Hi, Hoan,
Unfortunately, for LPC43xx, there is not configuration tools to configure the HSADC module of LPC4370. The MCUXpresso tools includes configuration tools, but the tools does not support LPC4370, the LPC4370 is a bit old.
This is an unofficial code for the HSADC plus DMA, pls refer to it.
Hope it can help you
