Despite the fact that dozens of industrial field bus protocols are still in use in the field of machine automation, industrial Ethernet is replacing many of these protocols with its superior characteristics. In earlier years, there were some basic open communication serial standards, such as RS232 and RS422/485. These standards, including Modbus, became the foundation … Read more
The CAN bus was born at the renowned Bosch company in Germany, arising alongside the development of the automotive industry. In the 1970s and 1980s, the automotive industry was booming, but several serious problems emerged: 1 There was no communication protocol in cars, making it difficult to support interaction between multiple controllers. Imagine trying to … Read more
Hello everyone, in this article we will talk about a common communication protocol in embedded development – the SPI protocol. However, today we will not discuss its basic principles, but rather explore a detail that many may not have noticed: the 4-wire and 7-wire versions of the SPI protocol. You might wonder, isn’t SPI just … Read more
