Warning: The IR detector (PNA4602) has been discontinued by its
manufacturer. We are not going to include the IR
transceiver on the newly manufactured Dragon12P-USB
boards.
The HCS12/9S12 based Dragon12-Plus-USB board
includes a built-in USB interface based on the flawless FT232RL and an RGB
piranha color LED. It is fully backward compatible to our Dragon12-Plus
board. It will run all programs written from the Dragon12-Plus board
without any modifications.
The
kit includes the Dragon12 Plus-USB board based on
the MC9S12DG256CVPE, a solderless breadboard and a USB cable.
The SCI1 interface is changed from RS232 level to TTL level. For RS232
interface applications an RS232 to TTL adapter (RTA, $9) is required.
For customers in US and Canada, you will also receive a
free
switching power AC adapter.
SD memory card holder, SD memory & VGA camera interface circuits are
not included
in
the kit.
The SD memory and
VGA camera interfaces can only be installed at factory.
Before purchasing the SDVGA option ($20) please read the
SD
memory interface
page.
The 2-position mode-switch (SW7) located next to the ground test
point is used for selecting one of 4 operating modes and
the LCD display module will show the selected
operating mode when the board is turned on or reset. When you learn
HCS12/MC9S12 programming with D-Bug12 monitor, you will
have to change operating modes of the HCS12/MC9S12 quite often, so this is a useful
feature.
