I need to implement a voltage meter, for this, I want use an ADC with DMA.
I would like to implement this using the modules: CMP->PDB->ADC->DMA. A CMP module synchronizes a PDB that trigger a ADC that call a DMA. However, I am not able to configure the modules.
I am using Processor Expert and the components:
AnalogComp_LDD - Generate a pulse each 16.6ms;
Init_PDB - Works in continuos mode with CMP0_output as trigger pin. It´s generated a Trigger A output each 250us.
Init_ADC - Triggered by Trigger A and with DMA request enabled.
Init_eDMA - With just Channel 0 enabled and ADC0 as Channel Source. Data Source is ADC0_RA and Data Destination is a 128 bytes buffer.
What happens is that only some bytes are transfered to buffer and then nothing else is copied.
What I need configure for this works?
