TI TIDEP－0087电动汽车(EV)充电桩人机接口(HMI)参考设计

TI公司的TIDEP-0087是采用AM335x系列微处理器的电动汽车( EV)充电基础设施人机接口(HMI)参考设计,采用软件加速图像和Qt电阻触摸屏,4.3吋LCD支持480x272分辨率,其它显示器可升级2048x2048,主要用在电动汽车(EV)充电桩HMI模块.本文介绍AM335x系列微处理器主要特性和功能框图,参考设计TIDEP-0087主要特性和框图,以及TMDSSK3358评估板电路图和材料清单.
The AM335x microprocessors, based on the ARM Cortex-A8 processor, are enhanced with image,graphics processing, peripherals and industrial interface options such as EtherCAT and PROFIBUS. Thedevices support high-level operating systems (HLOS). Linux® and Android™ are available free of chargefrom TI.
The AM335x microprocessor contain the subsystems shown in Figure 1 and a brief description of eachfollows:
The microprocessor unit (MPU) subsystem is based on the ARM Cortex-A8 processor and the PowerVRSGX™ Graphics Accelerator subsystem provides 3D graphics acceleration to support display and gamingeffects.
The PRU-ICSS is separate from the ARM core, allowing independent operation and clocking for greaterefficiency and flexibility. The PRU-ICSS enables additional peripheral interfaces and real-time protocolssuch as EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, Ethernet Powerlink, Sercos, and others.
Additionally, the programmable nature of the PRU-ICSS, along with its access to pins, events and allsystem-on-chip (SoC) resources, provides flexibility in implementing fast, real-time responses, specializeddata handling operations, custom peripheral interfaces, and in offloading tasks from the other processorcores of SoC.
