Arduino for STM32

Here is a snippet from one of my projects with a 60khz square wave output on PA6; // set timer 3 to 60KHZ square wave on PA6 - T3C1 HardwareTimer pwmtimer(3); void setup() { pinMode(PA6, PWM); pwmtimer.pause(); pwmtimer.setPrescaleFactor(1); pwmtimer.setOverflow(1200 - 1); // 72MHZ / 1200 = 60KHZ pw...

by Juraj » Mon Mar 23, 2020 1:07 am use an Arduino library. they use the Wire library which has the same API on all platforms The "hello world" example from https://github.com/johnrickman/LiquidCrystal_I2C compiles without error for the STM32L476RG board. Sketch uses 14116 bytes (1%) of program sto...

If you want to use the PinName (PA_5) you will need to convert to a DigitalPin. pinMode(pinNametoDigitalPin(PA_5), OUTPUT); Then you can use the digitalWriteFast function that takes a PinName as a parameter: digitalWriteFast(PA_5, HIGH); delay(500); digitalWriteFast(PA_5, LOW); delay(500); or simple...

Arduino 1.8.12 on Linux, STM core 1.8.0.
For a small program it takes 22 seconds to compile the first time.
After adding or deleting a line, recompiles take about 3 seconds.

Multiple LEDs are blinking and USB serial is saying 'hello world.'
It took about 15 minutes to get it working. Half of that was figuring out where to connect the wires from the ST-Link.

Flash and ram are reporting the correct values on upload.

Thanks for posting the link to the VET6. I have a board with a STM32F103VCT6 that I never got around to creating a variant. It looks like the main difference is that the VCT6 has 256K flash instead of 512, and 48K ram instead of 64. All the pin names seem to be the same at first glance. Hopefully al...

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 ------------------------------------------------------...
