Arduino for STM32

Also for a STM32 must be a default setting, so after power up program recognizes a SD-card at the correct SPI-pins or a sensor at SDA/SCL. And the datasheet is not the right place! Of course I looked into chapter 4 and there in table 8. In column "Pin name (function after reset)" there is ...

https://www.st.com/resource/en/application_note/an4899-stm32-microcontroller-gpio-hardware-settings-and-lowpower-consumption-stmicroelectronics.pdf Nice document, but not my question. If I buy a Arduino UNO I can see printed on the board RX, TX, SCL, SDA. So I know where I have to connect a RS485-a...

Sketch has not been updated after SPI rework. I changed sketch to new functions and used a WeAct Studio BlackPill STM32F411CEUS, pin numbers are from their pinout graphic. LED on PA13 is connected to +3.3V, so it shines, when output level of PA13 is LOW. So I placed defines for LED_ON and LED_OFF a...

My system: Windows 10 ArduinoIDE 2.3.2 Arduino core for STM32 MCUs 2.7.1 There is a test-sketch named SPI_loop.ino inside examples https://github.com/stm32duino/STM32Examples/blob/main/examples/NonReg/SPI_loop/SPI_loop.ino The code from line 50 to 53 is: SPI.begin(CS_PIN); for (uint8_t received = 0;...

There is an issue in your setup as you used: Wire.setSDA(PA5); Wire.setSCL(PA4); But they are not I2C pins based on the PinMap_I2C_SDA array you provide. The "PYn_R" pin is remap pin that's all but when you remap some other "PYn" pins will not be available. @fpiSTM: I'm still in...

Let me start with the last part: Finally I tried it on PB6/PB7, but the I2scanner.ino tells me, there is not I²c-device. Do you have Pullup on each I2C line ? I took out a STM32F411CE board to compare. I uploaded the i2scanner.ino via STLink. Then I connected A9/A10 to an USB-TTL-adapter to see outp...

Do you read my posting???

What drives me crazy at the moment is I²C :cry: Generally information is spread over several places. I know there are STM32Examples, but there is nothing about I²C. Instead you have to look at Arduino_Core_STM32/libraries/Wire/ And for some additional information, you have to look at: https://githu...

- DAPLink is for MBed , and will work for other IDEs , but for Arduino , I really fear it won't work , so far I think the problem is, that ArduinoIDE started with 8bit microcontroller. And debugging is a new topic since IDE 2.x comes out. In documentation I found: Arduino® boards with a SAMD microc...
