I am using the LPC55s69 Dev kit
I need to configure the ADC to be triggered from an SCT. and then the DMA to copy the data to RAM.
I am using the SDK 2.6.3. if there is a sample code it would be really appreciated.
I was able to use the sample code from Nxp and can trigger the adc by a software trigger, and request the dma to do the copy to ram
functions used to do the conversion and copy data:
DMA_StartTransfer( &g_DmaHandleStruct ); /* Enable the DMA every time for each transfer. */ LPADC_DoSoftwareTrigger( LPADC_BASE, 1U ); /* Trigger the ADC and start the conversion. */
use an SCT as a HW trigger and have the dma automatically copying data into a Ram buffer.
Did anyone found solution and configuration to above problem for Hw trigger ADC?
