To measure you instruction speed use the repeat instruction

while(true)
{
#asm
repeat #0x3fff
btg .....
#endasm

}

This will give you a good burst of pin toggle at your ...

I have a strange issue using either Int external 1 or 2 in PIC24FJ64GB002.

As soon as I use #pin_select INT2/INT1=PIN_B5 the EXT1/2IF is permanently set.

Even if I try to clear the respective bi ...

Just a quick update on this issue

I noticed that when I disable the TwoSpeedStartUp fuse the processor will not run when I select the FRC with PLL as the initial oscillator in the fuses, if i enabl ...

Hi all,

I have a problem with my clock switching operation and switching on the internal PLL for the PIC24FJ64GB002.

#define switch_16mips{\ #asm \ mov #0x0743,w1\ #endasm \ #asm \ mov.b x, ...

I have used that exact chip a lot and never received any errors about Configuration bits and I use an older version of CCS.

Although I have noticed that the MCLR fuse doesn't get set correctly when ...

Hi everyone,

I have a few queries about increasing my USB transfer speed. Here is my current setup

* PIC24FJ32GB002
* Bulk
* Full Speed (Internal Pull up on D+)
* 48MHz USB sourced from 8MHz ...

I solved the problem, went into build configuration and ticked a box under options which compiles for debug.

I think another fix is to place a large dummy array in RAM at the top of main, this push ...

Hi guys,

I have a few questions about using Mplab for debug.
My setup is Mplab 8.56 and CCS4.088 and ICD3.

I use Mplab IDE and CCS compiler to compile. My PIC is 24HJ32GP302.

If I set a brea ...

Does anyone have an update on this topic?

I did some testing with the built in functions in CCS and the result returned from the CRC function which uses the hardware CRC in the PIC24HJ and the answ ...

Yes adding load capacitance seems to have helped tried lots of different combinations.
These Watch Xtals seem to need a really special PCB layout.

On my breadboard here I cant make it give an outp ...

Hi again, I am now using an external 32.768 xtal between SOSC and SOSC1 and I am seeing funny behaviour.
I have verified that the 32.768k xtal is oscillating on the SOSC pins.

When i look at the R ...

Yes you are right ! The fuse was not being set correctly and was using LPRC instead of SOSC

Thanks for the code it seems to work for me also.

Just a quick query, the RTC time seems to be way off.
I'm losing 5 seconds in ten minutes, as far as I can see the calibration bits in RTCGCAL onl ...

Hi there ,

I have a few questions with regard to writing to SD and FAT16 formatting.
I need to build a device which is capable of logging RF data to an SD card such as RSSI message length type etc ...

I put a 220nF cap to ground on pin14 and I also placed a 1,5k pullup to D+ pin16.
