16F84 Port A
Posted: Fri Jan 23, 2009 12:59 am
Hi
Can I just ask you to clear something up ...
I am teaching PIc programming for the 16F84 using your E-blocks mutliprogrammer development board, and associated e-block led and switch modules.
I realise that PortA RA4 on the 16F84 is dual purpose and can be used as an output of used with an external oscillator.
I wish to use it as an output to drive an led. I can't see anywhere if flowcode where I can set the relevant config bits to select this function.
Will I be able to use it if I set the relevant config bit in the assembler code instead of trying it in flowcode?
As I am using this for software teaching purposes, we won't be building our own circuits so I was hoping to use the development board 100% of the time. It will be disappointing if I can never let students use the full output capability of PortA.
Is RA4 actually connected to the corresponding led on the led module?
Is there a hardware modification which can be made to route RA4 to the fifth led on the led module?
Thanks in advance
