This commit introduces support for the SC7A20 accelerometer.
The accelerometer readings can now be displayed on the screen,
and the display mode can be toggled using the encoder.
Additionally, the EMA filter constants for voltage and current
readings have been updated from K2 to K4 for potentially smoother
readings.
Setup ADC conversions to happen automatically, transferring results to a buffer
using DMA, also set up channel injection, where instead the tip temperature is
read sinchronously
Introduce `VCC_MV` to `funconfig.h` for consistent voltage readings.
Add `get_current_ma` function to `main.c` for clearer current
calculations.
Remove unused `PIN_LED` and `Delay_Ms(5000)` from `main.c`.
Update VBUS voltage calculation to use `VCC_MV`.
Print TIP sensor voltage in millivolts instead of raw ADC values.
