OK, suppose I were to spend $20 on the TI ez430 gadget...
How easy would it be for me to build a programmer for the 14-pin DIP MSP430 chips? Would it be a simple matter to replicate the "target board," larger, with a DIP socket?
Yes, I think so. We are trying to do the same. The boards have 4 pins connector.
2 for power and 2 for modified Jtag. I'll buy some if you do the layout."mc" schrieb im Newsbeitrag news:jOleg.87159$ snipped-for-privacy@bignews5.bellsouth.net...
MSP430
larger,
It's easy, if you have a 4 pin 0,05" plug for the ez430 programmer.
Build yourself your 14pin DIP target board as on page12 here:

You want DIP or SMT?

I'm not that deep into the project, but it's an "inquiring minds want to know" kind of thing...
Thanks! That looks extremely simple provided I can find the appropriate plug. (I don't have an eZ430 right now so I don't know what it looks like.) How hard is the plug to find?
Note that your replacement target board won't work with the older JTAG-only MSP's, only the new ones with the 2-wire i/f. Although DIP is easy, the SOICs aren't much harder - not hard to solder or to find a suitable proto-board for.
If you do a board, leave a spot for a 32KHz xtal so you can calibrate the internal clock for apps that need a fixed clock.
