Arduino for STM32

It's there - STM32CubeProgrammer (SWD) = ST-Link.

If you run the I2C scanner program in a loop, you should see a good bit of activity on SCL and SDA with your scope. Could the problem be the 10K resistor in series with the ADDR pin? The data sheet says to connect ADDR to VDD, VSS, SDA, or SDL but I didn't see any mention about a series resistor. Th...

See https://github.com/stm32duino/wiki/wiki/API#i2C . ... Redefine I2C pins Because they are defined as WEAK, you can redefine them in your sketch file instead of changing values in the PeripheralPins.c file. You can also enable/disable the internal pull-ups with the second parameter of STM_PIN_DATA...

All of those connectors and no SWD pins? I have a commercial STM32F103VET6 board that I program using either a ST-Link dongle or a USB/Serial adapter connected to USART1. I never could get any bootloader stable enough to be useful. The ST-Link is the way to go. The code uploads in seconds and no foo...

I saw this video when it appeared on my RSS feed last Sunday. It was a pretty good overview. Note that 8-bit uCs are not dead and are an excellent choice for some projects. True, I have a tube of ATTiny85s that are quite useful for small projects. It is surprising at the amount of code that will fit...

You can find this board pretty much everywhere That's true but at the moment for the USA, Amazon is about $3 less than eBay. Aliexpress search has been broken for a while (slide to verify then error, with multiple browsers, with and without private browsing, with and without VPN running). Free ship...

Assuming core 1.9.0 and a F103 board: HardwareSerial Serial1(PA10, PA9); HardwareSerial Serial2(PA3, PA2); HardwareSerial Serial3(PB11, PB10); void setup(){ Serial1.begin(9600); Serial2.begin(9600); Serial3.begin(9600); } In the options, select USART enabled, no generic serial. Names Serial1, 2, 3, ...

Try this:

Move MyTim->setPWM() to setup.

Inside loop, call
MyTim->setCaptureCompare(channel, dutycycle, PERCENT_COMPARE_FORMAT)

I would keep dutycycle in the range of 1 to 99, avoiding 0 and 100.

Jumper PB0 to PB1. #include <SoftwareSerial.h> #define mySerial SerialUSB SoftwareSerial swSerial(PB1, PB0); void setup() { mySerial.begin(9600); swSerial.begin(9600); } void loop() { for (int i = 0; i < 6; ++i) { swSerial.print("hello\n"[i]); if (swSerial.available()) { char ch = swSerial...

I tested a GPS module connected to PB0/PB1 with SoftwareSerial on a 407 board. It is working fine, printing the NMEA messages from the module. #include <SoftwareSerial.h> #define mySerial SerialUSB SoftwareSerial gpsSerial(PB1,PB0); void setup() { mySerial.begin(9600); gpsSerial.begin(9600); } void ...
