Hi,

we have used Energy measurement design center to generate code and flashed it successfully in the MSP430I2040 chip. There is already UART port is available in the board but after programming it doesn't send any data to GUI. Does MSP-EXP430F5529LP is needed for generating source code in design centre?

Link - In this link I have found that launchpad is used in between PC and MSP430 device.

Hello,

Yes, the MSP-EXP430F5529LP is required for communication to the PC GUI. This board acts as a HID bridge. The link below shows the details of how these are connected(Make Hardware Connections section). The isolation board is also recommended for protection.

Eddie,
Thanks. Can't I connect uart pins of msp430i2040 to an isolator and then to serial com port of pc GUI through a usb-serial converter?.
In user guide of TIDM-TWOPHASEMETER-I2040 it is mentioned to connect rs232 to pc GUI. Similarly we have already used msp430f6779 in TIDA-0222 in which we directly connected to pc com port .

In this case, the Design Center software is interfacing with a HID USB device(MSP-EXP430F5529LP). A USB serial port is not what the Design Center GUI is designed to interface with.
