Posted on January 04, 2007 at 07:54 Dear All,
I like MCU programming but only very strong. Since I think there must have some ST7 beginner browsing this page, I still would like to share my coding there (may be you will think the coding is too simple, haha....). Anyway, it is a assembly program, which used my favourite looping with ''call'' function''. If I understand how to use other peripherials, I will upload again. ^^
(Please suggest if my format is not good ^^)
Does anyone try to use software to finish UART(SCI)? is it hard to use assembly to achieve?
My share coding format
