DE10-NANO - NIOS+ADC+DMA+ONCHIP MEMORY+HDMI on Platform Designer

Hello everyone, I'm new with FPGA, NIOS2 and Platform Designer and I have the DE10-nano board. As a project, I want to make a digital oscilloscope (a simple one at first). 

 

I have Quartus Prime Lite Edition 17.1 and Nios II SBT. 

 

The project consists on the following steps as I see it: 

1. Sample 12-bit data from ADC channel 0. 

2. Get the sampled data from the ADC to the on-chip memory through a DMA. 

3. Show on LCD connected through HDMI a waveform made from the data saved on the on-chip memory. 

 

Everything is controlled from a NIOS II Processor. 

 

 

I've been using the ADC demonstration provided by terasIC to sample data from channel 0 (only one channel) successfully. 

 

I tried adding a DMA controller and a On-chip memory to the Platform Designer to get all the sampled data from the ADC to the memory without success. 

 

If someone can shed some light I would really appreciate that. 

 

Hope I didn't miss any important information. 

 

Thank you very much in advance

Without seeing your design or details on what's not working and what troubleshooting you've tried so far, it's hard to help you out.
