Using the libary with a SC7A20 Accelerometer

[gadjet]

Subject of the issue

I have used the libray to access a SC7A20 accelorometer but all of a sudden it fails to connect to the device and I can't figure out what's changed, it was working fine

Your workbench

• I'm using an ESP32 C3 WROOM moddule on a custom PCB
• The device is connected via the I2C connections and there are 4k7 pull-ups installed
• The PCB is being powered from the USB programming supply via an LDO 3.3V regulator
• Using modifed versions of the examples I add #define LIS2DH12_ID = 0x11U; into the sketch to overide the standard chip ID of 0x33U as the SC7A20 has a different ID of 0x11U.

Steps to reproduce

Press reset or power up

Expected behavior

The serial console streams accelerometer data form the ESP32 via the USB connection (DCD on boot enabled). It has successfully done this for a few hours bfore suddenly failing to connect and never workiing again

Actual behavior

I just gives the "Accelerometer not detected. Are you sure you did a Wire.begin()? Freezing..." error

I have used a logic analyser to see what the I2C messages are doing and that looks to be good

Futher information: - I removed the #define LIS2DH12_ID = 0x11 from the sketch and edited the LIS2DH_reg.h file and changed LIS2DH12_ID = 0x33U to LIS2DH12_ID = 0x11U and it works now.

Why would local #define statement not override the LIS2DH_reg.h file?
