I'm working with the dspic33ep512mu 810 and a 48 mhz crystal.
I need a timer with a frequency of 1 hz.
Due to the timer properties in the flowcode, the frequency of at least 1,431 hz ((Fosc / 2) (1: 256) (65536)) can be done. What trick can I do to achieve the timer frequency of 1 hz, without changing the crystal (48 mhz).

Thankful;

Ricardo.

You could try to calculate a more frequency interrupt (like 5 a second) and use a counter in the interrupt handler to only execute the code you need to run at 1 hz when the counter reaches 5.

Hello kersing;
grateful for the attention.

Can you give me an example in flowcode?

I don’t have a computer with Flowcode handy for the next 48 hours so may-be you can try yourself and post the result here for me to take a look at after the weekend?

Hello Kersing;

Sorry, we're over the weekend. Make the most of it.
I didn't even realize it, it was my excitement.
I made a little code. Would it be more or less like this?
See you on Monday.

Thankful;

Ricardo.

Hello,

Here's an example of what Kersing suggested.

I ramped the timer rate up to 25Hz and then using a variable I count the number of interrupts up to 25 to give the 1Hz interrupt you require.
