It shouldn't cause any issues - as long as the type is for the same or a larger type then everything will work. Note that having a long for the index means that the lookup table can have up to 2^32.entries (unlikely on an mcu). The returned value will be the same (and correct) as long as you use a s...

I created an example 'camera' Compile cd camera idf.py add-dependency "espressif/esp32-camera^2.0.9" add #include "esp_camera.h" to supplementary code (and save) idf.py fullclean re-compile You should find a 'managed_components' directory (including examples) idf.py menuconfig -- components -> camer...

I posted a bit about using the camera a while ago (see https://www.flowcode.co.uk/forums/viewtopic.php?f=3&t=1679&hilit=Camera -) Yesterday I finally managed to add a component to a flowcode program the espressif way - though it is not for the faint of heart.. I am using the espressif tools v5.1.1 C...

There is - but it is a little bit 'clunky'

Another advanced idea for esp32 users. A useful feature of the esp32 is the ability to use some of the flash memory as a file system. This is accessed using standard 'read' and 'write' commands (amongst others) and data can also be written to he 'disk' space from a PC. Multiple files can be used - a...

Surely - if you have enough pins left?

Strangely - UART is 'almost'' one wire comms (I know the reply is on another wire!) - but the receive is purely timing with no clock...

I was going to have a little play - but too often the real stuff gets in the way :-(.. What speed is the target (slave) clocked at? - I don't have a PIC12 to hand, but it might be possible to mark the MCU 'specific' bits (if there are any) - I think it should be okay to do a start timer on pin chang...

Microchip have some interesting bits...

I also found something about using the USART on PICs to do a 'hardware' implementation

Just one - with a stylish two tone PCB

Also don't forget the pull up resistors!
