Detailed Description
I
2
C Interface
The MAX44000PMB1 peripheral module can interface
to the host in one of two ways. It can plug directly into a
Pmod-compatible port (configured for I
2
C) through con-
nector J1, or in this case, other I
2
C boards can attach to
the same I
2
C bus through connector J2.
I
2
C Interface (Daisy-Chaining Modules)
Alternatively, the peripheral module can connect to other
I
2
C-based Pmod modules using a 4-conductor ribbon
cable connecting to the J2 connector. In this situation,
pins 1-4 and 5-8 on J2 provide two connections to the
I
2
C bus, allowing the module to be inserted into an I
2
C
bus daisy-chain.
Connector J1 provides connection of the module to the
Pmod host. The pin assignments and functions adhere
to the Pmod standard recommended by Digilent. See
Table 1.
The J2 connector allows the module to be connected
through a daisy-chain from another I
2
C module and/or
provide I
2
C and power connections to other I
2
C modules
on the same bus. See Table 2.
