dsPIC33CH128MP506 CLC [ WORKED !!!!]
PostPosted: Mon Aug 15, 2022 4:59 am     Reply with quote

I want to use CLC peripheral with dsPIC33CH128MP506 processor. I want to control 1 output with signal from only 1 input. Incoming PULSE information is 400ns. 200ns ON. 200ns off. I want to capture this incoming pulse information and control the output as a toggle. How can I do it?

Start by pulling the Microchip CLC configuration tool:

Have a look too at their tutorials on this:

https://microchipdeveloper.com/8bit:clc
[/url]

It sounds as if you want a standard D flip flop, with it's output inverted
and fed back to it's input, so you get an inversion on every clock. Then
just feed your input signal in as the clock.

With the configuration tool you can see what logic you need, and then
just copy this into the setup_clc lines in the compiler.

I did like the example below. But it didn't work.

Code:

#include <33CH128MP506.h>
#fuses NOWDT
#device NESTED_INTERRUPTS=TRUE
#use delay(clock=180MHz, crystal=20MHz)

#define A_INPUT                       PIN_B12

#pin_select CLCINA=A_INPUT

#define LEDOUT                       PIN_B14

#pin_select CLC1OUT=LEDOUT


void main(void)
{
   //setup CLC1 inputs
   clc1_setup_input(1, CLC_INPUT_0);   //CLCINA (A_INPUT)
   //setup CLC1 gates
   clc1_setup_gate(1, CLC_GATE_NON_INVERTED_INPUT_1); //A_INPUT
   clc1_setup_gate(2, CLC_GATE_SET);
   
   //setup CLC1
   setup_clc1(CLC_ENABLED | CLC_MODE_AND | CLC_OUTPUT | CLC_OUTPUT_INVERTED);
   

   while(TRUE)
   {
   
   }
}

You are not setting up a flip flop, so no wonder it doesn't work.

Look at this thread:

ok it worked. No need to flip flops. I'm approximating the incoming pulse in 100ns. If the input is 1, the output is 1. If the input is 0, the output is also 0.

You said you wanted the output to 'toggle'. That implies a flip-flop.....

That's exactly what I said. Output 1 when input is 1, output 0 when input is 0.

That sounds like a buffer

Yes, that is just a simple buffer gate, not a toggle.

To have any hope at all of helping, we need to know what programmer
you are using, and what software to drive it.
Display looks like something like possibly MPLAB, rather than CCS.
Nothing there looks like an error.

CCS C 5.109

ICD U80

So, you are using the 'Program' option from inside the IDE?.
Try using CCSload directly instead.
CCSload itsefl is what is being called by this option, but run directly it is
more likely to tell you the error. It also has diagnostics allowing you to
test what is happening.
I still do not see an error being reported.

The U80 is very prone to problems if the cable or connection is not perfect.
I use cables half the length of the supplied ones, and these reduce problems
massively.

So, what do the diagnostic selections say?.

Firmware up to date.
Do all the pins test correctly.

The point is that CCSLoad allows you to test things.
