将SPI1->CR1的中间3位设置为1.至于什么意思去查下SPI1->CR1的每个位的功能.
If SPI _SR TFFF is not setten up there is no DMA hardware request. I have tried to solve that problem by another channel linking(2DMA channel to send data to 1 SPI) but SPI_SR has fields that protected from writing so I got a bus error. If you know how to solve that i will ...
(SPI1->SR & 0x01 yijie692 2018-10-01 19:32:40 用spi操作nrf2410时手册推荐程序不一致是为什么? =SPI2_ReadWriteByte(0XFF);//notice !NRF24L01_CSN = 1;return(reg_val);} 战舰的实现是SPI2_ReadWriteByte(0XFF);但说明手册的推荐程序是SPI2_ReadWriteByte(0); 请教原子哥这是怎么回事呢?
