Port out SPI data to UART1 of TDC1000/7200 EVM

Jomer Deogracias

Other Parts Discussed in Thread: TDC7200, MSP430F5528, MSP430F5529, TDC1000

Hello,

I want to get the data sent by the TDC7200 to the MSP430F5528 of the eval board and access it via the UART1.
In the board, there is a connector J6 which is not placed and in there are pins for the UART1TX & RX.
I'm trying to get data from these pins. How can I achieve this? How can I enable UCA1TX & UCA1RX?

I have a working version that will send out the TDC7200 calculation data through the UCSI-A1 pins. It will be released to web sometime soon. Meanwhile, I can share a pre-release. Please send me an email: vishy.natarajan@ti.com.

Jomer,

Default baud rate is set as 230400. You can set it to other rates as well. For example, to get 115200, you need to do minor modifications to files "uart_commn.c" (uncomment line 65/comment line 66) and "uart_commn.h" files (uncomment line 38/comment line 39).

You can observe the data sent out by using a UART to USB cable (like FTDI TTL-232R-3V3). Connect GND, RXD to GPIO3, and TXD to GPIO4 of the board. You can use a terminal like Teraterm to observe the data. I have enclosed screen captures of data being sent out. TOFs results are sent out as shown. Most of the applications would use 1 stop, so start to stop1 data alone is valid.

Regards,

Vishy

Hi Vishy,

Got the set-up working. Initially had problems because of physical connections between UARTs.

Attached is the screenshot of the output.

Thanks again for the help.

Hi Vishy,
I have the same problem as Norman with the TDC1110_TDC7200 EVM_Board. I can only be a baud rate to 115200 process. Where can I find the uart_commn.h for the Board?
I have a second problem pad and the TDC7200 with the combination of MSP430F5529 lanch pad. There I would like to read even the UART.
GreetingsFrank

My firmware for the MSP430F5528 brings no signals on GPIO3 and GPIO4. Can you send me the firmware as for Jomer?

Hello Frank,

An updated version of the TDC1000_7200EVM GUI is going to be available on the web in the next few days. This version v1.0.9.0 includes the UART data out support explained in this thread. If you need it immediately send me an email vishy.natarajan@ti.com.

We have not tested this support with MSP430F5529 launch pad yet. The backchannel UART of launchpad corresponds to USCI_A1 module which is what we have used in the TDC1000_7200EVM.

Regards,

Vishy

Hello, can you specify, where exactly on J6 should I connect GND? To which pin?

Hi,

J6 pin 9 is ground. You can find the schematic of the EVM in the User's Guide (link below)
