how to link AD9959 and pico

[HaotianXu-hub]

i don't know how to link AD9959 and pico, I tried to test every pin with Oscilloscope. After that I tried to link them in the way of :CSB->GP8, SCLK->GP6, SDIO->GP19, IOUP->GP17,RST->GP4, GND->GND.Then ran the binary-tests.ipynb, I could see a strenge wave .I think i must do something wrong.

We do need to improve the documentation so the pin-out is more prominent. Thank you for the reminder!

In the meantime, I recommend you consult the breakout board (https://github.com/QTC-UMD/dds-sweeper/tree/main/dds-sweeper-board). You don't have to use these boards to use the firmware, but these are the boards we test with, and therefore they are guaranteed to have the correct pin-out. The KiCAD schematic is what you will be looking for.
