Is there a C gpio library for Beagleplay?

General Discussion
1

I am doing SPI driver on Beagleplay with device Accelerometer, ADXL-345.

2

Why? Is this for a class project?

There are two drivers for the ADXL-345 already in the linux kernel. The older under input/misc and the newer IIO variant. Plus all the python user-space examples. adxl345_core.c « accel « iio « drivers - kernel/git/torvalds/linux.git - Linux kernel source tree

I am amazed at the above question.
But I am doing it on my own. Any suggestions for encouragement?

Python: GitHub - adafruit/Adafruit_CircuitPython_ADXL34x: A CircuitPython driver for the ADXL34x family of accelerometers
C: GitHub - libdriver/adxl345: ADXL345 full function driver library for general MCU and Linux.

NodeJS: GitHub - skylarstein/adxl345-sensor: A Node.js I2C module for the Analog Devices ADXL345 three-axis digital accelerometer

The ADXL345 has had a ton of driver examples written over the years…

We don’t use a “driver” its all ioctl using c++, much easier to work with. You can do stuff in c but if you must take your work to the next level learn c++.

thanks.
