Some demos showcasing most of the functions are included in the download. This library will in this case fall back to a software-based, TWI-/I 2C-like protocol which will require exclusive access to the pins used. If you experience problems with pin-sharing you can move the displays SDA and SCL pins to any available pins on your development board. The library has not been tested in combination with the Wire library and I have no idea if they can share pins. If you are upgrading from an older version of the library you should read about the changes in the manual.
There are some important changes from v1.xx. This library will default to I 2C Fast Mode (400 KHz) when using the hardware I 2C interface. This library has been made to make it easy to use 128x32 and 128圆4 pixel OLED displays based on the SSD1306 controller chip with an Arduino, chipKit, ESP8266 or ESP32. Rather donate hardware directly? Then click here. Also, be sure to consult the STM HAL API documentation for detailed information on the available functions and their usage.And use any of my projects or libraries, and would like to encourage further development you can donate through PayPal here: Note that this is just a simple example, and your code may require additional modifications to work properly with the STM HAL API. Here's an example of what the converted code might look like: #include "stm32f4xx_hal.h" For example, you may need to change the data types or the way the code handles interrupts. Make any necessary changes to the code to account for differences between the Arduino and STM platforms.HAL_I2C_Master_Transmit(), HAL_I2C_Master_Receive()). Wire.beginTransmission(), Wire.write(), Wire.endTransmission()) with the corresponding STM HAL API functions (e.g. You'll need to replace the Wire library functions (e.g. Rewrite the I2C communication code to use the STM HAL API functions.
You'll need to set up the GPIO pins for I2C communication, configure the I2C timing parameters, and enable the I2C peripheral.
