receive data using software pwm for 16F639??
PostPosted: Tue Nov 27, 2007 6:36 pm     Reply with quote
As 16F639 doesn't have ccp port, i need to create software pwm to receive data sent by transmiter. Is it possible i just use a "high-low" to receive the data or timer usage is a must??
or is there another method to create software pwm??
thanks

Why do you need PWM output from the PIC to "receive" the data
from the transmitter ?

actually, i am using 18F2680 to transmit RF data..my 16F639 is used to detect the RF data.. i need to verify whether the data received is accurate or not..
or is there any other way to detect the data besides using software pwm??
or am i totally wrong from the beginning??
