Can anyone point me to an MSP430 development board ready to accept a mass storage card (SD, Memory Stick, etc) that I can program to use for a data logger.

I can take care of getting the data into the processor and formatting it; so far have not be able to find a way to store the 6 Mb of data that will be collected.

Thanks!

I can't suggest a particular board, but if you're burning your own, SLAA281 (http://focus.ti.com/lit/an/slaa281b/slaa281b.pdf) will show you how. Hope this helps at all.

I don't know of any off hand, which is a gap that needs filling.

If you are going to roll your own, and are running on batteries for long periods of time (why else use an MSP430? ), make sure to firmly turn off the SD card via a FET or similar - some have significant idle currents.

^^^ Very good point. Also make sure to HIZ any UART lines when powering off.

I found a MSP430 development board with an SD card slot: the Olimex MSP430-169LCD.

Unfortunately this board does not have an implemented comm port (which I need), although the 169 has a USART interface. Anyone know of a simple TTL-to-RS232 interface I can attach?

Mateja and Theatrus, I appreciate your comments; will watch out for SD card power consumption.

If you just want to hook it up to your computer, why not try one of these?

If you really do need RS-232 levels, then try this.

Thanks GM, these are just what I need!
