Ok, i stop to try to work with the ht16k33 and return to the « good old shit » alias the max7219.
Spi nor i2c...
With a delay of 100ms for the setup, it works fine (everytime) and is cheaper and easier to find!
Thanks for your help @allObjects
Ps: i tried to remove the 10k with just a bridge... and with a 4k7... no more results... grrrrrrr
I was looking for a solution to have only 3v3, but it does not work as expected .fu...
