arduino uno (or any atmega328p for this example) and adxl345 - Klipper0.10.0

Steps

1. Get arduino uno (or any atmega328p for this example) and adxl345
2. run make menu config and setup for your crystal speed (usually 16mhz) and atmega 328p
3. make
4. avrdude -carduino -patmega328p -P/dev/ttyUSB0 -b115200 -D -Uflash:w:out/klipper.elf.hex:i
5. get mcu port from KIAUH, example : "/dev/serial/usb-1a86_USB2.0-Ser_-if00-port0" and add new MCU with new port to print config
6. add info about new accelerometer to config
7. test in console with ACCELEROMETER_QUERY

TroubleShooting

If your Arduino klipper firmware wont compile check here if your using ubuntu and cannot find your MCU path try -b250000 (or a slower baud rate) if you are out of sync and get stk500 errors when using avrdude.
