The Neopixel of the 12864 Mini are working fine but the screen itself stays blank. I have used the following Pins:
[board_pins]
aliases:
# EXP1 header
EXP1_1=PE9, EXP1_2=PE10,
EXP1_3=PE11, EXP1_4=PE12,
EXP1_5=PE13, EXP1_6=PE14, # Slot in the socket on this side
EXP1_7=PE15, EXP1_8=PB10,
EXP1_9=, EXP1_10=<5V>,
# EXP2 header
EXP2_1=PB14, EXP2_2=PB13,
EXP2_3=PF7, EXP2_4=PB12,
EXP2_5=PE7, EXP2_6=PB11, # Slot in the socket on this side
EXP2_7=PE8, EXP2_8=<RST>,
EXP2_9=<GND>, EXP2_10=<NC>
and those klipper config entries:
[display]
lcd_type: uc1701
cs_pin: EXP1_3
a0_pin: EXP1_4
rst_pin: EXP1_5
contrast: 63
encoder_pins: ^EXP2_5, ^EXP2_3
click_pin: ^!EXP1_2
[output_pin beeper]
pin: EXP1_1
[neopixel fysetc_mini12864]
pin: EXP1_6
chain_count: 3
color_order: RGB
initial_RED: 0.05
initial_GREEN: 0.5
initial_BLUE: 0.5
The display is working fine at a Manta M4p but not at the M8P. I tried different cable in different directions of the plugs, no way.
