Re: Firmware update through Ethernet

My ArduinoOTA library still doesn't have support for STM32, but you could try the upload over SD card with the SD bootloader. Use the ATmega_SD example. https://github.com/jandrassy/ArduinoOTA https://www.stm32duino.com/viewtopic.php?f=67&t=144 I work on testing it, but I can't make my Blue Pill rel...

Re: Just another bootloader

With SD bootloder OTA update should be possible.

Re: LCD i2c for STM32 with ArduinoIDE.

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

Re: Maple DFU Bootlader 2.0 upload code

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

Re: STM32F103 Ethernet library?

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...

No laptop required, but a blynk server. Does the server run on the STM board?
Blynk server is in cloud. Who knows on what does it run there

Re: Interfacing SD Card module with stm32f103c8t6 in Arduino IDE

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
