mcbsp配置为uart,接收采用DSP/bios硬中断,发送放在任务线程,数据可以正确接收和发送。 问题1:未使能接收中断线程,只在 DSP uart 任务线程发送数据时,经常出现中断现象,中断后,数据不能继续发送。经调试,是如下代码出现问题: old = HWI_disable(); timeout = 0; // Wait for XRDY signal before writing data ...

UART、 universal asynchronous receiver transmitter (UART) protocol is commonly used to send low-speed data between devices. Ethernet/IEEE 802.3、 ATM、 PCI、 I2C、 SPI(motorola:Serial Peripheral Interface) exchange data betweencpu andperipheral devices(such as EEPROMs, real-time clocks, A/D)convert...
