firmware and help with Si4010 / Si4355 combination from Silicone Labs

Hi I am experienced embedded system developer with more than 9 years of experience. I can do it for you. I have worked on a number of Silicon Lab MCUs. please get in touch to discus it further Regards

Dear Sir, Really Glad to see your JOB posting. Believe me I have worked on Si4010 (RF + MCU) 10/14 PIN Chip along with Si4335 (receiver) recently. I developed home sensors for leak detection in kicthens/baths which are locked as people relocate for holidays. The receiver was a Si4335 based receiver IC. Si4010 is a 433/868/915MHz 8051 based MCU that can be used to transmit wireless data (KeyFob) along with in-built battery status and temperature. I luckily have the required hardware and development tools (Si C2 debugger) for flash programming. I can send you fully functional and tested code for development. I am online and available for discussion. Even if you find me off-line just drop me a message (I am GMT+5) Regards Ch

We are a team of Electrical and Electronics engineers and we are Excellent in the following areas: • Embedded C Programming. • VHDL/Verilog • Microcontroller like Arduino, Raspberry Pi, FPGA, AVR, PIC and STM32. • IDEs like Keil MDK V5, ATmel studio and MPLab XC8. • PLCs / SCADA • PCB Designing-Proteus, Eagle. • IOT Technologies like Ethernet, GSM GPRS. • HTTP Restful APIs connection for IOT Communications. Also we have good command over report writing, I can show you many samples of our previous reports. Kindly consider us for your project and text me so that we can further discuss specifically about your project's main goals and requirements. We can deliver your project efficiently at a time. If you choose me, I think you won't regret. Best Regards.

Hi, I can help you this project, i have been working with a similar system for last couple of months, we used LoRa. I do have a few questions about the scope of the project. Let's have a chat & see where it goes.\ Thanks, Harpreet

I'm an electronic engineer with more than 15 years of work experience. I work as HW designer; FW and SW developer. As HW designer, I work in Altium, KiCad and Orcad and I have experience in development single MCU (Microchip PIC and ARM Cortex) boards with several digital I/O (GPIO, UART, SPI, I2C, PWM,....) and some analog I/O. I design complete board: power section, MCU section, peripheral section,.... I design also boards with battery power; so I have experience in low power PCB design. I have also experience in commercial boards (Arduino, Raspberry, Beaglebone,...) shields design. I have also experience in bluetooth (both 2.0 and 4.0) PCB design. As FW developer, usually I work in C for Microchip PIC (MPLAB X + XC compilers) and Eclipse + GNU ARM for different ARM Cortex M3/M4 manufacturers (STM32Fx, NXP, EFM32 SiLabs, but I'm ready to learn new frameworks). I work both single task and multi task environment (FreeRTOS and RTX). I write code both for low level driver (GPIO, UART, SPI, I2C, PWM....) management, for high level/final application, for bootloader and for OTA. I work also in "C code" commercial boards Arduino/ESP32/ESP8266 and Linux embedded commercial boards (Raspberry and Beaglebone). I have also experience in bluetooth (both 2.0 and 4.0) programming. As SW developer, I work in C, C++, .NET, Java, and lot of others programming languages. Mainly I work for Windows O.S., but I have experience in Linux development too.
