01
Operator tasks
Prioritize status, alerts, setup and control workflows around what the operator does in the field.
Agricultural equipment HMI
Build an operator HMI for machines that work in the field.
Agricultural and off-highway equipment brings together machine status, operator workflows, display environment and connectivity. Validate those constraints before locking the platform.
Start with requirements
Clarify the HMI workload before choosing the platform.
The goal is not to force every product into one architecture. These are the decisions that narrow the practical options.
02
Display conditions
Consider size, brightness, touch method and enclosure integration for the actual environment.
03
Machine interfaces
Define controller, sensor, vehicle-bus and wireless connections before hardware freeze.
Architecture options
Choose the software and compute class from the real workload.
A focused control UI, a graphics-rich real-time interface and an application-style Linux HMI have different engineering and lifecycle trade-offs.
Compact RTOS HMI
For focused machine interfaces with fast boot, controlled UI scope and deterministic behavior.
Performance RTOS HMI
For richer monitoring, more pages and graphics while retaining an embedded real-time stack.
Embedded Linux HMI
For larger displays, complex workflows, networking or application-style functionality.
Hardware + software stack
Evaluate the complete HMI path.
01
Display & touch
Match TFT and touch choices to viewing, glove/use conditions and mechanical design.
02
Compute
Select the platform from UI complexity, interfaces and startup requirements.
03
GUI
LVGL, Qt or another stack should fit the screen flow and engineering team.
04
Connectivity
Plan CAN/serial/Ethernet and wireless interfaces as the equipment architecture requires.
05
Storage
Account for assets, logs, configuration and update images.
06
Engineering
Validate BSP, drivers, UI, interfaces and production transfer on the target system.
Reference path
Reference demo: 7-inch Agricultural Monitoring HMI
A 1024×600 touch interface for machine data and field-equipment workflows gives a concrete reference for discussing display, UI and platform trade-offs.
Before hardware freeze
Validate what can become expensive later.
01
Sunlight/readability
Evaluate the actual display under expected viewing conditions.
02
Touch behavior
Test the intended touch method with the real mechanical stack.
03
Machine data
Run realistic status and alarm updates, not static screens.
04
Startup
Measure boot and application-ready time on target hardware.
05
Connectivity
Exercise controller and wireless links through disconnect/reconnect cases.
06
Production fit
Confirm display, compute and module supply against expected lifecycle.
