PostForum: General CCS C Discussion   Posted: Wed Jun 14, 2017 8:37 am   Subject: Interfacing PIC to removable memory
I'm using a PIC16F1789.

I'd like to have some type of removal memory storage interfaced with the pic. The type of memory device is not important, as long as I can easily remove it and connect it t ...

With Alternate Pin Functions you typically get a choice of two pre-defined
pins for a peripheral function. You have to choose one pin or the other.
Example, for CCP1 output, you get to pick Pin B0 ...

The 16F1784 does not have Pin Select. It has Alternate Pin Functions.

Thanks. I'm not sure I understand the difference between pin select/alternate pin functions. Is this saying ccp1 can be used ...

PostForum: General CCS C Discussion   Posted: Sun Oct 16, 2016 3:54 pm   Subject: PWM on ccp1 - no output [SOLVED]
first line of code HAS to be the #include PICtype header
2nd line would be 'fuses'...

3rd thing is to disable ALL other peripherals that use the pin
4th does that PIC have 'pin select' ( I don' ...

Your first post had ANSEL0 (zero); now changed to ANSELD (Delta).

No.

I write to both ANCON0, and ANSELD......

I'm almost ready to believe that you're just trolling me? Rolling Eyes

You are typing something wrong.

I tested the code as posted on your compiler version:

#byte ANSELD=getenv("SFR:ANSELD")

void main()
{
ANSELD=0;

Can confirm it does not configure the ADC for Vref:

#byte ADCON0=getenv("SFR:ADCON0")
#byte ANSEL0=getenv("SFR:ANSEL0")

Guy is spot on here.

As you change speeds, the CPU power consumption changes, but the peripheral consumption remains the same.
Now when you talk about 'displaying the data on an LCD'. What sort o ...

This PIC has 3 internal oscillators: 16 MHz, 500 kHz, 31 kHz
Take a look at page 68 in the datasheet - there are many frequency options in between. These are only actual oscillators.

Ah, didn't s ...

You might want to 'do the math' or actual board level testing of slow clock speed vs fast clock speed with sleep mode.

While the faster clock ( 500* faster) does consume more current, since operati ...

I have to ask WHY are you tunning the PIC so sloooooooooooow ??
All operations, especially the floating point math will take forever..

Not seeing what else you do in the program but over the past ...

It absolutely must be as shown below, for it to work:

Also, this is how the 16F1784. ...
