C# to visualize a digital signal like MDA, CGA and EGA using an USB logic analyzer | ||
|
||
It is loosely based on the sigrok2EGA project and uses the hardware connections defined there (see at the end). | ||
|
||
If started without arguments, it tries to start sigrok in 24Mhz mode. Currently the sigrok location is hardcoded here: | ||
"C:\Program Files\sigrok\sigrok-cli\sigrok-cli" | ||
|
||
It can also be started in a CMD window with the "-" argument and accepts an 8 bit data stream as stdin. ("myprogramm | CGATest -"). | ||
