touchscreen ref designAvnet Electronics Marketing released a new touchscreen Human Machine Interface (HMI) reference design from Xylon for its MicroZed evaluation kit. The MicroZed is based on the Xilinx Zynq-7000 All Programmable SoC. The reference design is available for free and showcases the MicroZed working as a Linux-based System-on-Module (SOM) with a graphics touchscreen HMI that is connected to an I/O Carrier Card and the 7-inch Zed Touch Display Kit from Avnet Electronics Marketing. The MicroZed uses ilixi user interface toolkit to run several DirectFB and Qt graphics applications on the attached LCD display and to control them by the capacitive touchscreen. System designers can use the demonstrated HMI as a basis for their next Xilinx Zynq-7000-based design and integrate it with their application specific parts. The LCD display is controlled by Xylon’s logiCVC-ML advanced display controller logicBRICKS IP core, which is compatible with the Xilinx Vivado® IP Integrator (IPI) design and verification environment. The logiCVC-ML IP core supports multiple graphics layers, hardware accelerated layers blending, different pixel formats and video output formats, and comes with software drivers that assure a smooth integration with the Linux operating system.
