The following image is that of a Data signal, one waveform is used to represent logic level 1 and other 180 degree phase shifted waveform represents logic 0. Can someone please provide some input on how I may be able to generate the following waveforms on a micro-controller ?
5V micro?
25mA or 40mA source/sink port pins?
What is the load? (capacitance?)
Here is a guess:
You may have to tweak the resistor values a bit after you see the loaded micro port voltages. PortA can source current to the voltage divider tap; PortB can only sink current.
Dear Sir,
This image below is the signal on an Oscilloscope. The signal is generated from a Training Setup. Please let me know if any modification is required to the above circuit.
