Introduction

The purpose of this project is to fetch data from sensors on the PCB, convert it into CAN format, and send it to the flight computer. This document will record the details and progress of each sensor.

Progress

• Setup basic I2C transceive function(in blocking mode)

• Setup functions for each command(refer to data sheet 15.1)

• Setup functions to manipulate register values and data conversion(refer to data sheet 16) - in progress

Notes

• Consideration of DMA

• Conversion setting: Higher OSR and digital filter setting lead to higher accuracy and lower noise, but increase in covnersion time(refer to datasheet 16.2.5)

• Sensitivity setting: Gain and resolution need to be tested on breakout board(refer to datasheet 16.2.4)
