Primitive PS/2 Library for AVR | |||||
============================== | |||||
Host side is only supported now. | |||||
Synchronous USART is used to receive data by hardware process | |||||
rather than interrupt. During V-USB interrupt runs, CLOCK interrupt | |||||
cannot interpose. In the result it is prone to lost CLOCK edge. | |||||
I/O control | |||||
----------- | |||||
High state is asserted by internal pull-up. | |||||
If you have a signaling problem, you may need to have | |||||
external pull-up resisters on CLOCK and DATA line. | |||||

General Description: | |||||
This module implements a function for debug logs on the serial line of the | |||||
AVR microcontroller. Debugging can be configured with the define | |||||
'DEBUG_LEVEL'. If this macro is not defined or defined to 0, all debugging | |||||
calls are no-ops. If it is 1, DBG1 logs will appear, but not DBG2. If it is | |||||
2, DBG1 and DBG2 logs will be printed. | |||||
A debug log consists of a label ('prefix') to indicate which debug log created | |||||
the output and a memory block to dump in hex ('data' and 'len'). | |||||
