Hello,
I use TX2 SPI + 2 GPIO pins to send image to both RGB oled screens.
My connections are as follow :
-
Spidev3.0 :
Mosi
CLK
CS -
GPIO :
GPIO298 as DC
GPIO 388 as Reset -
Power :
TX2 Ground
TX2 5v -
frequency :
8Mhz
All wires are 60cm : the last 10 cm are Y form.
Both Oled screens are used as robot color eyes, and they share same wires.
When using 20cm Y wires (Card of experiment wires), both oleds screens are perfect !
When using 60cm (thin servo wires) they don’t work !
(If i only connect 1 eye, it works. But not when Both screens are connected at same time)
What could be the cause ?
Thanks a lot.
Vincent
