串口DMA下 HalUARTWrite 问题咨询

Other Parts Discussed in Thread: CC2540

亲们,

大家有没有遇到这样的情况,我用的TI 的CC2540,用DMA发的数据包,连续这样写两包同样的数据,第二包的第一个byte会丢掉,好奇怪的现象啊!

HalUARTWrite(HAL_UART_PORT_0, ble_To_scale_Serial, ble_To_scale_Serial[1]);

HalUARTWrite(HAL_UART_PORT_0, ble_To_scale_Serial, ble_To_scale_Serial[1]);
