MCU stands for Microcontroller Unit, which is commonly known as a single-chip microcontroller. It reduces the CPU’s frequency and specifications appropriately and integrates memory, counters, USB, A/D conversion, UART, PLC, DMA, and other peripheral interfaces, even LCD driver circuits, into a single chip, forming a chip-level computer. This allows for different combinations of control for … Read more
With the development of technology, RS232 serial communication is still widely used in industry. However, in commercial applications, the USB to UART technology has gradually replaced RS232 serial ports. Most laptops no longer have serial ports. So, how can we achieve communication between a microcontroller and a computer? We only need to add a USB … Read more
Source: Semiconductor Industry Alliance MCU is the abbreviation for Microcontroller Unit, commonly known as a microcontroller. It reduces the frequency and specifications of the CPU appropriately and integrates memory, counters, USB, A/D converters, UART, PLC, DMA, and even LCD driver circuits onto a single chip, forming a chip-level computer for different application scenarios. MCU can … Read more
Serial ports (UART) are a very commonly used interface in embedded systems, but most modern computers lack hardware serial ports. Generally, serial ports are expanded through methods like USB to serial or PCIe bus expansion. USB to serial is a very common solution. Common USB to serial chips include CH340/341, CP2102, and PL2302. However, these … Read more
1. The SPI rate must not exceed 15M; exceeding this will result in serious bit errors. 2. If the reception method is interrupt-based, the SpicCR character length control bit determines the length of the interrupt. For a length of 8, with interrupt priority 1, an interrupt is generated for each byte received. For a length … Read more

Introduction SPI (Serial Peripheral Interface) is a synchronous serial interface technology introduced by Motorola. The SPI bus is physically implemented through a module called Synchronous Serial Port (MCU) on the microcontroller (PICmicro) connected to peripheral devices, allowing the MCU to communicate with various peripheral devices at high speed in a full-duplex synchronous manner. SPI The … Read more
1. What is SPI? SPI stands for Serial Peripheral Interface, a synchronous serial interface technology introduced by Motorola. It is a <span>high-speed</span>, <span>full-duplex</span>, and <span>synchronous</span> communication bus. 2. Advantages of SPI Supports full-duplex communication, simple data transmission rate. 3. Disadvantages There is no specified flow control and no acknowledgment mechanism to confirm whether data has … Read more
UART, I2C, and SPI are the three most commonly used communication protocols in microcontroller systems. In this lesson, we will learn about the remaining SPI communication protocol. SPI stands for Serial Peripheral Interface. As the name suggests, it is a serial interface for peripheral devices. SPI is a high-speed, full-duplex, synchronous communication bus that typically … Read more
Hello everyone! Through our previous lessons, we have gained an understanding of how to use the ICD2 emulator and enhanced PIC development board. We have learned how to control resources such as LEDs, relays, buzzers, buttons, seven-segment displays, RS232 serial, stepper motors, and temperature sensors with microcontrollers. You must have felt the ease of use … Read more
