Re: 16f18877 internal Zero Cross Detector

The pin declared in properties is for output - I'd connected this (RD1) to a logic analyser - it was easier than wiring up a UART convertor... The zero crossing interrupts on RA0 - I think this is fixed on the 18877 - but other PICs might be able to remap to other pins.. This is set up (analog / in...

Re: 16f18877 internal Zero Cross Detector

Found the issue - unplugging the PICKit and the speed increase at which it works is dramatic - I changed to using 32MHz internal - and running happily at 100kHz (with mods as per previous post) Martin Finally had an opportunity this weekend to go over your code which I very much appreciate. Ive lea...

Re: 16f18877 internal Zero Cross Detector

Thank you. 20ms would be 50hz. My reason for implementing the ZCD is triggering. The idea is to trigger the AD9834 at zero cross over to either increase or decrease, through software, the output phase to hopefully sync the AD9834's output to a signal and track it utilizing the AD9834's pselect pin (...

16f18877 internal Zero Cross Detector

The 16f18877 has a Zero Cross Detector as one of its CIP.
I cannot find this component within FC.

Is the ZCD accessed by utilizing the "CODE" command icon within the flow chart?
Or am I missing something?
Did a search within FC and no results.

Online courses

Does anyone recommend or know of any online tech school having courses on programing microcontrollers? I searched and looked at a few but they are not helpful. Most are hard to understand Indian instructors and the material is dated. Not to mention they really just show how to blink a LED or the typ...

PC is crashing (32 bit when I have a 64 bit windows system.)

Installed V11 and upgraded to Professional. Followed an official Matrix youtube example using the DSP components. System immediately freezes when I run debug. Task manager says my Flowcode version is the 32bit version. When installing flowcode the installation process apparantly installs the 32 bit ...

When did you buy the v10 chip pack? Maybe we can transfer it over for you?
Bought the PIC-8 on July 21 2025.

Bought the BL0011and BL0114 to learn with in Sept 2025 and plan on purchasing the Professional for the oscilloscope and other tools it has.

Re: AD9834 DDS

Hello, I've had a go at a component for you, it should be available now from the library updates in v11. Just make sure you do a full component update and it should be there. If you have a go then please let me know how you get on. I was able to get V11 installed and did a full component update. I ...
