这个驱动是不是不支持stm32hal库的spidma函数呢 #23
Comments
LibDriver W25QXX支持STM32HAL中的SPI_DMA传输,本库单个功能函数执行代价都很低,因为芯片命令比较多,本库对所有命令都有支持,造成代码比较多。无法触发中断可能与整个工程系统各类外设优先级分配、DMA驱动等有关,您需要提供更加详细的SPI_DMA驱动等信息,我们会帮助您一起排查问题。 |
为了有效的排查问题,我们可能需要更加详细的信息。如果可以的话,请您将您的工程脱敏,把整个脱敏工程发给我们([email protected]),这将有助于我们全面排查问题。如果因为安全等问题无法脱敏整个工程,请您至少把stm32f107与LibDriver_W25QXX接口实现文件以及DMA配置等相关文件发送给我们,这对我们全面分析问题很重要。 |
好的,稍后我会将工程发送给你 |
我已经将工程发送给你的邮箱了,请查收 |

使用我将之前的阻塞的spi函数换成了dma函数,发现一直触发不了中断,然后我另外使用一个工程,直接使用dma操作,发现是可以的,是不是因为这个库封装的太多导致的问题呢?
