Tft spi arduino12/4/2023 ![]() ![]() The RS8875 has two SPI interfaces (Display and EEPROM). Your pinout seems to show a 16-pin parallel interface and two SPI interfaces. Then set the SIFS pins to 1,0 to select 4-wire SPI. Looks like you set the PS pin HIGH to select Serial (SPI/I2C) instead of the 8/16-bit parallel interface. I will be using the pin names from the datasheet. It looks like the labels on your pinout don't match the labels the manufacturer uses for the RA8875. The Wireing is correct because the Adafruit BreakOut Display works with the mentionated Code properly.īodmers, Schreibfaul Code do not go over the Compiler.The first hint would be to read the dtasheet: The same Problem with Waveshare 2,8 HX 8347D. Every metionated Code, with fited Wireing work fine whit Adafruit Display but not whit Wavechare. The Codes i try are the Example Code from master MCUFriend, Adafruit GFX, TFTLCD, UTFT, HX8357, ILI 9341 on UNO, Mega and DUE with the correct Wireing Setup. The Waveshare Testcode based on Adafruit Code. I made the Change by Wire up the Dsiplay. I Buy the Adafruit 3,5 TFT an hope to find a SPI code that let the Waveshare TFT work because the SPI Hardware Description is identic whit the Waveshare. The Display, HX 8357/ ILI9684/ SPI do not accept change to Portrait Mode, do not accept UTFT, UTFT Geo, McuFriend Code at all. Only the Testcode works fine but nothig else. ![]() Waveshare TFT 3,5 fit perfect in the cluster but the TFT do not work. Probably wrong Deffinition of the two SD Slots. The Qita 3.2 TFT fits good in the cluster but ther are to many Wire for Conection an there ist a Hardware Inpact with the Can Bus Shild. I like to use the full Window and i need to change the TFT on 3,2". The Window in the Cluster ist a little bit bigger than the actualy used 2,8" TFT. The Setup is Arduino Mega, Seeed Can Bus Shield, K-Line Shifter 9637D. My first Project is a Driver information Display for Audi and it work well. I am new Arduino User since January 2019. Eventually leading to a 4-stripe that goes to a 4-way ribbon. Touch panels have a gold stripe around the active TFT area. Have you got any Touch panel fitted to the TFT ? Have you tried measuring resistance between A1,D7 with a DMM ? broken XĪ successful diagnosis of X, Y pins looks like this: Testing : (A1, D7) = 30 it is finding Yīut does not find any valid resistance between A2, D6 i.e. The sketch finds 38 instead of a typical 30. The Y direction is ok for most of the screen. So it is obvious that the X-direction is broken. There is a diagonal crack in the glass at the bottom left side of the screen. I deliberately ran the Calibration sketch on a broken ILI9486 screen.

Would read low when digital is written LOW Typical 30k Analog pullup with corresponding pin Making all control and bus pins INPUT_PULLUP Pin connections are given below for the shield.īroken touchscreen as well in TouchScreen_Calibr_Native : Attachment shows my display and the rear of the LCD Shield. This folder has touchscreen library files. In the Kumantech zip file, under Install libraries folder, copy the TouchScreen folder to your libraries folder. Make sure you have given proper BMP file names in the code. It must work.Ĭopy any four, 16 bit or 24 bit. ![]() Under examples run the graphictest_kbv.ino. you may have to keep doing this for all your sketches. Under examples run the DisplayString.ino.

See lines mentioned below to ensure touch pin connections. Next, run the example file - diagnose_Touchpins.ino. See line mentioned below to ensure ILI 9486 is detected.
