Pokitto as programmer?


#1

i was wondering how to turn the pokitto into a programmer (binary file from sd card to pex device)
i want to try out some hat ideas but would need this to work for firmware updates or just reprogramming a hat


#2

Programming what exactly?
Burning a bootloader to an Arduino?


#3

yes, arduino’s, teensy, esp23

not sure how different there reprogram commands are


#4

The biggest problem is the voltage difference.
Most Arduino boards are still 5v.

This is along the lines of something I was working on a while back…

I managed to make the voltage protection circuit, but I gave up after successfully transferring one bit of data.

To allow the Pokitto to actually work as an ISP though, you’d need the Pokitto equivalent of the Arduino ISP sketch:

(As well as a voltage bridge.)


#5

no that wont be needed for the selection i was looking at, arduino due, teensy, esp32


#6

What won’t? The voltage bridge or the ISP program?
(I don’t know if that’s the proper name, but that’s what I’m calling it.)


#7

voltage wont be needed since there all 3.3v chips
no idea how the ISP applies to the the esp32 and teensy and instead of using a the arduino ide to programing it over usb but from sd card true pokitto as programmer
