hi everybody,
today i saw an odd situation. i have a circuit on which there is a receiver module with a digital output and the output is directly connected to an input pin of an mcu. i observed the digital data output of the receiver and saw normal parasitic data. but when i connect to the mcu with the debugger i see a periodic data (on the oscilloscope) on the output and when i send data via a trannsmitter it does not appear on the receiver......what is the problem?
