My TFT LCD 2.8" ili9325 don't work, only white screen #4

Closed laserayaneh closed 4 years ago

laserayaneh commented 6 years ago

Hi, I have a TFT LCD 2.8", this TFTLCD work fine with Arduino Uno and Arduino Pro Mini and other Arduino board with library and examples of https://github.com/adafruit/TFTLCD-Library in Arduino Pro Mini serial port show this: :-) Using Adafruit 2.8" TFT Breakout Board Pinout TFT size is 240x320 Found ILI9341 LCD driver ... Wiring in Arduino boards is: LCD_CS --> A3, LCD_CD --> A2, LCD_WR --> A1, LCD_RD --> A0, LCD_RESET --> A4 and 8 data lines is: D0 --> 8, D1 --> 9, D2 --> 2, D3 --> 3, D4 --> 4, D5 --> 5, D6 --> 6, D7 -->7

I use this code: https://github.com/adafruit/TFTLCD-Library/blob/master/examples/graphicstest/graphicstest.pde

Now I have an STM32 (STM32F103C8T6) header board and wiring is: LCD_RST ---> PB7, LCD_CS ---> PB6, LCD_RS ---> PB5, LCD_WR ---> PB4, LCD_RD ---> PB3 LCD_D0 ---> PA0, LCD_D1 ---> PA1, LCD_D2 ---> PA2, LCD_D3 ---> PA3, LCD_D4 ---> PA4, LCD_D5 ---> PA5, LCD_D6 ---> PA6, LCD_D7 ---> PA7, 5V ---> 5V, 3.3V ---> 3.3V, GND ---> GND

I use this code: https://github.com/nopnop2002/STM32_TFT_8bit/blob/master/examples/GraphicsTest_240x320_SMT32/GraphicsTest_240x320_SMT32.ino

in STM32F103C8T6 header board serial port show this: :-( STM32_TFT_8bit Test! readReg16(0)=0x0 readReg32(A1)=0x0 readReg40(BF)=0xffff readReg32(D4)=0x0 readReg40(EF)=0x0 readReg32(FE)=0xfe readReg32(04)=0x0 readReg32(D3)=0x0 readReg16(0)=0x0 Device ID: 0x0 Width: 240 Height: 320 ... what is the problem, why my TFTLCD is only white ?!

please help me, Thanks so much

Please try the following sketch using UNO.

https://github.com/prenticedavid/MCUFRIEND_kbv/blob/master/examples/LCD_ID_readreg/LCD_ID_readreg.ino

Please tell me the result.

laserayaneh commented 6 years ago

Thanks so much for your replay.

this TFTLCD ili9325 work fine with AVR series, but I want work this TFTLCD with STM32 series.

almost I will test this source with Arduino Uno and STM32 header... I hope I can lunch with STM32...

Best wishes

nopnop2002 commented 6 years ago

There is a possibility that TFT you have isn't ILI9341.

So please change https://github.com/adafruit/TFTLCD-Library/blob/master/examples/graphicstest/graphicstest.pde

tft.reset(); uint16_t identifier = tft.readID(); Serial.println("identifier=" + String(identifier)); // ADD THIS LINE

And Execute this with UNO.

You'r TFT is not ILI9341. reg(0x00D3) 00 00 00 00 ILI9341, ILI9488 True 9341 set TFT-ID in this register.

And not ILI9325 reg(0x0000) 00 00 ID: ILI9320, ILI9325, ILI9335, ... True 9325 set TFT-ID in this register.

I can't find any information about [reg(0x0009) C4 C4 5A A6 00].

It's the same outward appearance, but mcufriend has a lot of variations. http://domoticx.com/arduino-shield-2-4-tft-lcd-touch/

Hi, I use this code on STM32F103C8T6 and show this results:

Hi, When I use this code: https://github.com/JoaoLopesF/SPFD5408/blob/master/examples/spfd5408_graphicstest/spfd5408_graphicstest.ino on my Arduino Uno, all thing is Okay and show "Found ILI9325 LCD driver" and its true.

Thanks so much

nopnop2002 commented 6 years ago

Thank you. I'll test your code.

laserayaneh commented 6 years ago

Thank you so much,

I am wait for your replay :-)

nopnop2002 commented 6 years ago

I tried your code.

My result:

Dummny Byte Read = 0 2nd Parameter Byte Read = 0 3rd Parameter Byte Read = 93 4th Parameter Byte Read = 41

Please see 8.3.23 chapter of this data seat.

Your TFT may be ILI9341. But register reading can't be done.

So please change your code.

https://github.com/nopnop2002/STM32_TFT_8bit/blob/master/examples/GraphicsTest_240x320_SMT32/GraphicsTest_240x320_SMT32.ino

void setup() { delay(1000); Serial.begin(9600); Serial.println("STM32_TFT_8bit Test!");

ID = tft.readID(); Serial.print("Device ID: 0x"); Serial.println(ID, HEX); ID = 0x9341; // -----> ADD tft.begin(ID);

laserayaneh commented 6 years ago

Hi,

I set ID = 0x9341 and ID = x9325...

but my TFTLCD ili9325 not work !

my TFTLCD show this results:

TFT LCD test - Read of the ID register Dummny Byte Read = D3 2nd Parameter Byte Read = D3 3rd Parameter Byte Read = D3 4th Parameter Byte Read = D3

Thanks so much

nopnop2002 commented 6 years ago

Your TFT is Unknown model.

Is it work this??
