Ticket Name: RTOS/TDA2: Communication between threads

Query Text:
Part Number: TDA2 Tool/software: TI-RTOS Hi, Run the following two threads at the same time 1. Capture -> Alg_FrameCopy (A15) -> Display_Video 2. DCAN model "D:\PROCESSOR_SDK_VISION_03_04_00_00\vision_sdk\apps\src\rtos\modules\dcan" I want to superimpose the radar data collected by DCAN in this link(Alg_FrameCopy (A15). How to get data received from DCAN to Alg_FrameCopy? Thanks!

Responses:
Hi Yuling Ma, Once the Can message is received, you could issue a system command to the FrameCopy link. Please note that this would should be a custom command update FrameCopyLink will have to be updated to service this command. (System_linkControl()) You could refer "GRPX_SRC_LINK_CMD_PRINT_STRING" for implementing a system command. Regards, Sujith System_linkControl

Hi， Thank you very much for your reply. I still have a question: I am using the DCAN port to receive CAN data from other boards. After receiving a few hundred frames, I will enter an infinite waiting program.

Hi Mary, Sorry, i lost this thread. Is this issue resolved? Regards, Sujith

Hi， Yes，I already solved this！ Thanks，again！
