is a kit by TI available with more than 30 GPIO pins and atleast 2 UART ports?

Other Parts Discussed in Thread: MSP430F6659, MAX3238

I have found out about  MSP430F6659. It has 74 GPIOs and 2 USCI channels [channel A (3 - UART / IrDA / SPI) and channel B (3 - SPI / I2C)] . But there is no kit which has this MCU.

Please tell if there is a kit available with more than 30 GPIO pins and atleast 2 UART ports. Kit other than MSP430 will do but should be programmable using C language ( like the CCompsoer Studio etc. ).

Please reply, it's urgent.

thank you.

    Vasu:

    The MSP-FET430U100USB supports the F6659, but it is a "bare-bones" board. It brings out all of the I/Os to pins, so it would definitely give you the 30+ GPIO pins necessary. You would need to add support for the UARTs - there are no chips on the board for UART support. You would need to add an external MAX3238 or similar part to be able to interface to 5v.

    By the way, there is a small board available from Sparkfun Electronics that will allow a DB9 connection and do the translation from PC (5 volts) to MSP 3 volts. You may want to check out the "RS232 Shifter SMD" board on their website.

    I just looked at the I/O pins on the Launchpad F5529, and counted 35 I/O's available. If 4 of these are tied up with UART connections, then it looks like you still have 31 available. Again, there are no UART drivers on this board, but if you procurred those from Sparkfun and the Launchpad from TI, you would have a pretty inexpensive platform on which to build your solution.

    Hopefully, that helps.

    Thank you very much for the information.

    I just looked at F5529 launchpad's description is says it has Up to 2 I2C, 4 SPI, 2 UART. 

    I need to connect GPS and GSM with this kit and 2 UART is all that is required. Remaining I/O pins are sufficient for me to work upon.

    But as you say it doesn't have any UART drivers then how will it be possible to connect GPS and GSM ?

    How can i externally interface UART drivers with the launchpad ?

    Also please tell if MSP-EXP430G2553 launchpad has inbuilt UART driver because i can work with GPS and GSM seperately.

    I know it has only 1 UART port & 8 - I/O pins but it would do for the time being.

    Thank you.

    Regardless of the kit, you will need drivers. The Sparkfun kit that I pointed you to is an inexpensive solution that can be added on quite easily to any of these boards; it requires only 3.3 volt power, ground, RX, TX lines. It then provides a DB9 connector that will allow connection to a PC UART. Voltage translation from 3.3 to 5 volts is done by the Sparkfun card. I have used it in the past, and it works very well. I did a bit of exploration, and both of the F5529 UART's come out to pins on the Launchpad. Looks like a very good platform for what you are trying to do. There is also good training available on this particular board from TI.
