Writing in a GENX320 register

Writing in a GENX320 register

Hi !

I'm trying to measure the quantum efficiency for GENX320. I'm trying to follow the same procedure as in the related article https://support.prophesee.ai/portal/en/kb/articles/qe-estimation
As the article mentions, quantum efficiency can be determined by :

I need to access the value of Iph.
As the GENX320's datasheet mentions,  the illuminance sensor outputs a digital count value.
To acquire this digital count value,  the first step is to set a register's bit value to 1:


There is an example on the sdk on how to write register values (https://docs.prophesee.ai/stable/faq.html:) 

From this, I tried writing in the register with the Python SDK :


This outputs [HAL] [ERROR] Write : Invalid register.
I tried to do the same function on other registers but i get the same output.

The same test isn't fruitful with the SDK driver C++ API :  I created a hw_register pointer and its memory allocation doesn't seem to work :



I get this message when running the debugger:

This does the same when I use the HALL C++ API. 

Do you have any suggestions on how i could make this work ? Am I missing anything ?

Cheers,

Michael
