Port ESP32 ADS1299 Firmware

@macroenergy

Being an electrical engineer with experience in multiple domains, I firmly believe that I am the best fit for your project. My expertise in digital motor control, power electronics, and embedded systems aligns perfectly with your requirements of a stable firmware upgrade on the ESP32-S3-WROOM-1. I have done projects that required pin mapping, SPI handling and data structure extensions to accommodate extra functionality while ensuring continuous smooth functioning of previous features. Not only have I worked with ESP-IDF and TI ADS1299 driver as required, but I also back my credentials with hands-on knowledge in using the logic-analyser to trace hardware outputs to shorten verification time. In addition, my understanding of analog design and electronic circuitry enables me to effectively comprehend the complexities involved in managing multiple channels like you are needing. With regard to power electronics experience, I’ve dealt extensively with converters and sensing circuits. Stretching the 16 to 24 input channels comes under no challenge for me. What sets me apart is also my fluency in C programming, Matlab simulation, and proven skillset on various microcontrollers including PIC18,PIC24,PIC30 and dsPIC, Ardino, MSP430, Renesas, STM32,C2000 etc. This allows me to adapt seamlessly with the existing project codebase. Thus coming on board means guaranteeing the revised source code’s sound fitting with your sdkconfig.

I have gone through the ADC details. So it needs additional SPI chip enable signals to read the additional chips. I can make the necessary changes and update the project files. Please send me the existing code base let us discuss and finalize.

I have gone through your requirement and this aligns well with our prior experience at HardFault. We have previously worked extensively with ADS series modules for brain signal acquisition systems, including ADS interfaces with STM32 platforms for EEG/biopotential data collection, so we understand the importance of channel synchronisation, timing integrity, and clean multi-device SPI handling. Alongside this, we have strong expertise with ESP32 development, especially ESP-IDF-based firmware on ESP32 variants, including migration and bring-up work across different ESP32 modules. For your requirement, we can take the existing ESP32-WROVER-E firmware and carefully migrate it to the ESP32-S3-WROOM-1 while keeping the current architecture, libraries, and TI ADS1299 driver intact. We will extend the firmware from 2 daisy-chained ADS1299s to 5 devices (24 channels), refactor SPI handling, pin mapping, and internal data structures to support the additional converters, while ensuring all existing features . We understand that maintaining channel order, deterministic timing, and zero dropped samples is critical in EEG systems, and we will provide the updated source, reproducible sdkconfig, changelog, and verification outputs for validation.

I’ve done this exact type of port before—moving firmware between ESP32 and ADS MCUs—and I know the pitfalls that come with peripheral mapping, clock configuration, and interrupt handling on different architectures. I can get your existing logic running on the target silicon without regressions or performance loss. I work directly with the hardware, not just the SDK, so I catch timing issues early. I handle firmware, custom PCB design, and full prototype assembly in-house, which means I can own any hardware adjustments that surface during the port. For context, I recently shipped a custom ESP32 controller board for a model railway system with 24 servo-actuated track points, including a Node.js API layer, all delivered in under three weeks. If you want this done cleanly and on schedule, let’s talk specifics.

Hi, I have solid ESP32/ESP-IDF experience — SPI bus configuration, peripheral drivers, and porting firmware across ESP32 variants — which covers the core of what this migration requires. My approach: — Review the existing codebase first to fully understand the ADS1299 daisy-chain protocol, data frame structure, and SPI timing before touching anything. — Extend the pin mapping and SPI initialisation for the ESP32-S3-WROOM-1, accounting for the GPIO matrix differences from the WROVER-E. — Scale the driver's device count from 2 from 5, updating channel indexing, data packet assembly, and any DMA/interrupt logic so all 24 channels stream with correct ordering and no dropped samples. — Keep Wi-Fi, BLE, and on-board filtering untouched — changes will be strictly scoped to the SPI/ADC layer. — Deliver updated source, a clear change log, and the sdkconfig for reproducible builds. I'll be straightforward: I haven't used the ADS1299 directly before, but the porting task here is well-defined — the existing driver stays in place, and the work is structural (scaling SPI chains, data structs, pin maps). I don't have an S3 board on hand, so I'd rely on your hardware for final flash verification. Could you share the repo so I can assess the current driver structure before confirming scope? Best regards

After reviewing this project, I find it aligns perfectly with my expertise, having successfully managed similar tasks for clients in the past. The quality of my work is unparalleled. I understand the critical need for seamless integration of the ESP32-S3-WROOM-1 and the additional ADS1299s while maintaining all existing functionalities. I will ensure proper recognition, initialization, and streaming of the three new converters to match the original setup flawlessly. While new to Freelancer, I bring years of experience and offer a discounted rate to establish my profile. This project suits me as I excel in clean, professional, and integrated firmware development, meeting all specified requirements efficiently. Regards, Louis Brink

I have done similar coding works with TIs 24 bit ADCs. I can do this job easily for 5 quantities of ESP32-S3-WROOM-1 for 24 input channel acquisition
