How to set AUX Rising Edge Trigger on 6425E?
Hello,
I am using the ps6000a SDK with the 6425E scope and cannot figure out how to set a simple trigger using the AUX channel as a source to trigger on the rising edge of a square signal. We need channels A through D for data collection. This seems to work in PicoScope 6 so it should work in the API functions.
Here are the steps I took:
0. Before each attempt I opened the scope with 10-bits resolution and activated channels A through D.
1. I first tried ps6000aSetSimpleTrigger() but then realized this function cannot be called with PICO_TRIGGER_AUX for the source argument.
2. I then decided to a try setting an advanced trigger by calling ps6000aSetTriggerChannelConditions() with the action set to PICO_CLEAR_ALL and using following PICO_CONDITION Struct:
PICO_CONDITION_struct.source = PICO_TRIGGER_AUX
PICO_CONDITION_struct.condition = PICO_CONDITION_TRUE
This returns PICO_OK when called.
3. I then called ps6000aSetTriggerChannelDirections() with the following PICO_DIRECTION struct:
PICO_DIRECTION_struct.channel = PICO_TRIGGER_AUX
PICO_DIRECTION_struct.direction = PICO_RISING
PICO_DIRECTION_struct.thresholdMode = PICO_LEVEL
This return status code is 0x00000010 which is PICO_INVALID_CHANNEL.
I can't seem to get past this status code no matter which combinations of inputs I use. I even tried setting the trigger source on channel A and still get the same error.
I have some looming deadlines to meet so any help as soon as possible would be appreciated.
Thank You.

Hello,
Yes, I just gave it a try and I still get the same status codes and errors.
