    Chakra, We actually have a code example that implements a software UART using the Timer_A. Please see the follwing zip file from www.MSP430.com for several different examples: http://www.ti.com/lit/zip/slac011 (namely, see msp430x11x1_ta_uart19200_01.c)

    BrandonElliott
    Hi, The UART protocol is digital already, you should be able to plug and play with a code example for USCI channel A0 in UART mode (provided your device has the USCI). It should only be noted that the input voltage levels are valid per the spec in the datasheet.

    sam22 I have another doubt is UCA0RXBUF on port 2 or port 4?? You were right to query about the port number. Got a reply from EPIC this morning and they pointed out that the Experimenter's Board (MSP430FG4618/F2013) uses P2.4 for UCA0TXD and P2.5 for UCA0RXD. I made the mods to msp430xG46x_uscia0_uart_9600...

    Sid, You should be able to use the PCMCIA card if it looks like a COM port to the laptop. Have a look in Control Panel->System->Hardware tab->Device Manager->Ports (COM & LPT), you should see one related to the PCMCIA card there. Then, use this port in the terminal application. ...

    One additional data point. When I connect to the bluetooth chip on our board with my laptop, I do get 1 character from the BT chip [out of the 14 it sends when it gets a connection]. The other characters just never seem to make it to me. Would this indicate a baud rate problem or some other problem?

    BrandonAzbell
    Is the one character you do receive an expected value? If it is not the value you expect, I might expect a baud rate issue, but the only way to be sure is to use an oscilloscope to verify what is actually being sent and compare to what is being captured by the MSP430. What does your software do when...

    Have you looked at the code examples (SLAC166) provided on the MSP430F5438 Product Folder ? There are a couple of examples that configure the USCI for UART mode and use LPM0 and LPM3. They do use a different targeted baud rate, but this should provide some guidance. I realize this isn't a definitive...

    What hardware are you using which has the MSP430F2618 on it? Would you be able to post your modifications to the MSP430x261x_uscia0_uart_01.c which have it configured to use UART A1?

  • Forum Post: Re: MSP430F2618 and NS LM9838 Bluetooth Chip

    BrandonAzbell
    At this point, I think it is prudent to verify the baud rate before looking at other items. The USCI interface is going to be driven by the same clock for both the RX and TX operations. It would be easier to verify the baud rate by using some code to transmit a series of known values that you can then...

    You mentioned seeing signals on the RX line from the PC when using either USCI A0 or USCI A1. Where are you measuring these? Is it on the CCMSP-EM430F2618 board?

    I assume you are wanting to send several bytes of information between the MSP430FG4618 on the Experimenter's board and the MSP430F2274 on the RF2500 radio target board, as well as vice versa. If so, I would suggest using one of the serial interfaces of both devices for this communication. However...
