Arduino for STM32

@ GonzoG thanks for the advice. But if I am not wrong thats what I already do. I already do have the "STM32CubeProgrammer" installed and use already the "STM32CubeProgrammer (DFU)" upload method. As far as I know the BlackPill already has a hardware bootloader integrated, so I did not toutch that, ...

It looks like OLED controller might need more time to start then STM. Try adding delay before initializing display.
I also recommend u8g2 library. It's faster than adafruit and much more fonts. You can also create own font quite easily.

The fastest are LCDs with parallel interface, but they need up to 20 MCU pins.
The higher resolutions the longer it takes to send 1 frame to LCD.

If you reset F4x1 black pill into DFU mode (hardware USB bootloader) then it won't show as a COM port. It works in different mode. You need to select "STM32CubeProgrammer (DFU)" as upload method and have STM32CubeProgrammer installed. There is HID bootloader for F411 black pill: https://github.com/S...

Hi,

I have same problem about reading stm32f103 internal temp sensor values. I always get minus values from serial port. Which code did you use to solve this problem?
Thanks.

He got those negative values on fake STM chips. They are similar but not the same so some things might not work.

Yes, you need to disable USB support.

Yes, all pins are interrupt capable but you can use only 16 interrupts, so only one pin with same number can be used (eg. you cannot use interrupts on PA1 and PB1, only on one of them)

They are not only for USB.
But you cannot connect board with USB data cable (only power, no data wires) or connect it to power source that does not have data wires connected.
And do not enable USB in board settings.

1. the lower the voltage the lower current consumption. (STM32L476 datasheet pages from 124) 2 and 3. There is internal voltage reference (datasheet page 122) but not like Arduino. You cannot switch ADC reference voltage in program. An example how to use internal voltage reference to measure ADC Vre...

Are you sure that ArduCAM library supports STM32 MCUs ??

Sir, could you please integrate this code with this: #include <RTClock.h> #define buttonPin PA10 RTClock rtclock (RTCSEL_LSE); // initialise int timezone = 8; // change to your timezone time_t tt, tt1; tm_t mtt; uint8_t dateread[11]; bool dispflag = true; const char * weekdays[] = {"Mon", "Tue", "W...
