Update
Harald_____________ early unit going his way. Massimo___________ 1 unit Thomas____________ ? Neil_______________ 1 kit hp41cx____________ 2 units Sylvian____________ 1 unit (10-11-2014 11:50 AM)Thomas Radtke Wrote: I'd participate as well, but with no ISP at hand and no intimate knowledge of the 25, others will do better. Anyway, nice to see how things develop. Hope you can still get enough LED modules when the replacement boards are ready. Fingers crossed.Do you want to pass on the 1st batch and may be order when the 2nd batch is available? Please indicate, thanks.

Or will flash an initial load for us?All kits will have pre-programed (and tested) msp430g2533 microcontroller. If you have your own tactile buttons (you need 32 of them) and other common parts. I can ship an "essentials only" kit of (pcb + mcu + 74hc164) for $12 (plus whatever shipping). $20 for a kit that does not include the bubble leds (like what Harald got). Also the price is in Canadian Dollars, although I don't mind US$ :-). If you plan to do some development or wants the ability to do firmware upgrades, the easiest path would be to get a TI Launchpad G2 (MSP-EXP430G2). It's a real bargain. When they launch it costs $4.30 incl shipping. Now they are priced at $10.00, and you got two MCUs (a 8k and a 16k msp430g2 mcus). You can get them at the usual places like digikey, mouser, newark, jameco, etc. The PCBs you will get always have a headers pad to for connecting to a Launchpad for Spy-Bi-Wire programming (it's like a two-pin Jtag). You can temporary "friction-fit" a 4 pin header for programming. You can also use these "grabbers" to attach the MCU to a Launchpad for programming. If you just need to flash firmware, you can download either one of these two tools. http://processors.wiki.ti.com/index.php/...430flasher http://mspdebug.sourceforge.net/ If you plan to do some programming or poking around, you will need the mspgcc toolchain. I develop on both windows + cygwin and linux environment, please dig around a bit how to setup. I can help on specifics when u are stucked. I did this project on mspgcc only, other compilers (CCS, IAR) usually takes more space and not likely to work. |
