Works great, printed and used on THE 100 v1.1

I can’t get the adxl345 working with the bpi, SPI just won’t work on that board :(
I would suggest for anyone thinking of using an adxl345 on their the100, go for a USB version
@JazzyJustin_789465 Had, same issue, but there is a solution. Add to /boot/armbianEnv.txt this lines
param_spidev_spi_bus=0
param_spidev_max_freq=100000000
and reboot.
P.S. I've also enabled spi-spidev in hardware settings. Not sure if it's needed. (edited)
