I bet if we looked at the circuit board of the camera we will find an ILI9225 or it's competitor near the ribbon socket. If that LCD just has the ribbon cable, then it will be near impossible to drive with an Arduino without adding in the ILI9225 to do the high speed bits. The ILI9225 allows for sending images to the screen without having to handle the clocking demands of the LCD. The ILI9225 is super common and used to drive screens just like the one OP has, but without seeing the back of the screen, I don't know if it has one. I may be mistaken but isn't the ILI9225 an LCD driver chip, and not the screen. You need to check that too, starting with supplying 3 volts and ramping it up until they light up. You may need to test the pins with a multimeter or I think you can even do a visual inspection on the pins (for example: according to the first pin layout the first and the last pins should have been connected together)Ībout backlight: There are generally 4 leds and they could be either in parallel or series, so if we assume a single led has a 3v forward voltage, you may either need to supply 3v (parallel) or 12v (series). Since there is no further information aside from what you provided I can't help it further. Anyway, here are 2 of the pinouts I found:Ģ1 pin: 1 = GND, 2 = IOVCC (1v8 to 3v3), 3 = VCC (3v3), 4 = CSB, 5 = RESET, 6 = PS, 7 = WRB, 8 to 16 = DB0 to DB7, 17 = BL_A, 18 to 20 = BL_K1 to BL_K3, 21 = GNDĢ2 pin: 1 = BL_A (backlight anode), 2 = BL_K (backlight cathode), 3, 4 and 5 are not connected, 6 = VDD, 7 to 14 = D7 to D0, 15 = RD, 16 = WR, 17 = RS, 18 = CS, 19 = TE, 20 = RESET, 21 and 22 = GND (probably this one) ![]() As far as I can see from the picture, it has 21 pins but it also says it is 22 pins on its ffc. The hardest part is figuring out pinouts. The controller of that screen is (generally) ILI9225(G), and I found so many tutorials to use it with an arduino.
