How to use the library with kernel Arduino_Core_STM32 with stm32f401ccu6? I have white dipslay. https://github.com/Bodmer/TFT_eSPI/issues/2682

Can I change the pins as in the originally mcu_friends?

#define TFT_CS   PB8  // Chip select control pin
#define TFT_DC   PB7  // Data Command control pin
#define TFT_RST  PB9  // Reset pin

#define TFT_WR   PB6  // Write strobe control pin 
#define TFT_RD   PB0  // Read pin

Can you please tell me how to initialize the display with the driver ILIL9342C?

nopnop2002 commented 1 year ago

It supports ili9342.

https://github.com/nopnop2002/STM32_TFT_8bit/blob/master/STM32_TFT_8bit.cpp#L640

i don't know ili9342c

brightproject commented 1 year ago

ili9342 supports it.

How set to ILIL9342? Library do it automatically? I use ili9342c in P023T009-V2 display 2 31_P023T009_cut But I cannot initialize correctly in any way. photo1685696835 (1)

Library do it automatically?

Yes. The driver is automatically determined here. It will works if you change here.

brightproject commented 1 year ago

he driver is automatically determined here. I soldered the display like this:


// common "MCUfriend" shields
#define TFT_CS   PB8  // Chip select control pin
#define TFT_DC   PB7  // Data Command control pin
#define TFT_RST  PB9  // Reset pin

define TFT_WR PB6 // Write strobe control pin

define TFT_RD PB0 // Read pin

define TFT_D0 PA0 // 8 bit parallel bus to TFT

define TFT_D1 PA1

define TFT_D2 PA2

define TFT_D3 PA3

define TFT_D4 PA4

define TFT_D5 PA5

define TFT_D6 PA6

define TFT_D7 PA7


Can I change in the library, or do I need to re-solder the pins?

You can change to these other PBs.

#define TFT_CS   PB8  // Chip select control pin
#define TFT_DC   PB7  // Data Command control pin
#define TFT_RST  PB9  // Reset pin

#define TFT_WR   PB6  // Write strobe control pin 
#define TFT_RD   PB0  // Read pin

This library uses the LL GPIO generic driver for controlling data pins. https://github.com/nopnop2002/Arduino-STM32-8bitTFT/blob/master/Arduino-STM32-8bitTFT.cpp#L134

The data pin is controlled using LL_GPIO_WriteOutputPort().

This function can change multiple IOs at once, but only IOs on the same port.

D0 to D7 can be changed by changing the following.

#if 1

Anything else cannot be used. And here are the other pins. https://github.com/nopnop2002/Arduino-STM32-8bitTFT#wirering-for-8bit-parallel-tft For Arduino_Core_STM32 Another code https://github.com/nopnop2002/STM32_TFT_8bit/blob/master/STM32_TFT_8bit.h#L62
