Is there any reason why the MAX 10 ADC control core command_ready output is always low and never goes high even though I'm not giving it any sample to convert?
This is from the MAX 10 ADC User Guide: Command The ADC control core asserts ready when it is ready to perform a sample conversion. The ADC control core only accepts one command at a time. The control core releases ready when it completes processing current command and prepares to perform the next command. Once the ADC control core asserts "cmd_ready=1" to acknowledge the current command, the Sequencer core provides the next valid request within two clock cycles. If the next valid request comes after two clock cycles, the ADC control core perform non-continuous sampling.Link Copied

Hi,
1.How you have checked (elaborate steps you followed and about the design)? 2.Are you using development board or custom board? 3.Have tried with example code? https://cloud.altera.com/devstore/platform/?acds_version=16.0&family=max-10 Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation)- Mark as New

Hello,
1. I've checked using signal tap by observing the data going through the nodes; it shows zeroes. 2. I am using a custom board with the MAX10 chip 3. I have tried code that works on the dev board but when flashing the same code on the custom board, nothing shows up. --- Quote Start --- Hi, 1.How you have checked (elaborate steps you followed and about the design)? 2.Are you using development board or custom board? 3.Have tried with example code? https://cloud.altera.com/devstore/platform/?acds_version=16.0&family=max-10 Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation) --- Quote End ---- Mark as New

Hi,
1.Have tried to load simple program(switch->led)? 2.Can you probe at vref pin with input and share the images(check the input and vref of Max10 ADC) Can you share the schematic screen short of configuration sheet and ADC interface with filter circuit.
