So multiple SPI devices on the same bus is only important when you use SD card. Mind you, he has no concept of reading SPI. I suspect that you will need to use completely different pins for each constructor with software SPI. Note that Mr Karlsen has no concept of hardware SPI. I guess that you could create two separate UTFT objects. I am sure that Seeed's TFTv2.h library "works" for a single Shield. ![]() two separate Adafruit_ILI9341 objects that both use the Hardware SPI. This should be fine for libraries like Adafruit_ILI9341. You can access A6-A15 with angle header strip. ![]() The Touch pins of your second screen can have XP, YM on the 18x2 but XM, YP must be Analog. This contains the hardware SPI pins (50-52) and you can select GPIO pins for CS, DC, RST. The second shield would need to be connected via the 18x2 header. I would guess that one shield will plug into the Mega2560 as Nature intended. Not that you wanted to connect two displays to a single Mega2560 at the same time. I understood that you had bought two items. The display works when i plug it right onto the mega board but that does not help at all because i need to rung two displays with one mega board and the documentation from seeed studios is sh*t. I haven't seen any tutorial how to connect the displays to the mega board without directly sticking both together. The display works when i plug it right onto the mega board but that does not help at all because i need to rung two displays with one mega board and the documentation from seeed studios is sht. Changeing my sketch to the right pins and connecting the display is then way more easy. What i know is that the ILI9341 is supportet by the UTFT lib that I already use. I have to configure several things I don't need and I don't know about. If you had read the documentation you would have seen they recommend their own lib at the moment. it will run out of the box on Uno, Leo, Mega2560, Zero, Due. You would not need to make any of the solder bridges. I would assume that the TFT will use the 3x2 SPI header. Then run whatever library Seeed suggests.īut you should be able to use several other libraries. Surely you just plug the Shield into your Mega2560 header sockets.
