Arduino for STM32

@Bakisha
Seems strange as PYn is the pin number while PY_n is the PinName all standard Arduino API uses pin number. Some few extra API use directly PinName.
it works for @mrguen as it uses the SPI.setXXX which handles both notations.


Well if you consider that "PA_10" might be different than ...

Frankly, I was far from the theory. I wanted to be coherent and use the #define in the Pin configuration table. Using the pin number was throwing a compilation error so I changed everything to pin names.

I finally got it working, after adding some Serial.println lines... so I suppose "things were going too fast !!!" :evil:

Indeed the graphic test is extremely fast. Here is the full code:

#include <Adafruit_GFX.h> // Core graphics library
#include <Adafruit_ST7735.h> // Hardware-specific library ...

Also I noticed that the microcontroller is not going out of the bootloader mode after downloading. I have to change BOOT0 from 1 to 0 and reset to enumerat the COM port and run the program (different from generic STM32F401RG)

@Bakisha I did not define anything more than the needed pins. I don't think it hurts. It was working like that on the STM32F401.

Yes, I added build_opt.h with -DHSE_VALUE=16000000

I use an external 16 MHz crystal. 16 / 8 * 168 / 2 = 168 MHz. The mcu is working and I can have a program run the Sketch also uses Serial that is displaying on the Serial Monitor.

Here is the clock config that I use in the sketch:

extern "C" void SystemClock_Config(void)
{
RCC_OscInitTypeDef RCC ...

I did not make a library, only testing a sketch with the code I provided. I am sorry it was some months ago and I was not into this until today. Now I have moved to STM32F405. Since these microcontrollers are very similar I thouht it would work without any change. But I spent my all day ...

Hello,

I am working on an application that uses SPI=SPI1 with alternate pins (MOSI=PB5, MISO not used, SCK=PB3) to communicate with a TFT screen and another SPI (SPI2) to communicate with an ADC.

I tested ok with STM32F401. I thought it would run the same on STM32F405. Unfortunately I was not able ...

Hello

What do you mean by

the "issue" you mentioned is a PR which is not merged as it request review.

How can I have this pin work normally?
