Re: I2C and ADS1115 communication problem with STM32F103C8T6

Great!! Now everything works. Thank you very much. This is the working code //#include <Wire.h> #include <Adafruit_ADS1015.h> //Use IIC2 interface // Modify the file C: \ ... \Documents\Arduino\hardware\Arduino_STM32\STM32F1\libraries\Wire\Wire.cpp line 106 as follows: TwoWire Wire (2); TwoWire WIRE...

Re: I2C and ADS1115 communication problem with STM32F103C8T6

While using this other form, the compiler finds no errors, but equally the problem is not solved. This is the code I use for the various tests: #include <Wire.h> //#include <SoftWire.h> #include <Adafruit_ADS1015.h> //SoftWire SWire(PB10, PB11, SOFT_FAST); // PB10, SCL - PB11, SDA //use IIC2 TwoWire...

Assuming you are using Roger's version of STM32duino, there is a function to remap the pins:
I am using Roger's version of STM32duino, and I edited the file STM32F1/cores/maple/libmaple/i2c_f1.c without success.

Re: I2C and ADS1115 communication problem with STM32F103C8T6

I use Roger's version of STM32duino. To avoid misunderstandings, this is what I read at compile time: D:\arduino-1.8.12\arduino-builder -dump-prefs -logger=machine -hardware D:\arduino-1.8.12\hardware -hardware C:\Users\Perito Industriale\AppData\Local\Arduino15\packages -hardware C:\Users\Perito In...

Re: I2C and ADS1115 communication problem with STM32F103C8T6

I connected the ADS1115 shield to the PB10 and PB11 pins and I did the schetch i2c_scanner_softwire first and then I tried to read the values sent by the ADS1115. Through the scanner you can see the address of the device as in the case of the hard wire, but when you want to read the values of the ch...

Re: I2C and ADS1115 communication problem with STM32F103C8T6

After several attempts, I managed to get the ADS1115 to work partially. I use the core maple, and a Chinese STM32F103C8T6 shield. With the I2C_scanner I see the ADS1115 address only from pins PB6-PB7 and PB10-PB11, while nothing is detected on the pins PB8-PB9. The schetch I wrote on the base of the...
