Arduino for STM32

One of Murphy's laws says: It works better if you plug it in. What I wanted to do, I have already done on BluePill and a separate ENC28J60. The netduino board was already intended for the archive box. Thanks to your answer, I gave Netduino another chance :) This time I decided to check HW. What was ...

What do you mean the problem could be with the timezone? What can I do or check in this case?

Hi all. Recently I successfully got ethernet running on a Netduino Plus 2. Thread from: https://www.stm32duino.com/viewtopic.php?t=1771 Now I have a problem with libraries for temperature sensors. I am trying to read the temperature from DHT22 and BME280, unfortunately without success, none of the l...

I changed the definition of HSE_VALUE in file stm32f4xx_hal_conf_default.h to 25000000. I stil have a problem with reading data from DHT22. The sensor is ok, I have tested it also with Arduino Leonardo and working well. Do I need change something else in clock setup? I noticed that the 1s time inter...

I'll have to dig into the clock setup. Using the millis() function to count the time, it turns out that 1s is actually 327ms. As a result, libraries that use the millis() and micros() functions (for sensor DHT22 and for RC5) do not work. Above proportion similar to 25000000 and 8000000 Should I chan...

I have never use the extern declaration.
Thank you - now I know how it works.

I read the SPI API manual and now everything is clear. https://github.com/stm32duino/wiki/wiki/API#new-api-functions-1 I shouldn't set SSEL pin. To sum up, to run ethernet on Netduino Plus 2 it is necessary: 1. set the clock extern "C" void SystemClock_Config(void) { RCC_OscInitTypeDef RCC...

Taa daaaaa!!! ping.png Thank you ozcar! At PA8 now I have beautiful sinus 25MHz. Success is but my satisfaction is about 95% :D At this time I had to change MISO to PB4 and CS to PC8 I have tried to do it like this in my sketch: SPI = SPIClass(PA7, PB4, PA5, PC8); SPI.begin(PC8); and also like this:...

I am stuck. I don't know how to use the STM32CubeMX tool. Anyone can support me configure the external crystal for board Netduino Plus 2?

Thank you. Probably this is what I am looking for but it's not working right now I read that the generic boards (I am using Generic STM32F4 series > Generic F405RGTx) have internal clock enabled so probably for this reason I have noisy wave on PA8. When I change second parameter to RCC_MCO1SOURCE_HS...
