STEVAL-ICB004V1 STMicroelectronics

STEVAL-ICB004V1 Advanced resistive touchscreen controller demonstration board based on the STMPE811 Data brief Features Four-wire resistive touch-sensing demonstration GUI Configurable touch-sensing parameters STMPE811 GPIO expander functionality hardware support Hardware configurable jumper headers offer freedom for easy interfacing of touchscreen controller in user designs USB universal dongle functionality for STM32 2 microcontroller SPI and I C interfaces Run-time application firmware upgrade using STEVAL-ICB004V1 DFU RoHS compliant Description The STEVAL-ICB004V1 board demonstrates the high-speed resistive touch-sensing functionality of the STMPE811 advanced resistive touchscreen controller. The board offers the added functionality of a USB universal dongle for I2C and SPI interfaces, and DFU (device firmware upgrade) protocol for run-time firmware upgrades. The STEVAL-ICB004V1 includes the STMPE811 demonstration GUI software (for Windows XP) to capture writing/drawing events on the touchscreen. The board also includes an additional UUSCI (universal USB-to-serial communication interface) GUI for evaluation of 2 different I C and SPI sensors, and a DFU GUI for run-time firmware upgrades. The many functions integrated in this single board render the STEVAL-ICB004V1 a multi-purpose demonstration platform for evaluating the STMPE811 advanced touchscreen controller.
