Topic: TFTshield : how to RESET pin? (#define LCD_RESET A4->RST?) (Read 3738 times) previous topic - next topic


Thanks, Samond!

I also saw this info from another seller. But when I purchased this module - it was told that Mega is also supported.
Will see if it's possible to do something on Mega with it  :)


Still the same white screen.

I've found some info about pin differences between UNO and Mega,
that LCD_D0 ... LCD_D7 should be connected to pins 22 ... 29, not to 2 ... 9 on Mega.

Can anyone say, if it is really so?



I have the same issue on Arduino Uno, I bought this LCD touch 2,4 tft and it wants 5 analog pins while on Uno board I have only 6 of them and 2 are needed for RTC module which uses analog pins too. I defined LCD_RESET=A6, connected LCD_RST to RESET pin on board and i have white screen, when I connect the wire to A4 everything works.

Ahh! yes it worked !!! I connected LCD_RESET to digital 10 pin and defined LCD_RESET = 10. Everything seems to work or I did something wrong ?


you can just wire lcd A4 to lcd reset pin and break the pin goes arduino A4 and use arduinos a4 as u wish.
