As we are studying OPT3101 TOF technology, we find that in the file 《OPT3101 ToF-Based Long-Range Proximity and Distance Sensor AFE》 Page 105, as we calculate the illumination current should be 100mA, then
1. why set the ILLUM_DAC_L_TX0 = 2 and ILLUM_DAC_H_TX0 = 20 (which means I(illum_dac_h_tx0)=112mA, I(illum_dac_l_tx0)= 11.2mA) ?
2. Why not choose I(illum_dac_h_tx0) as 100.8mA or 106.4mA or other bigger than 100mA?
3. How to calculate I(illum_dac_l_tx0)? Is there any formula ?
4. Why set HDR_THR_HIGH as 27000 ? If we choose Super_HDR mode, how to configure HDR_THR_HIGH ?
