I'm going to ask a very general question.
here I can use a CRC both via hardware and software

Is there an advantage to using hardware?

re: needed this output to do an adc adjustment to find the closest power supply (~5V) in real time as it fluctuates under some conditions.

if you're saying VDD is changing ,you need to seriously r ...

Thanks for the tip.
It has clarified enough the fact of being able to read the fixed reference.

In dspic I do the same thing,
I read the VBG (voltage bandgap) and do the calculation for ...

Good afternoon everyone.

in the datasheet of pic 16f886 it is indicating that it has a fixed voltage of 0.6V for reference.

But I didn't find how to configure

I tried to set the bits
FVREN = ...

Thank you all for your comments.

Unfortunately, I won't have access to these two hardware anytime soon, as I'm on vacation.

However, I can say that in the most "slow" DSPiC, if I set t ...

Configured these two microcontroller with practically the same parameters.
It is very simple programming.

With an oscilloscope I noticed a curious thing.

The 33FJ16GS504 oscillates twice the sp ...

Good morning everyone.

Most of the protocols available for communication between electronic components on the same PCB (I2C, SPI, etc.) there is no "checksum", that is, what arrived, arri ...

Hello good afternoon everyone.

Well at the beginning of the microcontroller programming it is possible to adjust some communication parameters like baudrate stop bit, parity, timeout .....

First of all thanks for responding.

And for remembering that I could "tighten" Pull Up (which was in 3K3) ...

The hardware (PCB) is already ready, has a ground plane on both surfaces, ...

I have an i2c device that supports 1 MHZ, 400 KHz and 100 Khz.

It is an F-ram memory, the equipment will be a data logger so I need quick and constant recordings in the memory.

The speed of 100 ...

I've solved the problem ......

if someone has the same problem ...

the parameter was missing:

"ADC_ENABLE_SHARED_CORE"

setup_adc(ADC_CLOCK_SYSTEM | ADC_CLOCK_DIV_2 | ADC_WARM ...

I made a simplified example of how it freezesL

#include <33CH128MP506.h>

Hello, good morning everyone.

I have a card with a dsPIC33ch128mp506.

After a lot of "fighting" I managed to activate the two nuclei and, they are almost fully functional, just missing ...

Can invert the PWM signal?
Instead of starting positive, start negative for one of the PWM

setup_compare (1, COMPARE_PWM | COMPARE_TIMER2);

setup_compare (2, COMPARE_PWM | COMPARE_T ...

SOLVED !

I removed the "disabling the serial"
it's been running for over an hour
the problem occurred in less than 5 minutes.

As I still have a lot of RAM space, I put a value of 102 ...
