EtherCAT, as an efficient fieldbus network technology, relies on a high real-time operating system to fully demonstrate its real-time performance. This article takes the ZMC600E as an example to test system real-time performance and analyze operating system jitter data. ZMC600E EtherCAT Master Controller is a new generation intelligent bus-type controller developed by Guangzhou Zhiyuan Electronics … Read more
1. Basic Knowledge of JTAG JTAG stands for Joint Test Action Group and is the IEEE 1149.1 standard. The advantage of using JTAG is that it allows integrated circuits to be tested on a PCB through boundary scan. In the ARM7TDMI processor, JTAG can directly control ARM’s internal bus, I/O ports, and other information for … Read more
