There is something rather odd about test mode though. If the RED LED is OFF you will receive up to 6 keypresses in the "Key Test" reponse. However, if the RED LED is ON and you press and hold one key and then press and hold another key you'll get a "Key Test" event with no key press information. Thus, you'll never be able to check for more than one key pressed at a time when in "Test" mode and the RED LED is ON. Weird. |
