A couple of questions...

Is this the right sleep instruction: sleep(REG_LOW_POWER);

(I'm trying to go into sleep mode, not deep sleep mode)

One stupid question...Are you connecting the crysta ...

Hello,

I'm trying to set up the MCU to work with a 32.768KHz secondary oscillator but when I read the rtcc, always get the same time. There's no increment.

How should I setup the timer1 in order ...

Hello,

I think I have a concept problem with the DEEP SLEEP feature...

This is my source code:

#include <main.h>

#INT_EXT

void EXT_isr(void) {
clear_interrupt& ...

Hello,

I'm creating a new project with the PIC18F46J11 and the help of the wizard.
After selecting this device I tried to setup the HLVD but this option is disabled. I checked on the datasheet ...

I thought you said it was drawing mA?.

2.9 uA

Given you are referring to having the secondary oscillator running, and I'm not sure from your current descriptions whether things like the brownout ...

And (of course), if the pins are not connected, what are you doing to stop them floating?. You do understand that a pin should not be left as an input, with nothing driving it, if you want low power?. ...

What instrument are you using to measure the current ? Have you
checked the instrument with, say 3v running through a 1 MegOhm resistor ?

I'm using a multimeter UNI-T UT71C. I measured 3 volts ...

That was my first conclusion but then I removed the regulator, powered
the board directly at 3.0 volts and the consumption still remains above the 3mA
That's a 1K load, or maybe three 3.3K loads ...

Where are you measuring the current ? At the board's input power
terminals ? If so, you have a LD1117S33TR regulator as U1. This
regulator has a quiescent current of 5 to 10 ma. That's probably ...

Look at figure 2-2 in the data sheet.

Read this paragraph:

"During programming and debugging, the resistance
and capacitance that can be added to the pin must
be considered. Device progra ...

just a couple of comments from a 'dinosaur'..

1) the schematic would be a lot easier to read if all +5V terminations were 'pointing up' and all grounds were pointing 'down'. yeah I'm old but was ta ...

Hello,

See schematic on: http://tinyurl.com/deepsleep-pic24

This is the complete schematic of the pcb in which we want to decrease the consumption.

Hello,

I know this is a very frequent question but I tried to solve it by searching on the forum and I failed...

This is my source code:

main.h

#include <24FJ128GA310.h>
#device ICS ...

Hello

Is there anyway in CCS IDE + ICD3 to set up the ICD3 in order to power the target directly?

Since MPLABX allows this setting I'm not able to figure out how to change it under CCS Ide:(
...

hello everybody,

Ttelmah: We have been trying to use fast_io, but with no success.

temtronic: You mean an AND gate?

Thx
