You are right. (as always!)

Spoke to Richard @ CCS last night, and had this reply.

So I determined that the problem is an error in the enable_interrupts() function when INTR_CN_PIN or'd with t ...

Hi Folks,

Sometimes the simplest things seem to be the hardest.

I am trying to generate an interrupt on change from PIN_D13 on the DSPIC33CK64MP105. (Using Compiler V5.096)

To enable it I ...

In fact I have a couple more questions, firstly it's the receive pin of the UART that I want to disable not the transmit - is there a bit to disable the UART RX PIN.

The pin I want to un-select, is ...

Thanks - I will give it a go once my board is built, and report back.

Cheers

James

Thanks - I will try it.

However I need to do the same for the UART as well, as I want TX only. Can this be achieved using something similar

Hi Folks,

I've got a product I designed a couple of years ago, that I now need to design an expansion board for. I've only got a limited number of pins on the expansion port.

I'm using a PIC24F ...

Hi Folks,

Hypothetical question. I've got a PIC24 in a system running great, and doing just what I need it to. It's connected via a modem to a web server that we've also created and all is hunky ...

Found it! In order to debug what the deep sleep current of the processor was and get it as low as possible, I fitted a jumper link to to the VCC supply of the processor. This meant I could wire in a ...

I am running the RTC on the internal oscillator (SOSC pins are I/O but not connected).

setup as below.

/* TURN ON AND RESET THE CLOCK */
setup_rtc(RTC_ENABLE|RTC_CLOCK_INT , 0); ...

And after a triple check, without these two lines in the code it won't reliably start up and frequently locks up taking about 820uA and the only way to recover is a hardware reset!

With this as a s ...

OK - I am moving forwards, albeit in a somewhat fumbling manner !

With a bit of tinkering to my main() I've got it to a stage where it reliably restarts from deep sleep for both the EXT0 or the RTC ...

RTCC still has no real effect

This gets even stranger, I have now amended my main code to look like this (declaring both registers and then reading them, then forcing a clear of the release bit.

/* MAIN CODE */
void main&# ...

However I can report that neither of those has made any difference to how it works - and it still half wakes up when the RTC interrupts the system and then the power drops - and then says it wasn't wo ...

However if I declare the start of main like this instead. . . .

/* MAIN CODE */
void main()
{
UI_16 RConRegister;

RConRegister = RCON_REG;

/* STAGE 1 - READ THE ...
