RPi type A and ILI 9341 #39

#33 |
I've been asked similar questions so far, but most of the time it's because the right driver isn't selected. The appearance alone cannot determine the correct driver. Use this to check. Never believe the seller's information. |
I checked it on arduino uno and see ILI9341. And on arduino lcd excellent work, but on rpi doesnt( |

Do you supply 5V to the TFT? When a regulator(It's often AMS1117) is mounted on the back, it's operated 5V. |
I have tried both 3.3 V and 5 V. |
But you use more pins in your schematic, I don't really understand how I can apply them in my |

Installed latest raspbian full, install wiringpi (https://github.com/WiringPi/WiringPi) and have this problem... cc -o demo demo.c fontx.c tft_lib.c driver.a jpeg.a png.a -lwiringPi -lm -lpthread -DILI9341 |
Installed a clean retropie, wiring and copied your driver again and again the same thing on the screen( |
WiringPi may not work properly with retropie. WiringPi is a very old library. raspbian may have compatibility issues. |
Good afternoon, I am trying to connect an Arduino LCD Shield with ILI9341 to a Raspberry Pi model A, but it does not work.
Your schematic uses the full comb of pins from the RPi model 3, so I reassigned the pins to those of my RPi version.
Unfortunately, I always get a picture like the one in the picture.
Below in the schematic and in the config pins.confiring the pins I used:
#Number is WiringPi Number(NOT GPIO Number)
RST=7
CS=8
RS=9
WR=11
RD=10
D0=0
D1=2
D2=3
D3=4
D4=5
D5=6
D6=12
D7=13
#If your TFT is 8 bit Parallel,A definition after this isn't used.
D8=2
D9=3
D10=4
D11=5
D12=15
D13=16
D14=29
D15=30
My LCD module looks like this:
I have tried reassigning the pins several times, but I either get the same thing as above, or just a white screen.
I really need your help!
