Hi, I'm trying to use the same port pin as a digital in and out. however as soon as I set the port to give an output it resets back to an input on the next instruction, do I need to use soms ASM code to reset the pin to an output for a duration , then use ASM again to reset to an input?
if so can ...

Hi Ben

Many Thanks for that, I will try a larger device.

Hi Ben,

Many thanks for that.

That worked for the OSCCAL and GPIO OK but now get this :-
Launching the compiler...

Hi Ben,

Have setup the HI-TECH compiler and now get error message

Hi I have just updated my Flowcode V4 and have selected a PIC10F200, came to compile to hex and got report that, boostc/include PIC10F200 file missing,
will please direct me to a download of the PIC10F include files.

Many Thanks

Hi Guys, Well it seems as if the 16F1827 is the way to go with this, there will be a lot of redundant menory bu what the heck, Also when I tried to use the 16F1826 with 1 PWM it would not compile as it did not recconise, the ccp2 commands.
what is the work round for this?

many thanks to all

Hi Ben,
Attached is the file i'm trying to compile, it seems as if it is ccp2 that is not reconised

regards

Hi Ben,
Well I found a typo in the compiler Parameters, have corrected it and now get
(908) Exit status = 1
when I try to compile. any ideas.
many thanks

Hi I'm trying to compile to a PIC16F1826 with a bit of code writen for a 16f 818, have installed the compiler but get the message
(902) no chip name specified; use "PICC--CHIPINFO" to see availble chip names.

What am I not doingcorrectly?

Hi, Got a small problem in that the Vcc of my PIC is unstable so I need to use an external Reference voltage for my ADC ( this a battery powered circuit)
so how do I set up my ADC to use Vref+ on AN3, I am assuming that it will have to be done with a "C" statement. The PIC is a 18F819 and only AN0 ...

Hi Ben,
I hope the attachment is ok as I an not used to this froum. As I said all works well in simlation but not in hardware. I had tried to use port c for the display
and noticed that leds connected to bort b (bits 2 & 3 ) were misbehaving too wilst in simulation.

I have a problem in that the port C on a PIC18F2420 can't be controled! all works in simulation however once the program is compiled port C seems to be switched to all output's set to low, port A & B are OK (in and outputs on port A OK, LCD connected to port B is also OK) I have tried to set port C ...

Hi,
I have a major problem in that I cannot get a PIC18F1220 to run even a simple program, I have set the osccon to 0x62 which is supposed to select theinternal osc and run at 4mHz, disabled the watchdog and LVP, but can't get any joy. I have tried with 5 chips but get the same non result. Is there ...
