Tool/software:
Hello All,
I am referring to TRM SPRUJ55A. I have a question regarding DAC conversion equation.
On pg 551 in section 7.5.5.2, the DAC formula is mentioned as shown:
But in CMPSS module, section 7.5.4.3 on pg 541, the DAC formula is mentioned as
Please let me know which is the correct equation.
Thanks,
Arjun
Hello Fleenor,
I further needed a clarification regarding this. I am following example "CMPSS Asynchronous trip" from AM263Px MCU+ SDK 09.02.00.
As shown, internal DAC is configured to VDD/2. But in sysconfig file,
DAC value is entered as 2048 for VDD/2. This doesnt hold with the equation on PG 541 is specifically for the embedded DAC within the CMPSS. But works with the equation in DAC module.
Kindly advise.
Hello Arjun,
Apologies for the confusion here. The first equation is actually applicable to both DAC's in this case. An extra factor of 33 was included in the second equation and this is incorrect. I will make sure the following equation is added to both sections for clarity.
Best Regards,
Zackary Fleenor
