Arduino for STM32

See http://gammon.com.au/interrupts section "Hints for writing ISRs".

You can simplify the led line to If led is 0 then 1 - led = 1.
If led is 1 then 1 - led = 0.

If using libmaple, you may need enableDebugPorts(). See https://github.com/rogerclarkmelbourne/ ... sh_debug.h

You might want to try the STM32 Cube programmer for your stlink. Test setup - STLink connected to SWD and power pins on blue pill. Both boot jumpers = 0. USB not connected. ./stm32CubeProg.sh 10 /tmp/arduino_build_151098/sketch_jan25a.ino.bin -s ------------------------------------------------------...

The STlink v2 with STlink utilities doesn't not allow me to re-flash without using reset pin I'm using the STM core v1.8.0 without any bootloader. There are three wires connected from the ST-Link adapter - SWDIO, SWCLK, and GND. Power is via the USB port. Both boot jumpers are at 0. Uploading the b...

It was more of a puzzle to me than an actual problem. I'm reviewing the fix on Github to understand how you solved it. Thanks.

I saw this come across the RSS feed a short while ago: We’re excited to announce that Arduino IDE 1.8.11 is here! In addition to the usual load of bugfixes and small improvements under the hood, the latest version includes: Improved support for Mac OS X (the app is now notarized and strictly follows...

For "hello world" using the pin names gives the smallest code size: HardwareSerial Serial3((uint32_t)PB11,PB10); // 8528 bytes flash - 676 bytes ram HardwareSerial Serial3(USART3); // 8452 bytes flash - 676 bytes ram HardwareSerial Serial3(PB_11, PB_10); // 8352 bytes flash - 676 bytes ram

HardwareSerial Serial3(USART3); // compiles HardwareSerial Serial3(PB_11, PB_10); // compiles HardwareSerial Serial3(PB11, PB10); // error: call of overloaded 'HardwareSerial(int, int)' is ambiguous All three examples work if the board type is changed to a blue pill. Casting PB11 to an int lets it ...

Instead of configuring a timer, you can use HAL_SYSTICK_Callback() which fires every millisecond. See viewtopic.php?p=644#p644 for blinky example using systick.
