I need someone to write embedded code in a Microchip PIC16F15243. The design includes a MEMS accelerometer and magnetometer that communicates with the uC vis I2C. The uC will need to process the signals from the accelerometer and magnetometer. The processing is relatively simple, a threshold above the baseline level. The device will operate on AA batteries so the uC and sensors will need to go in and out of sleep mode.

I'll design the block diagram for the I2C led project

I need a solution to drive up to 16 LEDs with PWM LED Driver (must be able to fade/blink/etc...) that communicates by I2C. I also need to read 8 ADC values, but it can be either through a multiplexer (I2C or standard) or some multi-channel ADC chip communicating by I2C. I need parts that are available right now and there should exist some development board with that chip that I can buy. The project goal is to find the parts and provide a circuit diagram of the solution (block diagram or full schematics). I am also open to alternate solutions which achieve the same purpose (driving LEDs and reading ADC using as few MCU pins as possible).

NOTE: tight deadline Goal is to develop a prototype application for STM32 that can run LUA 5.4.4 scripts. Mandatory conditions are: - targets STM32L552 (nucleo board existing for that MCU, link to active stock given down below), however one can check on an other MCU as long as project is delivered to correct target. - STM32CubeIDE based project, latest L5 SDK - must run in an freertos task - must run some simple commands and call a custom C function. Custom C function will just blink a led. - no elua or simpler project. This must be the official LUA source code running. This is not meant to be a real application, just a working proof of concept. To be valid, the program must be run successfully on a nucleo L552 board i have. Compilable project will have to be given fo...
