Hello,
Debugging background: The cascading data acquisition demo comes from SDK4412 in DDM mode, and the data volume should not change due to the increase in the number of transmitting antennas. A self-made cascading board is designed according to the official website schematic diagram.
We encountered an issue with the waveform configuration when debugging the data acquisition program,
When both of our radar antennas are transmitting (6 rounds), the pulse interval time can only be set to a very short time, which is basically 8us or less,
For example, 3us, but we would like to freely configure this time, such as 65us and other times, as follows. However, in this case, we do not have any data sent from LVDS.
This issue also exists when debugging the cascaded software package applied for. When the waveform configuration idleTime is relatively large, it will quickly hang up after the radar is started.
A single radar has 3 transmitters, while the other does not transmit, allowing for a large idle time and data acquisition.
May I ask, what is the possible reason for this question? Is there a similar issue with the official cascading board data collection debugging? Have you ever tried a higher value for idle time?
