Weird problem that I’m having is that when I send a byte out on the SPI Tester (the Excam Labs one), I can’t see any data coming off the 6 pin connector. This is using the spicl.exe command. I wrote a little batch file to loop sending a byte of data. This Excam device gets the data, displays it but nothing comes out to the 6 pin connector.
Anyone with much experience with this Excamera Labs device shed any light?
While I haven’t used the Excamera device, if you intend to do more projects like this where you aren’t confident your communication peripherals are behaving themselves, a Saleae is invaluable. The software is a million times better than a little LCD, and it can record for hours (days even? your RAM capacity and the signal density is the limit) and also analyse pretty much any other protocol under the sun (i2c, serial/UART, Modbus are ones I’ve used)
I’d give the software a look and open a demo capture to see if you like the workflow, and start saving if you do (I understand that students don’t usually have the cash to throw at test gear, but the Logics are really worth it)
It can’t send data, but getting a microcontroller like a Pico to do that with high-level libraries is fairly fast.
