• The receiving SPAD array includes 16x16 SPADs which covers full
FoV. It allows to narrow down FoV by programming smaller ROI.
Minimum ROI size is 4x4.
• In order to set ROI, top left and bottom right coordinates are required.
• Receiver field of View can be narrow down from 27° to 15 °.
Example to set one ROI:
VL53L1_UserRoi_t roiConfig;
roiConfig.TopLeftX = 9;
roiConfig.TopLeftY = 13;
roiConfig.BotRightX = 14;
roiConfig.BotRightY = 10;
status = VL53L1_SetUserROI(&VL53L1Dev,
roiConfig);
