ANALOG DEVICES EVAL-AD5592RPMDZ Pmd Ard Int Lcz User Guide

General Description
The PMD-ARD-INT-LCZ hardware user guide provides information on the Arduino interface found on many development platforms and prototype designs. The board features on-board I2C pull-up resistors for high load devices, which are jumper configurable.

Adapter Board Hardware
The adapter board hardware includes SPI Pmod connectors (P11,P12, and P16) and an I2C Pmod connector (P13) for various connectivity options with Arduino.

SPI Pmod Connectors
The SPI Pmod connectors (P11, P12, and P16) follow the expanded SPI interface. P16 can be configured as expanded SPI or expanded UART based on the shunt connector positions.

I2C Pmod Connector
The I2C Pmod connector (P13) provides I2C connectivity with pull-up resistors (4.7 k) for SCL and SDA lines. Jumper shunts are inserted by default to use these pull-up resistors.

UART/SPI Pmod Connector
The UART/SPI Pmod connector (P16) can be reconfigured between expanded SPI and expanded UART by setting the shunt connectors in different positions.

Product Usage Instructions

SPI Pmod Connectors Configuration

To configure P16 as expanded SPI, set the shunt connectors (P8,P9, and P10) in position A as per Table 1.

Refer to Table 1 for the pinout details of SPI Pmod connectors (P11, P12, and P16).

I2C Pmod Connector Configuration

By default, jumper shunts are inserted on P11 and P12 to use the pull-up resistors for the I2C Pmod connector (P13).

Refer to Table 2 for the pinout details of the I2C Pmod connector (P13).

UART/SPI Pmod Connector Configuration

To configure P16 as expanded UART, set the shunt connectors (P8, P9, and P10) in position B as described in Table 3.

Refer to Table 3 for the pinout details of the UART/SPI Pmod connector (P16).

GENERAL DESCRIPTION

The Arduino interface is found on many development platforms and is used in many prototype designs. The PmodTM standard is a 6- , 8- , or 12-pin standard that carries GPIO and/or serial commu-nication protocols. The PMD-ARD-INT-LCZ, a low-cost interposer, enables four Pmod modules to interface with the EVAL-AD5592R-PMDZ, EVAL-AD5593R-PMDZ, or EVAL-AD5770R-PMDZ evalua-tion boards or any equivalent Arduino MCU boards. Additionally, there is a connection matrix that allows external signals from any microcontroller to connect to the four Pmod ports. Out of the four Pmod ports, two ports are configured as SPI Pmod, one is configured as I2C Pmod, and the remaining port can be configured as either SPI or UART Pmod.

Figure 2 shows the allocation of the four Pmod connectors and the connection matrix in the central part of the board, for more detailed information about the matrix connection see the Changing the Arduino GPIO Assignments section.

SPI PMOD CONNECTORS (P11, P12, AND P16)
The Pmod ports (P14, P15, and P16) follow the expanded SPI interface. P15 and P14 are dedicated SPI ports while P16 can be configured to either expanded SPI or expanded UART. Table 1 provides the signal pin assignment for connectors P11, P12, and P16.

To configure P16 as expanded SPI, set the shunt connectors, P8, P9, and P10, in position A as shown in Table 4.

Table 1. SPI Pmod Connectors P11, P12, and P16 Pinout

I2C PMOD CONNECTOR (P13)
Pmod devices that use the I2C interface should be connected to the 2 × 6 female header, P13. Table 2 lists the default Arduino Uno signals pin assignments for the P13 connector.

Table 2. I2C Pmod Connector P13 Pinout

Pull-up resistors (4.7 kΩ) for the SCL and SDA lines are also provided. By default, jumper shunts are inserted on P11 and P12 to use the pull-up resistors.

UART/SPI PMOD CONNECTOR (P16)
The Pmod port (P16) can be reconfigured between an expanded SPI and expanded UART. To configure P16 as expanded UART, set the shunt connectors P8, P9, and P10 in position B.

Table 3. SPI/UART Pmod Connector P16 Pinout

Table 4 shows the positions of shunts P8, P9, and P10 in order to select between expanded SPI or expanded UART.

PMOD VCC VOLTAGE SELECTION
Following the Pmod standard, Pin 6 and Pin 12 of the 4 Pmod connectors are assigned by default to the 3.3 V supply from the Arduino P2 connector. The PMD-ARD-INT-LCZ provides a series of resistor jumpers to select whether 3.3 V (by default) or 5 V from the Arduino P2 connector is used. Table 5 shows the resistor jumper name, the position, the applied voltage on the jumper, and the Pmod to which the signal is routed.

SUMMARY OF SIGNAL MAPPING BETWEEN ARDUINO AND PMOD
Table 6 provides an overview of all signals originating from the Arduino shield to the Pmod connectors P13, P14, P15, and P16.

CHANGING THE ARDUINO GPIO ASSIGNMENTS

The PMD-ARD-INT-LCZ maps all the signal pins of the Arduino Uno to the pin matrix, P6 and P7. The adapter board is designed so that all of these input/output (I/O) signals pass through the rows of test points and solder jumpers at the center. This way, if a different set of GPIO pin assignments is needed (or desired), the default connections can be changed simply by removing the appropriate solder jumper(s) and then placing a wire between the desired test points. Refer to Figure 4 and Table 7 below for the signal names available on each test point.

Arduino Uno GPIO signals are connected to P6 while P7 connects to the Pmod peripheral connectors P13, P14, P15, and P16.
