On February 18, Krste Asanovic, the chairman of the RISC-V Foundation, unexpectedly published a blog on their official website titled “RISC-V is not an ‘open-source processor’”. Upon seeing the title, I was taken aback, thinking, “Huh? You’ve been promoting open-source for years globally and in China, and now you’re coming out to contradict yourselves?” To … Read more
Source: Semiconductor Industry Observer With the support of technical heavyweights, RISC-V is continuously growing, but it also brings challenges: encouraging CPU designers to maintain consistency and avoid the kind of fragmentation that occurred with MIPS and Android. In light of this, RISC-V International, which coordinates the development of the open-source instruction set architecture (ISA), has … Read more
Introduction SD card reading and writing refers to the process of microcontrollers reading and writing to SD/TF cards. The SD card is a low-voltage flash memory product that has standard MMC/SPI operation modules. For the MMC operation mode, the reading and writing speed is fast, but it has more control signal lines and is more … Read more
Dear friends, hello everyone! Today, the topic we are going to learn about is the serial communication protocol of microcontrollers (MCUs). This content is quite important and relatively professional, but I will try to explain it in a simple and understandable way. First, let’s see why we need serial communication? Communication is the Basis of … Read more
In job interviews, the characteristics of communication protocols are a common question. Below is a summary of the basic characteristics of several common communication protocols: Communication Protocol Sync/Async Serial/Parallel Full-Duplex/Half-Duplex/Single-Duplex Main Features I²C (Inter-Integrated Circuit) Sync Serial Half-Duplex Multi-master and multi-slave, uses SDA and SCL lines, supports 7-bit and 10-bit addresses, low speed but suitable … Read more

Author/Original:Wolong Association Group Member Diandian I2C Timing Stretching Issue! In hardware design, it is inevitable to deal with various interfaces, commonly used ones such as I2C, UART, SPI, and Ethernet. Each type of interface has its own requirements in design, but even the simplest things have their unique aspects. Today, we will discuss the timing … Read more
Programming and Reading Demura Data in AMOLED Display Driver Chip YANG Guozhong, ZHANG Jie, CHEN Jie Abstract — The Demura data to be used in the driver chip of AMOLED display need to be saved in the non-volatile memory outside the driver chip. After the driver chip is powered on, the data should be read … Read more
SD The SD card (secure digital card) is a low-cost, non-volatile storage card format developed by the SD Card Association (compared to RAM, data on an SD card is not lost when power is off); With the rapid development of electronic technology in this century, the demand for such medium-sized, energy-efficient, and space-saving storage devices … Read more
▲Click the card above to follow for more information▲ 1IIC IIC (Inter-Integrated Circuit) bus is a two-wire serial bus developed by PHILIPS for connecting microcontrollers and their peripheral devices. The I2C bus transmits information between the bus and devices using two lines (SDA and SCL), allowing for serial communication between microcontrollers and external devices, or … Read more
