5.3 SPI支持速率
SPI频率有如下注意事项，其中 F ssi_clk为 pclk，F sclk_in为 spi clock。
➢ SPI Master: F ssi_clk >= 2 × (maximum F sclk_out )
➢ SPI Slave (receive only): F ssi_clk >= 6 × (maximum F sclk_in )
➢ SPI Slave: F ssi_clk >= 8 × (maximum F sclk_in)

按你说增加主频，我现在g_system_clk = SYS_CLK_DLL_64M; 还是不能设置为6.4M，设置6.4M后波形就乱套了

主频64M，spi速率30M。我使用逻分看波形确实乱了。我的逻分100m的，但是用示波器来看没有问题。

请问你发送函数用的哪一个接口？我设置成30M直接回卡死

有做过ws2811驱动预研，以下代码可以参考：

Code: Select all

int ty_light_driver_spi_init(void)//初始化
{
	uint8_t retval = PPlus_SUCCESS;

	hal_dma_init();//use dma
	
	ty_spi_ptr.spi_index = SPI1;
	hal_spi_init(ty_spi_ptr.spi_index);	

	ty_spim_cfg.MOSI = TY2_SPI_PIN_MOSI;
	ty_spim_cfg.baudrate = 7000000;//1bit --- 151ns
	ty_spim_cfg.spi_tmod = SPI_TXD;// only send
	ty_spim_cfg.spi_scmod = SPI_MODE0;
  	ty_spim_cfg.int_mode = false;

我dma的宏手动打开后编译器找不到“include "dma.h"”，我该如何设置路径
