it worked, thank you.
just one observation: at first i followed your schematic and it did not work, so the i2c pins are reversed. the correct would be SCL to PB6 and SDA to PB7. after i inverted the pins it worked just fine

[vijaysulakhe]

Thanks...keep doing videos with different sensor, actuators, visual output etc.

How so you have connected the SDA to pin B6, but i look at schematic diagram of BluePill stm and there pointed B6 is an SCL pin!

[tacticalmisscalculation]

What LCD library did you used? Did you downloaded it form web or preinstalled one with Arduino?

[FCorporation]

how i might change i2c port in arduino ide code ? i want to connet SDA and SCL to ports B10 and B11

[muhammadfaisal-kobn]

Sorry, but i like point out the schematic that you are showing to us is wrong, by reading the pinout of the stm32 you supposed to connect SDA to pb7 and the SCL to pb6. You are showing us the opposite in the schematic you connected SDA to pb6 and SCL to pb7. Thank you.

[maulanawahyudi]

how to choose the pin from some of the i2c pins? does it work for all I2C pins? . And do we need to avoid other I2C pins for other purposes?

[prasadkatle]

Iam getting "LiquidCrystal i2C does not name a type" error

[fernandonicolasfortunati]

I need the link for download de library "LiquidCrystal_I2C"
