SDD1333 driver in C that initializes the display over the given I2C pins (SDA RB4, SCL RB6), handles the RES# line on RB7, and targets slave address 0x3C. The code will include low-level drawing primitives for lines and filled/outlined shapes, then build a number-rendering function on top of those primitives so values 0–140 are drawn as clean, centered 50x50 pixel digits in white. I’ll structure it so the existing main.c wiring test can be reused with minimal changes, and the driver will expose simple, practical calls such as ssd1333_line(), ssd1333_rect(), and ssd1333_number() for direct use.

@mayr81

I can develop C firmware for the SSD1333 display driver targeting the provided wiring (SDA RB4, SCL RB6, RES# RB7, Slave ADDR 0x3C). I’ll deliver basic initialization plus graphic primitives for lines and shapes, then build a centered rendering path to draw numerals by mapping values into 50×50 pixel blocks (starting with 0-140, ~50×50 each). Using your test main.c as the baseline, I’ll verify bus transactions, controller setup, and implement efficient draw routines (windowing/coordinate addressing) so numbers and geometric shapes render cleanly in white (or an easy color toggle if the panel supports it). Deliverables: optimized C driver (init, set-addr window, drawPixel/line/rect, and digit/number render function), integration with the existing main.c, and a small demo that iterates 0-140 in sequence.

@starttechno

For your SSD1333 176x176 RGB OLED, I will develop a clean C driver for the PIC16F17126 using the wiring you provided: SDA on RB4, SCL on RB6, RES# on RB7, and I2C address 0x3C. The driver will include initialization, reset timing, command/data transmission, display clearing, address-window handling, pixel and color support, plus graphic primitives for lines, rectangles, and filled shapes. I will also add a simple API such as SSD1333_DisplayNumber(uint16_t value), rendering values 0–140 in a centered, readable font with a practical display area rather than blindly forcing 50x50 pixels. The implementation will follow the datasheet’s I2C control-byte format and GDDRAM mapping on pages 15–20, including the required power-up/reset sequence from page 26. White can be the default color, while retaining RGB color parameters for future use. The attached main.c will be reviewed and integrated rather than replaced unnecessarily. I will provide organized .c/.h files, font data, usage examples, and a test routine that cycles through 0–140 and exercises lines and shapes. My closest embedded example is a Raspberry Pi + PlutoSDR kiosk, where I worked across hardware-facing software and device integration; I also bring 10+ years of C/software development experience and 249+ delivered projects. Will you be able to test the delivered code on the physically wired PIC/display so I can verify the rendered output? Muhammad Saad

The control byte in front of every I2C write drives the SSD1333: 0x80 as the first byte keeps you in single command mode, drop that continuation bit and the stream free runs as commands, and 0x40 flips the same channel to GDDRAM data. Get that byte wrong and half your init sequence either gets ignored or written straight into display memory as garbage pixels. I'd wire the init the way you're already driving it, RB4/RB6 for SDA/SCL, RB7 pulsed low for RES with the datasheet's minimum reset width honoured first, then charge pump, addressing mode, contrast and display on in that order so nothing races the panel. On top of that a small primitive layer: setPixel doing the page/column math so it drops straight over your GDDRAM writes, line as a Bresenham walk over setPixel, rect as four lines or a filled scan depending on what you need. For the number routine I'd bitmap a fixed digit font, work out width and height for one to three digits, then center that block inside the 50x50 window with integer offsets so it doesn't drift pixel to pixel between values. Drops into your existing main.c without touching the wiring test you've got running. M1: init sequence and I2C control byte handling verified on your board, $215, 2 days. M2: setPixel/line/rect primitives, $215, 2 days. M3: centered number-in-box renderer for 0-140, $220, 1 day. Fixed digit size across 1 to 3 digits, or scale up for single digit values to fill more of the box?

I have experience developing embedded C firmware, microcontroller display drivers, I2C communication, graphic primitives, and low-level hardware interfaces. I can implement the SDD1333 driver with initialization, I2C communication using SDA RB4 / SCL RB6, reset on RB7, slave address 0x3C, and drawing functions for lines, rectangles, and other basic shapes. I can also create a reusable number-rendering function that accepts a value from 0–140 and displays it centered at an appropriate size, with configurable colour and dimensions. I’ll keep the driver clean, modular, and easy to extend for additional graphics or text later. I can start immediately and would be happy to review the supplied main.c wiring test and share relevant embedded/display-driver work.

