Re: USB Host, what solution?

Note that STM32 core provide dwt api to help usage. ;)
And that delayMicroseconds use it when it is available.

Re: custom STM32L412KB board

You can use https://www.st.com/en/development-tools/st-mcu-finder.html to find the mcu which best fit your need. L412KB is supported, in fact all can be supported easily. The STM32 core is MCU oriented. Moreover the new core 2.0.0 will provide all the variant skeleton to ease board addition. About t...

Re: cant find stm32l4 board in boards manager

Yes that is normal.
As you could see on GitHub page (README.md) all the generic L4 supported are from 2.0.0 release. That's why you didn't have them with 1.9.0.
2.0.0 should be released this week.

Re: USB Host, what solution?

Currently no USB host is supported by the core. A PR introduced this for Mass storage but always a WIP and doesn't not covered HID but a least USB host library is now accessible.

Re: How to use HAL_UART_RxCpltCallback function

Which environment you used ? Arduino IDE ? Using HAL_UART_MODULE_ONLY is the correct way but it seems not take in account during your build. As you can see here https://github.com/stm32duino/Arduino_Core_STM32/blob/eaeb794028c5c36be184aa4f3b568a45f1768cd1/libraries/SrcWrapper/src/stm32/uart.c#L791 t...

Re: Weird hangs RFM69 + WeAct Blackpill V2

You can try to change some interrupt priority: https://github.com/stm32duino/wiki/wiki/Custom-definitions#change-interrupt-priority-values Mainly the USARt one, if the library print a lot of stuf... Seems it has been tested with the STM32duino core with Disco F407 as stated here: http://www.airspayc...

Re: [SOLVED] Maple_Upload.bat : EXCEPTION_ACCESS_VIOLATION

i think that java-loader.jar app's key use isn't quite USB DFU, but to send that DTR 1EAF 'magic' command to the core to trigger a reset. Right the biggest catch with c/c++ based compiles is, they are normally build with respect to a particular os and release. and is possibly even dependent on patc...
