Problem with 16F648A

[ngeronikolos]

My friend duncan303,

Last I looked the 16F628 didn't have A/D Converters and as such doesn't have ADCON Registers - but you might want to correct me on that...

hi Nikos,

Are you on 16F628 or on the 16F648A, they are not identical the datasheets are similar but differrent, one is the A series.

No matter, I have got the 16F62X sheet open at the moment, the register associated with the PortA is listed on page 34 table 5.2, therefore you will be looking at the CMCON register, if you look in the PBP manual on page 10 it will help explain better than I can right now, just off for my Sunday roast


Mmm hungry

Hi ngeronikolos,
Please read this thread:

You will see to use internal Osc does not require you to set osc to HS, are you doing that manualy in the programmers fuse?, I ask because of your comment in define statement?
Early in your code put CMCON = 7 to disable comparators.
your statement:

'constants for RF configuration modes
CONRFRX var byte
CONRFTX var byte

these are set as variables not constants.
Call to nonexistant sub directory: GOSUB initRFConfig
What is " mpla " ?
your

 'constants to define receive/transmit modes at 2402 Mhz frequency
CONRFTX = $04
RFCurrentState = CONRFTX

If you had properly set those as constants, I do not think you could redefine them later in code, since you set them as VAR it works. to make them constants just rewrite as:

 CONRFTX CON $04

'at the beginning, then you give the variable RFCurrentState it's value as above RFCurrentState = CONRFTX .
This is your statament:
@ DEVICE pic16F648A, INTRC_OSC_NOCLKOUT ' system clock options
Change to :
@ DEVICE pic16F648A, INTOSC_OSC_NOCLKOUT ' use internal OSC instead of R/C osc
If you installed everything in the default places when you setup PBP then you should find a file called P16F648A in this directory:C:\Program Files\Microchip\MPASM Suite , open it and look at the last several lines to see all available config fuses for this chip.
