Testing the LIS2DW12 accelerometer in Rust
The following hardware is used:
- STM32 bluepill (an STM32F103C8T6 MCU).
- ST-LINK-V2 for programming and debug logging
- STEVAL-MKI179V1 evaluation board which exposes the the
LIS2DW12sensor
You will need probe-run which is a utility to enable cargo run to run embedded applications on a device:
cargo install probe-run
Connect the following pins for SPI:
Bluepill -> STEVAL-MKI179V1 Eval board:
A7 -> SDA (MOSI)
A6 -> SAO (MISO)
A5 -> SCL (Clock)
A4 -> CS (Chip Select)
3.3 -> VDD (3.3v power)
G -> GND (Ground)
cargo run
You should see output like this:
bla@blabla:~/source/accelerometer-test$ cargo run
