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

Re: What core am I using ?

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.

Re: Juraj

I tested my WiFiEspAT and StreamLib with Blue Pill with STM32 and with STM32duino boards packages. Both work. Some small adjustments were necessary for Roger Clark's core in WiFiEspAT library (some fake _P functions and include itoa.h, because it is not in Arduino.h ). And I retested the UIPEthernet...
