Arduino for STM32

so main main Arduino project is a heating power Triac based regulator consuming photovoltaic surplus. it reads data from inverter's datamanager over Modbus TCP, for monitoring it has Telnet server and web server with html, css and js. it uses Blynk cloud service to be accessible from anywhere with a...

I wonder. I see on this forum almost no threads about networking, Ethernet, WiFi, IoT, Web Server, OTA upload. I searched for a word WiFi and the treads returned showed no discussion about STM32 project with WiFi. Is it only the forum or are STM32 MCUs really used only for 'classic' projects with di...

@rikysuhendra , in old IDE you had Roger's core and in the new IDE installation you have the core by STM

I can step debug the Blue Pill in Eclipse Sloeber with ST-Link. I have in boards.txt in my_boards custom definitions (https://github.com/jandrassy/my_boards) this lines added BluePill128kswd.build.flags.optimize=-g -Og BluePill128kswd.compiler.c.extra_flags=-DDEBUG BluePill128kswd.compiler.cpp.extra...

I want to know what upload method did you select? your post doesn't contain the command

you do upload from IDE? what are your Tools menu settings? No, not yet. I am just using ST Cube Programmer at the moment, as I had the first error messages in the Arduino IDE (with the most recent core installed etc.) and then tried to reduce the impacts of other software. Blink didn't compile?

you do upload from IDE? what are your Tools menu settings?

I get this message if I try to upload but there is some other board? Is the port right?

PA9 and PA10 are 5 V tolerant

power the Blue Pill with 5 V from Serial Adapter.
did you reset after setting boot0?

I don't suggest update from SD card. The file to SD card is uploaded over network. Then the MCU is reset and the SD bootloader bootloads the binary. Of course better is to use the upper half of the internal flash to store the uploaded binary and then before reset copy it to final location in flash w...
