Arduino for STM32

With SD bootloder OTA update should be possible.

how is it related to STM32 Arduinos?

use an Arduino library. they use the Wire library which has the same API on all platforms

you don't need boot0 HIGH for programming with a programmer. the jumper is for ROM bootloader listening on Serial. did you return the jumper to LOW position?

and then there was this problem viewtopic.php?f=59&t=218

yes. it caused some confusion. thank you

I'm in the initial stages of selecting a processor for a wired ethernet project. I'll be using the STM32 Core. My supported choices so far are the F767 + external PHY, or the F103 + Wiznet5500. For the F767 the official STM32Ethernet library is clearly the one to use, but what is recommended for us...

Blynk server is in cloud. Who knows on what does it run there

sorry, but this forum is about STM32 dev boards used as Arduino. you use mbed

this is a SD card adapter with logic level conversion and 5 V powering. but STM32 is 3.3 V and SD card is 3.3 V device.
I don't recommend to use it. wired to 5 V VCC it could output 5 V on MISO and the MISO pin on Blue Pill is not 5 V tolerant

in Tools menu the Roger Clark's core boards are in "STM32duino section". The STM core has only "STM32" in the title. If you installed with Boards Manager you can look in Boards Manager, what boards package is installed.
