Arduino for STM32

For timer (interrupt only): HardwareTimer *timer = new HardwareTimer(TIM5); uint16_t prescalefactor = 0xFF; volatile uint16_t timer_value = 10; volatile bool timer_tick = true; void overflowISR() { timer_tick = true; } void setup() { timer->pause(); timer->setPrescaleFactor(prescalefactor); timer->s...

Sorry, my mistake. Just because you posted in forum's section for STM32 core , i assumed you want to use STM32 core. Anyway, you are right, it doesn't matter what timer are you using, since it is only for interrupt, not for PWM on a pin. SPISettings settingsA(70000000, MSBFIRST, SPI_MODE2); will set...

- Better re-check pinout for you board. On STM32F401CC TIM5 is connected to PA0/1/2/3. TIM2 is alternate function, not default. You could compare to bluepill: F401 https://github.com/stm32duino/Arduino_Core_STM32/blob/master/variants/STM32F4xx/F401CC(F-U-Y)_F401C(B-D-E)(U-Y)/PeripheralPins_BLACKPILL...

I can confirm that it's working using D2/D3/D4 (and 2/3/4) instead of PA_2/PA_3/PA4.

I guess i've just being lucky.
What about port B pins? PB1 should work without underscore? I can't test that at the moment.

I just checked (on WeAct STM32F411CE), library version 1.7.3 .

It works if i use: It doesn't work with: I don't know why it is behaving like that...

I had problems with those boards too. After some time i figure out that my problem was actually fingers touching nearby pins and it wouldn't enter in bootloader. Pressing those buttons with two pens solved my issue. I never measured resistor values for pull-up resistors on reset and boot pin. Maybe ...

There is a sketch on https://github.com/perz/irNEC/blob/master/irNEC.ino

Not a library, but should be easy to integrate.
Tested on STM32F103C8, ST core.

fpiSTM I don't think i has anything to do with SPI. If called by hardware SPI, Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST); then it only needs #define TFT_DC PA_3 #define TFT_CS PA_4 #define TFT_RST PA_2 to be able to work (example sketches from library). I can't say why, i'm jus...

Actually, this thread helped me finally figure out why my ST7735 wasn't working so far on my STM32F411CE with Adafruit library: Working: #define TFT_DC PA_3 #define TFT_CS PA_4 #define TFT_RST PA_2 #define TFT_SCLK PA_5 #define TFT_MISO PA_6 #define TFT_MOSI PA_7 Not working: #define TFT_DC PA3 #def...

When using // Redefining the SPI pin mapping to use alternate pins PB3/PB5 const PinMap PinMap_SPI_MOSI[] = { {PB_5, SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)}, {NC, NP, 0} }; why there is no {PB_15, SPI2, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI2)}, {PC_3, SPI2, S...
