I just received the SYH24A1 mmWave sensor and I’m wondering how to access the TTL reporting? I’ve read through the documentation, and the ST pin doesn’t seem to be returning any data on if a person is standing in front of the sensor. I’ve been looking at the Grove Doppler Radar wiki page (https://wiki.seeedstudio.com/Grove-Doppler-Radar/) and there appears to be a library to communicate to that chipset, but I don’t see any documentation on communications to the SYH24A1. Does anyone have any specs on communications with this chip?
Understand, is there any additional documentation for the chip?
This documentation appears to have the TTL frames and sample code: http://www.e-paper-display.com/SYH24A1%20datasheet%20V1.031ae.pdf?method=picker&flag=all&id=5401d713-3b28-4585-8584-36ac5f0e7a6c&fileId=1036&v=1.zip
Both documents on the Seeed website seem to link to the same introduction document.
Sorry, scratch that. The datasheet seems to be fixed now. Looks like I have the info to get the chip running.
