Dear Client,
I hope this proposal finds you well. I am thrilled to submit my bid for the project you have posted. As an experienced software engineer with a strong focus on C Programming and Electronics development, I am confident in my ability to deliver exceptional results.
I understand that you are looking to convert your current commercial system, which runs on the dsPIC33EP512GP506, to the ESP32S3 microcontroller. I have extensive experience in microcontroller programming, PCB layout, and electrical engineering, which makes me the perfect candidate for this project.
To successfully complete this project, I propose the following milestones:
1) Redesign the current circuit board to be exactly the same size, same plugs, same mounting holes, and peripherals, but with the ESP32S3 microcontroller. This will require creating new schematic and gerber files.
2) Migrate the existing C code, especially the device drivers, to run efficiently on the ESP32S3. I will ensure that the software timers work at the same speed as the current ones.
3) Build in support for ESP NOW RF, specifically the ESP NOW 4 protocol, to take advantage of its capabilities for future development.
4) Build 20 prototype boards with all components to fully prove the design. I will provide two sets of peripherals, including 4 x 16 character LCD, CC1101SE RF 433MHz module, speaker, TX infrared on a PCB with 3 color LED outputs, RX infrared (Gun), RX infrared (Head) with 2 colored LED outputs, SD card, and key switch on/off.
I would like to discuss the project requirements more carefully with you. Kindly connect with me in the chat so that we can have a detailed conversation.
Thank you for considering my bid. I look forward to the opportunity to work with you and deliver exceptional results for your project.
Best regards,
