how to config adc and pdb for multiple channels

[Jimny]

Hello, I'm trying to modify the code from the official motor control demo.

The original demo uses 3 ADC channels, and I want to add an additional channel. Please see the table below.

original			expected
pin	adc channel	physical signal	pin	adc channel	physical signal
			PTA6	ADC0_SE2	i_ph_c
PTB1	ADC1_SE15	i_ph_b	PTB1	ADC1_SE15	i_ph_b
PTB0	ADC0_SE4	i_ph_a	PTB0	ADC0_SE4	i_ph_a
PTB12	ADC1_SE7	v_bus	PTB12	ADC1_SE7	v_bus

Here is what I have changed in processor expert.

add configuration for adc0_se2

add the associated pdb configuration

modify the adc peripheral configuration

modify the pdb peripheral configuration

You can find the archive file of the project in the attachment.

When I flash the binary file to the official demo kit, an error occurs, the software falls into  the default ISR.

Can anyone helps to find the root cause?

By the way, I have disabled the adc interleave and the test result is ok, the motor can run.

Hi@Jimny

     I double checked your configuration and found no problem, I suggest that you can try single-step debugging first, locate the step where the exception occurred, send me a screenshot of the picture, and then I'll check if there is anything I haven't considered arrive.

    You can also refer to the ADC pre-trigger configuration of the MCSPTE1AK144_BLDC_6Step,this routine can also be found in your install path,
