In industrial production environments, it is often necessary to collect operational parameters of devices, such as power, temperature, pressure, and flow, through various sensors. The signal outputs collected are generally 4-20mA/0-10V 485 signals, which cannot be directly read by software platforms. Therefore, they need to be converted into TCP/IP signals. Devices that can achieve this … Read more
In today’s low-end digital communication applications, we frequently encounter IIC (Inter-Integrated Circuit) and SPI (Serial Peripheral Interface). The reason is that these two communication protocols are very suitable for short-distance, low-speed communication between chips. Philips (for IIC) and Motorola (for SPI) developed these two standard communication protocols based on different backgrounds and market needs. IIC … Read more
Linux has stormed the embedded systems market. According to industrial analysts, approximately one-third to one-half of new 32-bit and 64-bit embedded system designs utilize Linux. Embedded Linux has demonstrated advantages in many application areas, such as SOHO home networks and imaging/multifunction peripherals, and has significant potential for leapfrog development in areas like (NAS/SAN) storage, home … Read more
