解决办法一: make menuconfig,依次进入 Device Drivers GPIO Surport I2C GIPO Expanders 键盘按下y选中PCA95[357]X后,exit到上一次保存;再进入I2C GIPO Expanders选中终端控制器,一直exit保存 解决办法二: …
gpiochip_is_requested 函数是 Linux 内核中用于检查某个 GPIO 芯片(gpio_chip)上的引脚是否已经被请求的函数。 在Linux 内核中,GPIO(通用输入输出)是一种常用的接口,用于控制硬件设备的引脚。每个 GPIO 引脚可以被配置为输入或输出,并且可以被请求(request)和释放(release)。gpiochip_is_requested 函数就是用来检查...
The separate struct bgpio_chip has been a pain to handle, both by being confusingly similar in name to struct gpio_chip and for being contained inside a struct so that struct gpio_chip is contained in a struct contained in a struct, making several steps of dereferencing necessary. Make thi...
