Arduino for STM32

run the examples

yes, I ran an example. I was able to easily replace the displayed text, its color and position in the example. However, when I try to modify the code called in the example like this Serial.println(testLines(ILI9341_CYAN));
unsigned long testLines(uint16_t color) {
unsigned ...

by using constructor for hardware spi
Adafruit_ILI9341(int8_t _CS, int8_t _DC, int8_t _RST = -1);

Thank you, this really doubled the FPS.
After mega8 looks impressive.

Yes it really works! library

came up beautifully, thank you very much!
I used the following initialization command:

Adafruit_ILI9341 tft = Adafruit_ILI9341(PA4,PB1,PA7,PA5,PB10,PA6);

and it worked, the connection is as follows:

TFT_CS - PA4, TFT ...

please show me where can I get a library for working with my display using the SPI protocol?
This library http://www.rinkydinkelectronics.com/library.php?id=51 also does not work with the official STM core?

and what do we have? The SPI library requires the libmaple_types.h file from the Roger core version, which for some reason I can’t find in its core. The official core SPI library gives a compilation error:

C:\Users\����\Documents\Arduino\libraries\Adafruit_ILI9341_STM/Adafruit_ILI9341_STM.h:150 ...

SPI port 1, ok, I'll try it, thanks

it assume to use predefined hardware spi class

could you tell me which pins should be used for this?

not match the data type, but in all the manuals that I saw written appeal to the pin only by full name!


upd: in file variant.cpp (way^ appdata\local\arduino15\packages\stm32\hardware\stm32\1.8.0\variants/pill_f103xx) i find next:
PB_9, //D0
PB_8, //D1

Hi, I immediately apologize if I created the topic in the wrong section and ask me to send it in the right direction. In the STM32 topic recently, before that, I used the arduino mini for a long time, but in the current project I’m sorely lacking in speed for normal operation with a display based on ...
