New ContributorCyclone IV E implementing SPI
I'm using EP4CE10 as a SPI Master to control LMX2820, then find the control words are not written correctly. Does the I/O pin selection and configuration has special requirement?
Hi,
Regarding the Pin Out, for your device is:

We do not have any example on SPI for Cyclone IV.
Maybe you could check these out, see if it helps:

Regular ContributorHi,
Could you share the Quartus design?
Have you tried to do a signal tap to see if the output are as expected?

New Contributorsignal Tap II from Quatus indicates the timing is right. I'm switching to STM32H7 for another try. The STM32F1 worked, but SPI baud-rate is too low and ADC sampling rate is not enough.
