Hello,
Ok I have been at this problem for too long and now need advice.
I have a 5vdc positive going pulse train that the frequency changes but the dutycycle stays the same. I need to either convert to a frequency dependant voltage or directly read with a microcontroller.
I have tried using...
this might be one of those obvious head-desk things, but are you clearing the counter after latching the result?
I do not know your process but the method I would use would be to clear counter, start timer 1second, on end of timer latch result and clear counter. A flip-flop on the output of the...
You could use a PIC micro controller to count the number of pulses every second and then store the result in a register for processing or output the result to a i/o port to send to another processor.
thanks for the 101 in rs232, but my question was based on protocols not the physical layer, i chose rs485 for that and can send bytes fine, just dont know how to implement a protocol for control. part of the protocol is addressing, how to make pic respond to thier address and reply.
PS i am...
Hi all,
I am designing a rs485 2 wire multi-drop network, this is for a learning/hobby project, I am having trouble creating the code in assembler, I am not up to speed in C and would like to try to stay away from basic as im still fairly new to pic controllers and want to learn assembler...