@Jairo51019

I have extensive experience writing low-level C drivers for OLED displays, including the SSD1333 controller. Your project fits my expertise perfectly. Technical Approach: I2C Communication – Implement robust read/write functions using SDA (RB4), SCL (RB6), RES# (RB7), and slave address 0x3C Proper Initialization Sequence – Follow the SSD1333 power-on sequence: VDD stable → wait 20ms → RES# low for ≥3µs → RES# high Frame Buffer Management – SSD1333 has 176x176 RGB pixels with 16-bit color depth (RGB 5-6-5) Graphic Primitives – Implement Bresenham’s line algorithm, rectangle drawing, and a large digit renderer for numbers 0–140 Font Rendering – Create a 50×50 pixel custom font or scale a smaller font proportionally, centered on display Deliverables: Complete C driver with display init, I2C read/write, command/data separation Graphics library: drawLine(), drawRect(), fillRect(), drawNumber(int num) Your main.c integrated and tested with the wiring you provided Fully commented code with clear API documentation Similar Work: I've developed display drivers for SSD1306, ILI9341, and ST7735 from scratch, including custom font generators and graphic primitive libraries for embedded systems. Timeline: 5–7 days for full implementation, testing with your hardware, and delivery.

Hi, this looks like a focused SSD1333 driver task: bring up the display over I2C on the PIC16F17126 and add clean graphics primitives for centered numbers and basic shapes. I’ve worked on embedded C display drivers and graphics code, including initialization sequences, coordinate mapping, and drawing routines for small OLED/TFT modules. I’m comfortable reading datasheets and wiring notes, then turning that into reliable code that matches the controller’s expectations. My approach would be to validate the init flow first, then build a compact drawing layer for lines, rectangles, and number rendering. I’d structure the number function so you can pass a value and render it centered in a 50x50 area or another size that fits best on the SSD1333. If you’d like, I can start from your main.c and wire notes and get the first number-rendering version working quickly. Best regards, Gabriel

@mengw3

I've spent 20+ years in embedded C, mostly PIC and AVR/STM32 over I2C and SPI. I've written OLED/LCD init sequences, GDDRAM addressing, and pixel-level graphics primitives (Bresenham lines, rectangles, fills) from scratch, so a bare-metal SSD1333 driver is a normal build for me. The hard part here isn't the init sequence, it's building a digit-to-bitmap renderer that scales cleanly to an arbitrary block size and stays centered. - Bring-up: RES# low-high pulse, then the SSD1333 command block (display off, remap, contrast, display on) over RB4/RB6 I2C at address 0x3C, checked against your main.c wiring first. - Core primitives: draw_pixel, draw_line (Bresenham), draw_rect/fill_rect. Everything else builds on these. - draw_number(uint8_t value) renders 0-140 with those primitives, scaled to about 50x50 and centered, block size set as a #define so it's easy to resize. - Font starts as simple line/segment shapes (fast, small flash footprint); can swap to a bitmap font later for sharper digits. Color defaults to white, exposed as a parameter. You'll get commented .c/.h source, a short README on the pin map and resizing, tested against your wiring before I call it done. Quick question: is this a PIC (RBx naming), on XC8/MPLAB? And is I2C bit-banged or the hardware module? I can start right away.

@arturg6

Hello, "SSD1333 Graphics Driver In C" - initialize the display and add reliable number, line, and shape drawing I can build the C driver around your PIC wiring, keeping initialization and I2C command/data handling separate from drawing primitives. I’ll start with the 0–140 number renderer, then add centered lines/shapes and verify the output against your test setup. Can you confirm the exact PIC16F1 device used? Artur Gizycki

@KurtSiebritz

Let's Do This Right The First Time ✔️The key here is careful initialization of the display driver. Working with the SDD1333 requires precise handling of commands for effective graphic drawing. I understand the importance of enabling graphic drawing capabilities for lines and shapes on the SDD1333. What usually matters most here is ensuring the display can accurately render numbers, like structuring the display to handle the size and positioning of graphics. With years of experience in C programming and display drivers, I've helped bring graphic capabilities to various projects. You can expect clear, centered numbers displayed in a visually appealing manner. Based on what you mentioned, my core focus would be: • Basic display initialization • Graphic drawing capabilities • Number rendering in a defined structure If you want I could take a look at your existing files and give you some direction? Best, Kurt.

@juanestebana17

Hi! I understand you need C code for the SDD1333 display driver with basic initialization and graphic drawing for lines, shapes, and centered number rendering.

I’m ready to get started, and I’m confident we can make this project a success and deliver it to a high standard. I’m committed to ensuring everything is completed professionally, efficiently, and exactly according to your requirements. Best regards!

@HamparProd

Hi, I reviewed the supplied main.c and SSD1333 documentation rather than treating this as a generic display-driver job. There are already a few concrete issues worth correcting first. The current 32-byte fill buffer can write one byte past its boundary and sends an odd number of pixel-data bytes even though the display uses 16-bit pixels. I also noticed an ACK/debug helper using 0x33 while the configured SSD1333 address is 0x3C. I would first stabilise the existing PIC/MCC I2C and SSD1333 initialization, then build clean graphics primitives for pixels, lines and rectangles. For numbers 0–140, I would implement a reusable digit renderer rather than storing 141 images. A function can accept the numeric value, scale the digits appropriately and automatically centre the result on the 176×176 display. I will keep the driver modular and documented so additional graphics can be added later without changing the low-level I2C layer. I can start immediately after award.
