MSP430 data logger?

Development Boards MicroMod
1

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.](SparkFun RS232 Shifter SMD (No DB9) - PRT-08780 - SparkFun Electronics)](SparkFun USB to Serial Breakout - FT232RL - BOB-12731 - SparkFun Electronics)

Thanks GM, these are just what I need!
