How to change to 640*480?

Pixy Software
#1

Hello,

I need to change frame from 320200 to 640480. Therefore, I replace CAM_RES2_WIDTH with CAM_RES1_WIDTH, CAM_RES2_HEIGHT with CAM_RES1_HEIGHT, CAM_GRAB_M1R2 with CAM_GRAB_M1R1, SRAM1_LOC with SRAM0_LOC and SRAM1_SIZE with SRAM0_SIZE. But I get following error messages. Please help me to verify that. Thank you.

Hello Sheng,
Bear in mind that Pixy has 72K of memory for grabbing frames, which isn’t enough to grab an entire 640x400 frame.

There’s some more information here:
