![]() I spent two days with this screen and still nothing. I downloaded the ili9488 libraries from but it even doesn't allow to choose ili9488 chip.Ĭould you write me which version of these libraries are good for this shield and with which setup? I tried to revive it with UTFT as well as mcufriend_kvb libraries with so many different setup but it always shows me "white screen". (It is very similar shield like Romeo's first link but only 3.5 inch size.) Thank for your post I even didn't try the R61581 thing. It says in back that the controller chip is ili9488. I received a 3.5 inch TFT LCD Arduino Mega shield via Aliexpress. Why, there is a specific LCD shield for mega2560 if the LCD shield for the uno works fine with it ? Is it a 8 or 16bits parallel data bus ? or via SPI bus ? Work fine with MEGA2560 & UTFT or MCUFRIEND_kbv libraries. I also know, I can not fit on top of the ethernet shield a LCD shield, but that's not a major problem. I know I can not use SPI for a other shield.īut that's why I asked you in my previous post, which pin are used on the LCD shield ?Īnd could I re-define these pins if already used ? This shield uses only 4 pins (50 to 53) for SPI and pin 4 & 10 (they can to be redefine if needed) for chip select (SDcard or Ethernet), not more. If I can mix every things, I will be happy. I'm able to send all data to the network. My sketch with the ethernet shield is ok. My final project is to be able to send some data (from different probes) to internet and to have a dashboard on a LCDĭata from probes come via RF433 module. Sorry for all these questions but I try to find the best way before to go head and buy the right LCD TFT TouchScreen compatible with the Mega2560 Maybe, I will have to use a couple of external wires if I can not connect them together with the pinsĬould you confirm the both shield (LCD + Ethernet) are compatible on a MEGA2560. The ethernet shield uses the SPI pins (50 to 53) via the ISCP connector and pins 4 & 10 for chip select (SDcard or ethernet). I already have this shield (wz5100) and works fine alone with the mega2560. Moreover, in the next step of my project I would like to add my ethernet shield. So, I think it will be useful to have the microSD efficient with a TFT if possible I found contol pins definition A0->A4 for LCD_rs, LCD_rd. Where I have to indicate the pins used for the differents LCD Shield in the library ? How the the same library can work with 2 different shields connected differently ? Is it still a 8 bits parallel or 16bits ? or via serial SPI ? With the LCD shield for mega2560, I don't know which pins are used. With the LCD shield for uno, digital pins 2,3,4,5,6,7,8,9 should be used with the mega2560 Maybe this library (from you Hi.) is running better now. I was a little bit confused with the MCUFRIEND_kbv library because you said somewhere "It will work on a MEGA2560 but not very fast" and it was confirmed later in a previous post. In the UTFT Supported display modules infos, I do not find the "ili9488". I could use either one or other with both librairies on both shields You confirm that "ili9488" & "r61581" controllers run with UTFT library & MCUFRIEND_kbv library on a MEGA2560. I had read a lot of posts very useful from you, thanks again !! We can read a lot claim for this kind of LCD since several months but is there anyway to use this kind of LCD now with my Mega 2560 without any problems or I have to wait ?Īny answer and advice should be appreciated. What's the difference between both expect the pinout. ![]() I know this board is running good with the uno. There is also a similar lcd shield here for the Uno & Mega board ![]() I also read that TFT is slow with the mega2560.Īlso some guys have some troubles with the touch screen. What's the right library for a ILI9488 controller. We can find a lot of libraries official, unofficial, customized and others for some specific controller. My goal is to use the TFT 3.95'' cheap lcd for my project.Ĭould you confirm the lcd from the link below, is really compatible with my Mega board ? I have a Arduino Mega 2560 board and looking for a tft lcd touch screen.
