Logic analyzer is an indispensable device in design. It can quickly locate errors, find and solve problems, especially when analyzing timing, such as 1wire, I2C, UART, SPI, CAN and other data, the application of logic analyzer to solve problems is very fast..
Plug the DuPont cables into the logic analyzer interface one by one. After the DuPont cables are inserted, they will be divided into 2 rows. The upper row of 5 logic analyzers corresponds to the silk screen on the left side of the shell, and the bottom one row corresponds to the silk screen on the right. Before testing the signal, please connect the GND channel of the logic analyzer to the GND pin of the board, otherwise the measured data will be unreliable..
If the logic analyzer works at 24M, the USB device must not only provide a 24M communication rate, but also must ensure that other devices occupy USB resources before the 4 buffers are filled. For these reasons, the logic analyzer cannot always work at the sampling frequency ....
