Tool/software:
I want to use the DLPC3479's "Read System Temperature (D6h)" command to get the temperature of the thermistor connected to ACMPR_IN_2 of DLPA3005.
AFE_SEL is the default ILLUM_A_FB/xx, so I need to change AFE_SEL.
How can I change the AFE_SEL register?
Hello Koichi-san,
Thank you again for reaching out to us through E2E!
Are you utilizing the DLPC4710EVM-LC or is this a custom system?
If you have the GUI and can communicate with your system, you may utilize the 'Advanced' section of the GUI and go to 'Commands' -> 'System' -> 'Read System Temperature' and perform a Get.
If you have followed our connections, as you've stated utilizing ACMPR_IN_2 of DLPA3005, you can transmit D6h command, you will receive the parameter in a 2-byte return. Please read 3.6.7.2 Return Parameters closely to understand the sign of temperature and magnitude of temperature accordingly.
Below I did this 3 times - I don't have a temperature sensor connected at returned nothing.
Best,
Aaron
Dear Aaron-san,
Thank you for the reply.
I am using a custom system and the temperature sensor is connected to ACMPR_IN_2 of DLPA3005.
As shown in the attached image, I think I need to set the AFE_SEL register to read ACMPR_IN_2.
Could you please tell me how to set the AFE_SEL register?
Best Regards,
Kadowaki
