How to use a new digital oscilloscope for microcontroller development?
During the development of single-chip circuit, generally speaking, the components used and the chip itself have no problem. The problem is often come from the difference between them. The common bus is SPI, I2C, USB, LIN. The CAN, 54621A and 54621D oscilloscopes themselves support the triggering of serial signals, which can directly debug the communication on the serial bus. In addition, if you use DSP and MCU to develop the board, it may involve software and hardware joint debugging. At this time, you can use the digital logic channel of the 54621D to connect to the control line or data and address lines to determine whether the circuit can work normally under certain operating conditions or subroutine operations. Moreover, the memory depth of 2M points per channel is very helpful for analyzing the cause of the problem, observing long-term serial signals, observing the handshake timing, and so on. And its amplification function, the signal can be amplified tens of thousands of times to observe the details.
