Part Number: PGA900EVM
My customer is having troubles posting on the forum, so i am asking the question for them:
I have identified the following registers for configuring the evaluation board to read the internal temperature sensor, but I am not getting ALPWR = 00AMUX_ACT = 01AMUX_CTRL = 04AFE_CONFIG = 00P_GAIN_SELECT = 00PADC_CONFIG = 00TEMP_CTRL = 43T_GAIN_SELECT = 02TADC_CONFIG = 01What am I missingI am able to get a good reading through the "P" channel when I configure and connect an externally powered restive bridge. The"T" channel I am having problems with, I am not able to get any good data from it regardless of what multiplex input I use. Above is theexample of the internal temperature sensor.Also We tried loading some code in the RAM and executing from there but we were unsuccessful.What are we missing?The literature I have found is silent in discussing the configuration of registers for specific applications.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Viktor Tasevski:
We tried the setup of the registers that you recommended but still no change. the DATA registers associated with the TADC still read zero.
Are there any other registers we should be setting in addition to the ones above.

Please clarify at what point is the Remap register to be set to a value of 0x01? I indicated in my post that I have followed the procedure defined by two other TI representatives but we still do not have our source code running on our PGA900 in DEVRAM. We also performed a OTP of the same hex file. The PGA900 GUI is able to verify the programmed hex file in OTP but it does not run either when the board is powered up.
We noticed that J11 and J13 were open on the PGA900EVM board. Putting the jumpers on these pins did not make any difference. Are there any other jumpers that are perhaps keeping the microcontroller in reset?
