Example code or coding tips for displaying the board’s accelerometer values to the 16x2 SerLCD ?
Current components: MicroMod Machine Learning board, Artemis processor, and Sparkfun 16x2 SerLCD - RGB Backlight (Qwiic).
I can get the accelerometer values to print to the Arduino program’s serial monitor on my computer; I can get example text codes to print to the LCD, but I cannot get the two to work together. Thank you!
You just need to define a variable that they both use; something like:

This example demonstrates how to read XYZ from the LIS2DH12.
Feel like supporting open source hardware?
Buy a board from SparkFun!

Hardware Connections:
Plug a Qwiic cable into the Qwiic Accelerometer RedBoard Qwiic or BlackBoard
If you don’t have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
Open the serial monitor at 115200 baud to see the output

Should get you very close…something is wrong with Z (5 digits instead of 3?) but this get ya 90% there
