Q: I can't get the backchannel UART to connect. What's wrong?

A: Check the following:

• Do the baud rate in the host terminal application and the eUSCI settings match?

• Are the appropriate jumpers in place on the isolation jumper block?

• Probe on RXD and send data from the host. If you don't see data, it might be a problem on the host

side.

• Probe on TXD while sending data from the MSP. If you don't see data, it might be a configuration

problem with the eUSCI module.

• Consider the use of the hardware flow control lines (especially for higher baud rates).

Q: Is this the same LCD as the MSP430FR4133 LaunchPad?

A: Yes, this is the exact same LCD. However, there are two differences: the physical pin connections to

the LCD and the LCD module in the MSP devices themselves. The MSP430FR4133 device has the

LCD_E module, while the MSP430FR6989 has the LCD_C module. See the application note Designing

with MSP430 MCUs and Segment LCDs for more information on the differences between the LCD

modules.

Q: Can I purchase the ESI plug-in boards separately from TI?

A: These plug-in boards only come with the EVM430-FR6989 EVM, however, all design files are made

available for you to create your own. See the associated TI Design TIDM-LC-WATERMTR for hardware

design resources and Gerber files.

Q: The MSP G2 LaunchPad had a socket, allowing me change the target device. Why doesn't this

LaunchPad use one?

A: This LaunchPad provides more functionality, and this means using a device with more pins. Sockets for

devices with this many pins are too expensive for the LaunchPad target price.
