I'm a newbie. I just started to use AD and encountered some minor problems. The book I bought has some scattered device diagrams and schematics. I want to organize them and make a library, but I can't...
Does SPI have a clock signal as long as it sends data? Now there is data sent out, but there is no clock signal output. I have set it up like this: master mode, SDO controlled by the module, 8-bit tra...
There are two 2407 chips on a board, 5cm apart. If I directly cross-connect the CAN transceiver interface, is it feasible? Do I need 82C50 between them? I have used SPI and SCI, and I want to try CAN....
Regarding the dynamic display of the oscilloscope, to display a 10M bandwidth, no evaluation rate is required, no other processing is required, just sample and display the waveform. So can a crystal o...
