    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)

    Hi, Have you check with a Serial Monitor Sniffer if anything from the Firmware is transmitted over the serial port to a PC? http://www.developer.com/net/cplus/article.php/633421 http://www.lvr.com/serport.htm http://www.serial-port-monitor.com/ LPRF_Rocks

    TimHarron
    Are you using the DM642 Video Port Mini-Driver in addition to the UART driver for the DM642 EVM? There was a problem in the VPMD which overwrites a few registers in the EVM's FPGA which essentially disables the UART. This is a simple fix, so if you are in fact using the VPMD and UART drivers I will...

    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.

    The interrupt mode should work, the driver should be handling the HWI for you already based on how the example is setup. It may be worth trying out the example within C:\dvsdk_1_01_00_15\psp_1_00_02_00\pspdrivers\drivers\uart\sample to verify it works on your platform, the example utilizes the interrupt...

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.

    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?

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

    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...

  • 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...

    Dirty Harry
    Hello - It looks like there are some typos on the CC2480 pin direction. Please remember that the CC2480 is a slave device in SPI mode and a DCE in UART mode (so a pin direction is opposite the intuitive direction implied by the name.) So, it is correct to realize that the CC2480 pin directions in UART...
