Other Parts Discussed in Thread: TDC1000, TDC7200
Hello,
I am developing a gas flow meter using TI reference design:
http://www.ti.com/tool/TIDM-ULTRASONIC-FLOW-TDC.
I have two questions:
- TX Frequency setting:
Only setting I have found on this board is TX Frequency Divider of 8MHz Clock in CONFIG0 register. I use a 218kHz narrow band transducer which requires fine frequency tuning. The EVM module http://www.ti.com/tool/tdc1000-tdc7200evm has an option to use MSP430 timer PWM output as TDC clock. Is similar option available on TIDM-ULTRASONIC-FLOW-TDC reference design? - I use TDC_1000_7200_EVM GUI 1.2.7.1 and MSP FET Tool for communication with TI reference design board. The communication works properly in SETUP, TDC1000 and TDC7200 Tabs, but does not work in TOF_ONE_SHOT and GRAPH Tabs. The GUI gives a warning after connection: “Firmware Revision 1.27 detected. GUI needs Revision 2.01 or later.” I tried to update firmware in DEBUG Tab, but I did not succeed. I guess the update is possible only with EVM.
Could you please advise how can I read TDC7200 Measurement Result Registers in TOF_ONE_SHOT and GRAPH Tabs?
Thank you,
Pavel
