Before you order...
All of our standard connector options are available for this board. The product photo above shows "F1" connector on both H1 and H2. Please make your choice of connectors before adding this item to your shopping cart. Otherwise, the board will be shipped with the default option (no connectors on H1 and H2).

Product Details

Adapt912 is functionally identical to the Freescale EVB912B32 Evaluation Board-- with a few improvements. It is in a compact, modular "Adapt12" form factor, compatible with prototyping cards, backplanes, and solderless breadboards ("proto boards"). It includes a 5-volt regulator, and both RS485 and RS232 transceivers (jumper-selectable) on board. Like the EVB912B32, Adapt912 has Freescale's D-Bug12 monitor/debugger contained in on-chip Flash. This program has four jumper-selectable modes of operation, invoked when the processor comes out of reset. Modes 1, 3, and 4 require a dumb terminal, or the use of a terminal program on a host computer (PC, Mac, Amiga, workstation, etc.).

 

Here are a few ways you can use Adapt912:

 

(1) As a standalone target, you can utilize D-Bug12 to write/debug programs in the 768-byte on-chip EEPROM. Once you are comfortable working with the chip, you can write larger applications and program them into Flash (erasing D-Bug12 first). There is a small write-protected "bootblock" in Flash, which contains the BOOTLOADER code implemented by Mode4, above, so if you wish to re-load D-Bug12 at some later time, it is quite easy to do so. By the way, the Flash is erasable/programmable thousands of times under normal operating temperatures and voltages, so you don't have to worry about wearing it out anytime soon. The necessary Flash programming voltage (Vfp) is generated on-board, and a convenient switch is provided to apply Vfp when required.

 

Any DC supply between 7 and 15 V can be used. The module draws a nominal 50 mA, so a commonly-available 9VDC adapter with a 200mA or higher rating will work fine. For portable applications, a 7.2V or 8.4V NiCd pack will be adequate.

 

(2) As a Background Debug Mode (BDM) Pod, Adapt912 functions as an interface between a terminal and any 'HC12 board (target). Just connect the Adapt912 "BDM OUT" connector to the target board's "BDM IN" connector via a ribbon cable (supplied with Starter Package). The target board could be another Adapt912, an Adapt812, Adapt812DX, Adapt912D60, Adapt912DG128, or any other 'HC12 board that has a 6- or 10-pin BDM interface connector. The host for using the BDM Pod can be any type of dumb terminal, or any computer running a terminal program. The BDM pod will receive its 5V operating power from the target board.

 

(3) As an Expanded Mode combo, utilizing the Adapt912MX1 RAM+ memory expansion card. This configuration gives you a lot more memory to work with, and a lot more code development flexibility. See the Adapt912MX1 page, and Application Note for details.
