Questions about HEATEVM REV B(TIDA-00002)

Other Parts Discussed in Thread: TIDA-00002, ADS1278-HT, TMS470R1B1M, SM470R1B1M-HT, REF5025-HT

Hi,

I got a HEATEVM REV B board ( that is,TIDA-00002 ) and I need to use it for down hole drilling. I have few questions about using it.

1. As the User Guide says, we need external power. now I have a power supply board which can convert 12V to 3.3V,1.8V and 5V. Do I  just link the power line to JP2, or I should generate the power-up sequence of ADS1278-HT and SM470R1B1M by myself ?  Has "the Power HEATEVM"  been released?

2. Does HEATEVM GUI Software (Rev. A)  also work for TIDA-00002? If does, In order to run this application,what should I do on the board,which jumpers should be jumpered?

3.I want to use the IAR embeded workbench for ARM to develop it. I build the example from example project for TMS470R1B1M, and use J-Link to download the bin file, but it can not connect the target. Does anybody know how to use the IAR to develop for TIDA-00002?    Maybe I should solve the power problem first.

Regards,

Shaw

    Shaw, the HEATEVM as the name states, is an Evaluation Module. It is NOT intended, under any circumstances, to be used as a production tool or in real life applications. All this is described in pages 20-23 of the HEATEVM user's guide. Regarding your questions:

    1. The power-up sequence used for the HEATEVM must comply with the power-up sequence requirements for the ADS1278-HT and the SM470R1B1M-HT. Attached is a power sequence we use for the HEATEVM. The POWER HEATEVM has been on hold for quite a bit, if released, it might be a reference design only.

    2. The TIDA-00002 is the HEATEVM so yes, you can use the software posted in the HEATEVM product page. The HEATEVM is shipped only with one default jumper. It is in fact soldered, it's pin 1-2 in JP10 (to set the FORMAT[2:0] of the ADS1278-HT to 001 - SPI, TDM, fixed). Other than that, since there are multiple test scenarios for this board, it's really up to the user to define what to enable on the board. That being said, the RTD can be enabled closing pins 1-2 and 3-4 in JP4. Pins 1-2 in JP5 can be shunted to use the REF5025-HT as the reference for the board. JP13 can be closed to disable the clock division feature in the ADS1278-HT and all the jumpers in JP16 can be closed to connect the ADS1278-HT to the SM470R1B1M-HT. Using this configuration should allow to test quite a few scenarios.

    3. My colleague Wade Vonbergen will address this question.

    Thanks,

    With respect to question 3. The HEATEVM firmware was created in IAR workbench, so it is the preferred solution. Please post back if you still have connection issues after powering up the board.
