One of those 'speed kills' things.

Static CMOS consumes very,very little power,with proper pullups.

Active CMOS consumes power ,based upon speed and/or 'transactions' (0/1/0/1/...).

Going fro ...

dear every one,

I have some difficulty with my pic and the pll.
At 8Mhz (no pll) > Consumption OK
At 32Mhz, my consumption is more 30mA !!!

your reply is -always- rapid and clear.
thanks for all

it's works perfectly

My need is to store 3 16bits value. no more.
The value is like offset / setting of my system.

Sure, add a little I2C eeprom is one solution but add it for so little data seem to be luxury.

Have ...

dear eveyone,

My question is about saving data into memory program, as an eeprom.
My pic : 24fj16ga004.

I have found a lot of explain, but i'm already confused.

What I think:

Thanks a lot
Peripherals in the 16bit PIC's, by default are fed with Fosc/2.

Dear friends,

I have a problem when i try to set my timer.
I'm not able to understand correctly how it works.

Please post a link to the datasheet for the RFM69 module you're using. You've got 'extra stuff' in what I'd think should be simple 'read and writes'. That may be causing problems....

Dear forum,

I'm back with a new question.
I'm working to write a code for a project. I use a DevBoard Microchip Explorer16 with a PIM 24FJ128GA010.
Connected on board, a RFM69 module.

I have s ...

dear everyone,

I have made a very little circuit on a dev_board for playing with sleep/deepsleep and watchdog wake up.

Thanks to Ttelmah and PCM programmer, you have right !

I had two errors in code/mind.
The first was that I didn't test if the CAN have finished to convert before read the result... the code from ...

I see that chip has two modes, single or continuous . My guess is that you've set it for 'single' reading mode which automaticly 'powers down' to save energy.
You should printout the actual 'configur ...
