(More details coming up and sorry if this is a stupid question!) And I think I've bought some fake display. But the display still don't have anything but a white screen of death. But there's something on the TXO and RXI pin that I suspected It was the data lines.ĮDIT: OK after some probing I found out the data lines on Pro Mini using UTFT was from pin 0 to pin 7 exactly. I've also had a Mega 2560 and logic levels converter but it still didn't work.Īnother thing related to the problem: When I follow the guide to wiring the pinouts for UNO to Pro Mini and compile the code (referring UTFT requirements document), I can't probe out any signals on DB0 to DB7 (pin 7 through pin 15 on Arduino Pro Mini), so obiviously I'll had a blank screen. This is the second display I bought and it doesn't seem to work either (the old one I think I've burned it down when connecting it to 5V line). This give me a headache over weeks and I can't figure out why. (I've tested Blink and it runs perfectly on all pinouts on 3V3 after pushed code with 5V CP2102). I've choosen 3V3 - 8Mhz in the Arduino software when pushing code to it and then plug it to my good old PSU which provides 3V3 line to both the board and the LCD. I'm using Silabs cp2102 USB to UART converter to program it in 5V. But I thought UNO also has Atmega328 and if it can handle 8 bit LCD, there's no reason why my Pro mini can't.
8/16 bit TFT LCD is not somewhat designed to work with Arduino Pro Mini (maybe it has too few pinouts?) because what I found when searching for "Arduino Pro Mini" together with "TFT LCD" resulting SPI LCDs, not parallel LCDs like this one.But why? I'm currently thinking about the following reasons:
#8bit drummer nano death how to
I followed many articles on how to wiring them up and pushing codes to the tiny board but every attempt comes up with a blank - white display. The LCD data pins is 8 pins from D0 to D7. I just bought an ILI9325 TFT in 8 bit interface and an Arduino Pro Mini.
