■
28-pin socket – Analog parts. This is connected differently and is described
separately below.
■
40-pin socket – A/D Parts. Port A is connected to header marked “Analog”, not the
header labeled “Port A”. Port B, Port C and Port D are the same as the 40-pin digital
socket.
■
40-pin socket – Digital Parts. This is connected to headers marked “Port A”, “Port B”,
“Port C” and “Port D”.
■
20-pin socket. Port B and Port D are connected to headers marked “Port B” and “Port
D”.
■
8-pin socket – This is connected to Port B with a slightly different layout and is
described separately below.
In addition to the port pins, each header has a connection for ground and V
CC
to supply
external circuits. This voltage V
CC
will be either 3.3V or 5V depending on the setting of
jumper 1 JP1 and the brown-out detector will operate as normal (see “Brown-Out Detec-
tor” on page 8-1).
Note:
If your circuit is to draw significant current >250 mA then a heat sink will be
required on the on-board regulator—LM317. This device is rated at 1.5 Amps
but it needs a heat sink to supply this current. If your circuit will draw more than
1 Amp, you may need a separate power supply.
9.3.1
20-Pin and 40-Pin
Digital Sockets
The ports on the 40-pin digital socket are connected to the headers marked “Port A”,
“Port B”, “Port C” and “Port D”. The 20-pin socket is connected to the headers marked
“Port B” and “Port D”. The layout of all the headers is the same and is shown in the fol-
lowing diagram.
9.3.2
40-Pin A/D Socket
The layout, shown above, applies to Port B, Port C and Port D on these parts. Port A is
the Analog input port on these devices and is connected to the header marked “Analog”
NOT Port A. The layout of this header and how to use the A/D functions is described in
the section “Using Analog Parts” on page 9-3.
9.3.3
28-Pin Socket
This socket is also for A/D parts. There are three ports on this device—Port B, Port C
and Port D.
Port C is the Analog input port and it is connected to the header marked “Analog” NOT
Port C. See the section on “Using Analog Parts” on page 9-3 for details.
Port D is connected as normal—see diagram above.
