If we want to make communication between 7LITE and PC,

7LITE only have the SPI com method,

How can we apply UART in ST7Lite ?

The timer (8 bit in 7LITE) should can make the UART by program, right ?

Have a look at the document i have attached :

- application note descibing the procedure

- zipped files

Rem : the code has been developped for a ST72251, so you will have to change the mapfile.

For ST7LITE0 we do not have any reference available presently but will be available within month duration.

Basic Idea:

You can use 12 bit autoreload timer - output compare functionality along with 2 i/o pins, one config. in input mode with interrupt enable & other in output mode.

Interrupt will be enabled only to sense START bit.
