![]() I have also provided a 5V power supply to both the sensor and the LCD. I have connected the DIN pin of the module with the SDA (PB5) and SCL(PB4) pin of the STM8S103F3P6 board. The following schematic represents the connections diagram of the MAX719 Dot Matrix Display Module with the STM8S103F3P6 development board. We will require the following components to perform the I2C communication on STM8S with MLX90614 I2C sensor.Ĭircuit Diagram to Interface the Dot Matrix Display Module with STM8S Using SPI ![]() You can check our tutorials on the STM8S Microcontroller where we have discussed on How to setup the Cosmic C compiler and we have covered the PWM, ADC, UART and I2C with the STM8S103F3P6 development board. So, let’s see what components will be required to perform the SPI communication on STM8S board. There are 4 GPIO pins that we will be using to perform the SPI communication as shown in the image below. ![]() In this tutorial, we will learn about the implementation of the Serial Parallel Interface (SPI) Communication on the STM8S103F3P6 board using an 8x8 Led matrix display module as the SPI device.
