usage)
1. insert isr routine to interrupt procedure.
2. call initialize procedure after USART1_init(...).
3. set Global Interrupt enable bit.

note) You must save FSR at Interrupt routine. Mikro Compiler don't generate FSR register save/restore codes in Interrupt routine.

copy & paste codes in user main source. it's more small space than using unit source.

sorry, my English is not well.

PS2 click with interrupt

0

This program decodes the key strokes from a PS/2 keyboard, connected to a Mikroe PS/2 click module, using an external interrupt. It echoes each pressed key to the UART terminal and stores on a buffer. When the ENTER key is pressed, a line feed together with the content of the buffer are sent to the UART terminal, as a demonstration purpose.
