esp32-logger

Log output from ICM_20948 and H3LIS331DL

Hacks

Not my fault; it's library stuff and icb forking.

SparkFun ICM

• NOTE; have to enable DMP firmware loading in SparkFun's lib:
• => Uncomment line 29: #define ICM_20948_USE_DMP (ICM_20948_C.h)

SparkFun LIS

• Also, sparkfun's LIS library conflicts with esp32 hal
• change identifier "OPEN_DRAIN" -> "OPEN_DRAIN_LIS" (or whatever)

Notes

• ESP32 has VSPI and HSPI - pins for both interfaces can be matrixed to whichever pins you want
• the default SPI class in the SPI library is bound to the HSPI interface
• SparkFun's LIS library doesn't allow using a custom SPIClass - so I'm forced to bind it to HSPI bus
• LIS module + SD 2 share HSPI bus
• ICM module uses I2C
• ICM SD uses FSPI bus
