Thought I'd put in here as it's not so much an ESP IDF question as a general C question. For the sake of making my code logical/easy to read I'd like to put some #DEFINE statements in with the gpio_config statements I have in a void pin_setup() function. Is it legitimate to have a #DEFINE at this le...

Thanks @microcontroller, I wasn't sure if there was a different way of interfacing with the pcf8574 or if I just needed to go down that route. Cheers!

I have a project that already makes use of the components from Unclerus, including the hd44780 for driving an LCD display. I need to expand my Gpio ports so I've added a discrete pcf8574 board in. Now I already have the includes in my project as it's part of the lcd setup. I can happily read from th...

Fab, up and running, something so simple! Thanks for the help tracking it down.

Nevermind, turned out I only needed to edit two lines in my platform.io to get that. Hurray for being able to google whilst waiting for the kettle to boil!

Will do but it will be later on I'm afraid as I'll have to read up on how to do that!

Thank you for all this help .

Thanks, I've now added this to the top of app_main() red_line_queue = xQueueCreate (10, sizeof(unsigned int)); and we're onto a new error now! (facepalm). Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled. Wondering if I need to scrap all my code for this and copy-past...

Tried creation through both xQueuehandle and xQueueCreate and not had any change with either approach sadly.

Well that might be the root of my problem then.... Surprised it compiled without that! I'll make the amendments later and see if that sorts it. Thanks.
