Arduino for STM32

Hello I would like to read analog inputs with a 16-bit ADS1115 shield with the i2c protocol on pins PB10 and PB11. First of all, I tried the ADS1115 shield with Arduino Nano, and it works correctly. I'm using an STM32F103C8T6. I have tried using the Adafruit ADS1X15 library without success. I have r...

You have chosen the board of the wrong core, according to the attached picture you selected a board from the Libmaple(Roger's) core. Which one should I choose? "Generic STM32F1 series"? Then use STM32CubeProgrammer to load the sketch? What is the difference? I'm not very knowledgeable abo...

I downgraded the Adafruit_GFX library to version 1.7.2 and checked the sample code, it didn't give me any problems. :) I uploaded the sketch to the MCU and it works perfectly !! : D Thanks! The pins to which I connected the I2C are PB6 (SCL1) and PB7 (SDA1). I have tried connecting to pins PB8 (SCL...

I downgraded the Adafruit_GFX library to version 1.7.2 and checked the sample code, it didn't give me any problems.

Tomorrow morning I will load the code in the board and verify that it works.
Thank you for your suggestion.

Hello. I'm trying to run 2 0.96 "(128x64 px) OLED displays model SSD1306 with my STM32F103C8T6 card. I use Windows 7, Arduino IDE 1.8.12, STM32 Cores 1.9.0 (from STMicroelectronics), 128x64 px I2C OLED display and AdaFruit Adafruit_SSD1306 library. I state that I view the testimonials with Ardu...

Hello.
I was very pleased to find that the forum has come back active.
I discovered this forum because I couldn't get the 2.4 "TFT to work and soon after it disappeared.
I am glad that I can learn new things with this forum;).
Bye.
