Part Number: MSP430F6779
Other Parts Discussed in Thread: MSP-EXP430F5529LP

Hello,

We are using MSP430F5529LP launchpad for programming MSP430F6779 IC and the Energy Measurement Design Center software for energy measurement applications.

We followed the steps mentioned in the Energy Measurement Design Center Guide and when we try to connect, we get Error message "No HID connected Devices".

Please help us to resolve this problem.

    Hi,

    I am checking on the Energy Measurement Design Center Guide. And you error message is "No HID connected devices". So, the issue should related to the MSP430F5529LP as the HID bridge. 

    Have you downloadTI_MSP_HIDBRIDGE__1_00_04_00__MSP-EXP430F5529LP.txt to the F5529LP following the section  Program the MSP-EXP430F5529LP (HID Bridge)? 

    Best regards,

    Hello,

    Thank you for your response.

    Now we are able to connect MSP430F6779 to EMDC software via Launchpad.

    We want to communicate microcontroller and MSP430F6779 using UART. To get current, voltage and other data from MSP430F6779, microcontroller needs to send some command.

    Can you send us the command packet which we need to transmit by the microcontroller, so as to receive required data from MSP430F6779.

    Please guide us for the same.

    Hello,

    As target(MSP430F6779) gets connected to EMDC software via UART and we receive data in EMDC software. so we tap RX and TX pin and connect it to FTDI to TTL converter to get packets that EMDC send to Target and Target sends to EMDC 

    We have made command packets that EMDC transmit to target and we are transmitting the same packets by using serial terminal software but we are not able to receive data from the target(MSP430F6779).

    following are the setting:

    baud rate: 250K, data bits:8, stop bit:1, parity:none.

    We are transmitting Following command:

    0x55,0xAA, 0x07, 0x04, 0x02, 0x00, 0x00, 0x00,0x06,0x00

    0x55,0xAA, 0x06, 0x04, 0x03, 0x01, 0x01, 0x09,0x00

    0x55,0xAA, 0x07, 0x04, 0x04, 0x00, 0x00, 0x00,0x08,0x00

    0x55, 0xAA, 0x06, 0x04, 0x01, 0x01, 0x01, 0x07, 0x00

    Please Guide us if we are missing something.
