STMicroelectronics STEVAL-ICB004V1

Overview

STEVAL-ICB004V1 from STMicroelectronics is an advanced resistive touchscreen controller demonstration board built around the STMPE811 IC, supporting four-wire resistive touch sensing, configurable touch parameters, GPIO expansion, USB universal dongle functionality for SPI/I²C interfaces, and run-time firmware upgrades via DFU protocol. It targets embedded human-machine interface (HMI) evaluation in industrial control panels and portable medical devices.

For engineers reviewing the STEVAL-ICB004V1 datasheet, STEVAL-ICB004V1 pinout, STEVAL-ICB004V1 application, or STEVAL-ICB004V1 equivalent, key selection considerations include its integrated STMPE811 controller, dual-interface USB dongle capability, real-time firmware upgradability, and GUI-supported touch event capture on Windows XP.

Technical Context

The board implements the STMPE811's 12-bit ADC-based touch coordinate acquisition with programmable sample averaging and debounce timing, enabling sub-millisecond response for stylus or finger input. It integrates dedicated hardware for touch screen controller initialization, calibration sequence execution, and interrupt-driven coordinate reporting.

USB-to-serial bridge functionality supports both I²C and SPI sensor evaluation through a UUSCI GUI, while DFU mode allows firmware updates without external programming hardware. The board includes jumper-configurable interface routing between STMPE811 and host microcontroller (e.g., STM32), with JTAG support for debugging.

FAQ

Is STEVAL-ICB004V1 still in active production?

No. STEVAL-ICB004V1 is marked as obsolete per STMicroelectronics' official documentation (Doc ID 17238 Rev 1, February 2011). Aetrix Electronics maintains limited legacy stock for design continuity and repair support, but no new manufacturing is planned.

What operating systems support the included GUI software?

The demonstration GUI software is explicitly validated for Windows XP only, as stated in the official data brief. No official support exists for Windows 7/10/11, macOS, or Linux; compatibility on newer OS versions requires third-party driver adaptation or virtualization.

Can STEVAL-ICB004V1 interface directly with an STM32 microcontroller?

Yes. The board provides jumper-selectable SPI and I²C signal routing between the STMPE811 and external host processors. Schematic Figures 1 and 2 confirm dedicated headers for STM32 connection, and the USB dongle mode can be disabled to use the board solely as a touch controller peripheral.

Does the board support five-wire or capacitive touchscreens?

No. STEVAL-ICB004V1 is designed exclusively for four-wire resistive touchscreens, as confirmed by its schematic, GUI functionality, and STMPE811 datasheet limitations. It lacks hardware or firmware support for five-wire resistive or any capacitive sensing topologies.
