我想用DMA传输浮点数据但是总是传输不了啊 volatile Uint16 DMABuf1[BUF_SIZE]; volatile Uint16 *DMADest; volatile Uint16 *DMASource; 改成 volatile float DMABuf1[BUF_SIZE]; volatile Uint16 *DMADest; volatile Uint16 *DMASource; 之后 DMADest = &DMABuf1[0]; DMASource = &AdcMirror.ADCRESULT0; DMACH1AddrConfig(DMADest,DMASource); 这儿总是报错 说是a value of type "volatile float *" cannot be assigned to an entity of type "volatile Uint16 * 我知道是指针类型有问题 但是如果想用DMA传浮点型数据的话该怎么改啊？ 是不是哪儿还要设置啊
