US082-ZMOD4410EVZ Evaluation Board Manual

Introduction

The US082-ZMOD4410EVZ board facilitates rapid prototyping of the ZMOD4410 gas sensor module for indoor air quality (IAQ) applications within custom system designs. It features a standard Pmod™ Type 6A (Extended I2C) connection, allowing the on-board sensor to interface with any compatible MCU evaluation kit. The board includes Pmod connectors on both sides, enabling daisy-chaining with additional Type 6/6A sensor boards. Renesas' e2 studio IDE provides software support with code generation capabilities, significantly reducing development time for sensor and MCU integration. This combination of standard connectors and software support makes the US082-ZMOD4410EVZ an ideal choice for quickly developing IoT systems using the Renesas Quick-Connect IoT ecosystem.

Functional Description

The US082-ZMOD4410EVZ serves as a sensor building block for creating custom system solutions. It can be utilized independently or in conjunction with other sensors via the Pmod Type 6A interface. For a list of available sensor Pmod boards, refer to Renesas Quick-Connect IoT. The board simplifies hardware connection and integrates with the Renesas software package, which includes a software sensor block that generates necessary glue code between the sensor and the MCU with a single click.

Setup

Required or Recommended User Equipment

The following additional lab equipment, sold separately, is required for using the board:

• Any MCU board that supports the Pmod Type 6A interface.
• The US082-INTERPEVZ interposer board if using one of the Renesas MCU kits listed in Table 1.

[1] This table is not a comprehensive list of supported MCU Kits. Refer to the evaluation kit hardware manual to confirm Pmod pinout.

Software Installation and Usage

For the latest version of the e2 studio installer, consult the Renesas website. The minimum FSP (Firmware Support Package) version required for sensor blocks is FSP 3.1.0. Ensure you are using the latest release for optimal sensor support. For more information on creating customized system solutions, visit Renesas Quick-Connect IoT.

Kit Hardware Connections

Follow these procedures to set up the kit as shown in Figure 3:

1. Ensure the MCU evaluation kit has a Pmod connector configured for Type 6A (consult the kit hardware manual if unsure).
   • If a Type 6A Pmod connector is not available, ensure the MCU evaluation kit supports the US082-INTERPEVZ interposer board. Insert the interposer board into the MCU connector before connecting any sensor boards.
2. Connect the US082-ZMOD4410EVZ to the Type 6A connector, carefully aligning Pin 1 on both the sensor board and the MCU kit.
3. Connect the J4 and J5 jumpers to enable the 4.7k pull-up resistors on the I2C bus lines.
   • Only one set of I2C pull-up resistors should be active on the bus. If multiple sensor boards are used, ensure jumpers are present on only one board.
   • MCU kits typically do not include pull-up resistors on the bus lines, but verification is recommended.
4. The INT pin of the ZMOD4410 functions as a push-pull output, signaling when a measurement is in progress.
   • To connect it to the Busy (GPIO) pin of the Pmod connector, place Jumper J6 on Pins 1-2.
   • To connect it to the INT pin of the Pmod connector, place Jumper J6 on Pins 2-3.
   • Connect Jumper J3 to add an optional 4.7k pull-up resistor to this line.

The sensor is now ready for system integration. Follow the MCU kit instructions for connecting and powering up the evaluation kit.

Programming Interface

System programming is accomplished using Renesas IDE, e2 studio. Refer to the MCU evaluation kit documentation for initial project setup in e2 studio. Adding the ZMOD4410 sensor to the project involves a few straightforward steps.

1. Navigate to the Components tab, expand the Middleware/all folder, and select the desired sensor and operating mode. For the configuration shown in Figure 4, select rm_ZMOD4xxx_rx and rm_zmod4410_iaq_2nd.

2. Click the "Generate Project Content" icon. The system will then generate the code required to configure the sensor with the MCU.
3. Implement three to four lines of code to verify the sensor version, initialize the sensor, start the measurement cycle, and retrieve data. The following is an example code snippet for an RA MCU:

   err = p_zmod4xxx_api->open(p_zmod4xxx_ctrl, p_zmod4xxx_cfg); // Configure the sensor
   err = p_zmod4xxx_api->measurementStart(p_zmod4xxx_ctrl); // Start measuring
   err = p_zmod4xxx_api->read(p_zmod4xxx_ctrl, &gs_zmod4410_raw_data, NULL); // Get data

4. Utilize the retrieved data within your application. Sample projects are available on the Renesas website.
