Serial Communication Protocols UART (Universal Asynchronous Receiver Transmitter)： An asynchronous serial communication protocol that does not require a clock signal, commonly used for simple point-to-point communication. SPI (Serial Peripheral Interface)： A synchronous serial communication protocol, typically used for high-speed communication between microcontrollers and external devices such as … Read more
As many may know, Proteus is an EDA software that supports the simulation of microcontrollers. It has previously been used to simulate 51, AVR, PIC, MSP430, etc. Over time, it has gradually added support for Arduino, Raspberry Pi, and STM32. In the latest version (v8.17 sp4), Proteus has started to support MicroPython simulation. Below, I … Read more
Submitted by Curious Bin, thank you~ Recently, while learning about the Raspberry Pi, I encountered a problem when driving the OLED screen, which was display issues. After two days of troubleshooting, I discovered that the driver chip for this OLED is not SSD1306 but SH1106. Therefore, using the Adafruit_Python_SSD1306 library results in display issues. There … Read more
