How to use CTIMER4 as ADC trigger LPC55S28JDB100

[_Ferrari_]

Dear all,

I'm developing a project based on LPC55S28 processor

I have very simple question: How to use CTIMER4 as hardware triggerfor ADC conversion ?

I developed as simple software on LPC55S27-EVK board. If I use CTIMER0 as hardware trigger (ct0_mat3_out trigger 5)  it works. If I use CTIMER4 as hardware trigger (ct4_mat3_out trigger 9) it doesn't work.

Did you have similar problem ?

How did ypou fix it ?

Thank you for your help and cooperation

best regards

Hello @_Ferrari_ 

There should be some issue with your configuration code please check.

For example pin clock enable, pin configuration, and also check whether there is output of CTIMER.

Hello @_Ferrari_ 

First please confirm the CTIMER4 and output works well.
