Stm32 Lcd 1602 I2C Hal. The HAL_I2C_Init() function included in the STM32 SDK will automatically read the highlevel parameters such as AddressingMode and will configure the I2C hardware accordinglyBelow is an overview of the main I2C configuration parameters passed to HAL_I2C_Init()Note that we have selected the 7bit addressing mode each I2C transmission.
STM32 HAL Drivers Examples HAL GPIO APIs HAL Detailed Function Description In the same manner there are lowlevel hardware drivers for almost all the hardware peripherals in the STM32 microcontrollers Including Timers ADC USART I2C USB DAC Comparators etc.

In this article I would like to talk about my experience connecting LCD displays to the STM32 microcontroller using the HAL library on the I2C bus I will connect the display 1602 and 2004 They both have a soldered I2C adapter based on the PCF8574T chip The debug board will be Nucleo767ZI and the development environment will be STM32CubeIDE.
STM32 HAL Library Tutorial – HAL Library Examples DeepBlue
The STM32 line of microcontrollers are a popular implementation of the ARM CortexM core from STMicroelectronics As with most microcontrollers almost all STM32 parts come equipped with 1 (or more!) I2C interfaces If you have not set up STM32CubeIDE with your Nucleo board you will need to do so following the steps outlined in this tutorial If video is your preferred medium.

Basically we are going to use the parallel connection between STM32 and the LCD itself LCD 16×2 can be connected in the parallel mode either using 4 data pins (LCD 4 bit MODE) or using all 8 data pins (8 bit MODE) In this tutorial we are going to use the 4 bit MODE to connect LCD with our microcontroller CONNECTION.
