Altitude Estimation with Pressure Sensors (STM32, Firmware + Hardware) - Phil's Lab #68
Estimating altitude (relative) with pressure measurements via a barometric pressure sensor. All the way from theory with equations, to implementation on custom hardware and custom firmware written for an STM32 microcontroller. Utilizing an I2C/SPI-based absolute pressure sensor (SPL06-001), showing how the driver code was written. Including basics on simple digital IIR low-pass filters.
