The first thing is as soon as you put a scope on to test, the frequency _will_ shift. Not a lot, but a detectable amount. You need to be testing the OSC2 pin. This is the output from the PIC, while OS ...

Hello,
I am using Pic12f1840 with a 4MHZ external crystal oscillator ( ABLSG-4.000MHZ-D-2-Y-T) with a 22pF load caps. I am getting 1.2v peak-peak voltage.
2 questions:

Is the peak-peak voltage no ...

I got it working now. It turns out that even though the Vref- and Vref+ in ADCON1 are setup by default to '0' once I explicitly made them '0' I started getting the right result.

I never thought thi ...

what IS IT that are you trying to DO with the ADC that is not bundled already into the very simple , but elegant CCS intrinsics for ADC operation?

you are exerting immense effort in reinventing a ...

Hello All,

I am having trouble getting the A2D to work on PIC16f1939. I am using CCS compiler 5.007.
The built in A2D function works fine but when I follow the manual method( more control) I cou ...

Problem fixed, it was a programer issue. Thanks !

Thanks for the reply, see my answers below.

first observations would be

1) *MCLR tied high ? or disabled ??
MCLR set as input. So it's disabled

2) GP1 is used for programming, is it 're ...

Hello,

I am trying to get a simple code running on a PIC10f204 to flash an LED. This is always my first step to make sure the GPIO pins are functioning properly. I wrote this code and unfortunatel ...

The CCS load-n-go fits the bill. Sell one to the customer and have them install the CCSload program on their PC. Then just email them the hex file. They start up CCSload, download the program to th ...

Hello,

I am working on a small handheld device that uses a pic16f1939 and would like to know how to allow customers to perform a firmware update on this device?

From what I read, I could use a u ...

Hello,

Ever since I migrated from the Pic16f727 to the Pic16f1939 I started having problems with the capsense sensitivity. The capsense module won't detect a finger press with an overlay anymore. I ...

Thank you for the reply, "however I do" was a typo.

The problem was I was using #include <flex_lcd.c> instead of
#include "flex_lcd.c"
The carrot worked fine with the ...

Hello,

I have used the flex lcd driver provided here:

Thank you for the code ! I will test it out and let you how it works.
