as7421 problem with SMUX and GAIN configuration

TU1234 — Fri, 30 Aug 2024 10:11:38 GMT

Hello,

I'm trying to configure the SMUX and ADC gain of the as7421, but the files explaining the configuration specified in the datasheet are missing and the company's support does not respond to my messages. I have already readout the specified RAM, but have not yet been able to recognize a pattern in the data that has already been entered in order to know where I have to write which values into the RAM. Has anyone solved a similar problem? I would appreciate it.

I am trying to control the as7421 to read spectral data using python's smbus, but there is a problem that I can't change the value of LTF_EN on the enable bit 0x60, so I can't take spectral measurements, has anyone solved a similar problem, I'd appreciate it!
