现在我在设计中发现IO不够用,想把D0-D4用作常用的GPIO,请问需要在哪里设置?? 看资料D0为GPIO7 D1为GPIO8 D2为GPIO9 D3为GPIO10;现在设置为GPIO后,就会引起重启!

Code: Select all

#define SPI_CLK_GPIO_NUM                            6
#define SPI_CS0_GPIO_NUM                            11
#define SPI_Q_GPIO_NUM                              7
#define SPI_D_GPIO_NUM                              8
#define SPI_WP_GPIO_NUM                             10
#define SPI_HD_GPIO_NUM                             9
你用的这几个引脚接的是SPI-flash

我看到ESP32-WROOM-32D外引的IO口只有22个脚,有不有模块的IO口外引出来的多些??
