Is possible to send bitmap with i2c protocole ?

Post by keokod » Sun Mar 20, 2022 4:30 pm

Hi,
in pi pico I have a picture bitmap (240px X 240px), I would change this file with the same name.
my connection is:
ESP32 => protocole I2C => pi pico.

I would like crush this bitmap another picture with the same name.
Preaps I would like use I2C if is not possible change protocole I use another ?
with ESP32 wifi, I receive à newer bitmap And I would change bitmap who is in pi pico.
the name file is "CIRCUIPY E:/imgs/demo.bitmap"
Is possible to ESP32 Send bitmap and crush bitmap in pi pico ?
Is it have à tutoriel simple for it?
thank's for help.

You can decode and display BITMAP images with ESP32 but I don't really know if your job is possible using the I2C protocol.....Never really read anything related to such a project. Let's see what the experts have to say.

So the question is: can you sens binary data from ESP32 to RP2 using I2C. The requires support of the I2C slave mode at the Pico. What should work is using UART. That works in both directions.
