Posted on June 15, 2010 at 11:27Dear forum members,
I need to implement on a st7 mcu a simple and very slow half duplex rs232 like protocol(software emulated).
I have only the following resources available:
1 16bit timer.
1 output pin for the tx (a general purpose pin without output compare)
1 input pin for the rx(a general purpose pin without input capture but with external interrupt)
My question is: Is it possible to use the external interrupt functionality instead of the input capture
functionality for the reception ?
b.r.
Spectre
