My board does not work with this library

[techpaul]

When your board does not work with Library

1. Check Wiring
2. Check assignment of pins in software and board match
3. Are you using a USB keyboard through PS2 adapter ?

• IF so get a native PS2 keyboard as USB keyboards draw too much current often with external power on your board causing MCU and/or keyboard resets

4. Has your board been tested to work with keyboard check the Readme file see Readme.md
5. Have you turned on ALL compiler warnings as shown in the Readme file see Readme.md
6. If when sending data to the Keyboard (e.g. LEDs) the application locks up, you have an interrupt issue try using PS2_CLEAR_PENDING_IRQ in PS2KeyAdvanced.h for your board/architecture

If you are sure your board has been tested ask questions here.

If your board has NOT been tested you may want to check how to add your own support and need to do various interrupt tests by sending commands to the keyboard like LEDs, see Porting.md
