摘要
一种以STM32为核心的嵌入式语音播报系统,其核心处理器选用ST公司的基于ARM Cortex-M3内核的32位处理器STM32F103C8T6。系统的处理器接收上位机指令,解析得到文本信息,通过科大讯飞的中文语音合成板卡XF-S4240将文本信息转换为语音信息,采用嵌入式操作系统μC/OS-II来实现统一的任务调度和外围设备管理。
Design of an embedded speech brodcast system based on microprocessor STM32 series was introduced.The speech broadcast system takes STM32F103C8T6 as a core chip which is a 32-bit microprocessor built on ARM Cortex-M3 produced by STMicroelectronics Co.Ltd.The microprocessor of the system receives instructions from the host computer and gets text messages.A text to speech voice synthesizer module called XF-S4240 converts text messages to speech voice.The real-time operating system—μC/OS-II is used in the system for multitask scheduling and operation of the peripheral devices.
