Overview of I2C Bus The Inter-Integrated Circuit (I2C) protocol enables half-duplex serial communication common used with devices like OLED displays and gyroscopes. The bus consists of three lines: SCL (clock), SDA (data), and ground. OLED Display Control Architecture Hardware Layer OLED screens utilize the SSD1306 controller chip for operation ...

General Purpose Input/Output (GPIO) pins typically operate with in a logic voltage range of 0 to 3.3V. While certain inputs may tolerate 5V, output stages are strictly limited to the 3.3V supply. To control higher-power devices such as motors or relays, an external driver circuit must be integrated between the MCU pin and the load. Hardware Arc ...

Overview A ring buffer, also known as a circular queue, is a data structure that connects the end of a buffer back to the beginning to create a fixed-size, continuous circular memory space. This structure is ideal for streaming data scenarios where efficient memory reuse is critical. Common applications include inter-process communication, U ...
