Re: ADC using PIC16F877A
I am pretty new to programming and I may be way off base on this one. I have a simular problem, but mine gets stuck in a calculation. The way I figured it out is I commented out one line of code at a time and reloaded it. When everything else in the program worked...
I am having trouble selecting the clock freq using the OSCCON register.
The uC seems to be stuck at 4 Mhz for some reason. I have tried setting the scs bit and changing IRCF <2:0> to varies thing but the highest freq I can get is 500 kHz. I have tried it in several different places in my...
I found this... **broken link removed**
Basically, you need to change your pulse to an analog signal, you can then send this to a uC and with the use of timers and some code convert this to your desired outcome. When converting your pulse pay attention to the output voltage that will go to...
Ok, helpful but I assume you want to store this on said device and retreive the info later? Also, I am assuming you are trying to detect the sppen at which your taxies are going? Or does this pulse only happen at every x distance? Therefore you want the total distance traveled for his/her route.
Why not just parallel them across the supply voltage and put each one one a current limiting resistor? You will have to take note of the high power rating of each resistor. Can you post a schematic of what your trying to do?
