Hi anyone
1-I want to know how I can determine sampling time for pic16f877’s onchip A/D with picbasic pro?
2-How I can read data from on chip A/D in pic16f877 and save them to micro’s RAM with pic basic pro compiler?
Any suggestions would be helpful.
3-I want to use 8 bits A/D instead of 10 bits in pic16f877.
I use from pic basic pro as compiler.
Thank you very much.
The average sampling time is 50uS although this will depend on the capacitance of the external circuitry you are sampling. I refer you to the ADC chapter in your PIC's Datasheet.
Also please do a search on this forum - there are plenty of examples already posted (including a complete program to read six ADC's and Datalogging the results, that I posted less than two weeks ago). Reading about the ADCIN command in your PBP manual is also a good place to start...
