GPIO 速度等级设置。 输入状态:浮空,上拉/下拉,模拟。 通过输入数据寄存器(GPIOx_IDR)或者外设(GPIO 设置为复用模式)输入数据。 通过寄存器GPIOx_BSRR 实现对寄存器GPIOx_ODR 的位操作。 通过配置寄存器GPIOx_LCKR 的锁机制,实现冻结IO 口配置。 每两个时钟周期就可以翻转一次IO。 高度灵活的引脚复用功能,允许IO...
to a gpio_config_t variable, specifically stating that I want a PULLUP on an Output pin, AND AND, having an external pull up resistor 1K (for good measure in case the pin does not have a pull-up), when the call is made to the gpio_config(&io_conf) the pin goes immediately LOW...
1.1.GPIO在sys_config.fex 中的定义 在对应方案中的sys_config.fex 可以找到许多的GPIO 定义,具体说明如下: ;———-; [gpio_para] creat a new mainkey to introduce the gpio usage;———-[gpio_para]gpio_test0= port:PE12<1> 以gpio_test0 为例,配置参数解释如下: gpio_test0 = port:PF02<3...

im trying to route pin 1 with gpio_config(config) and esp32 hangs on this command. Code: Select all uint64_t mask = 2; gpio_config_t config; config.pin_bit_mask = mask; config.mode = GPIO_MODE_INPUT_OUTPUT; // <-- all combinations here config.pull_up_en = GPIO_PULLUP_ENABLE...
Hi,guys! when I build a pthon3 script with gui and GPIO contorl.I can run it when I use terminal with sudo command. But when I used "settings->session and startup" to config this script,It can't run when my device reboot (Orange Pi PC). I try to config c
ROM_GPIOPinConfigure我认为操作的不是gpio的寄存器,操作的是对应的外设功能的寄存器。 ROM_GPIOPinTypeGPIOOutput、ROM_GPIOPinTypeUART这种操作的是gpio的寄存器,配置IO的方向、电流、模式等。 对应的函数原型可以在库中的gpio.c中可以找到。 我们其实记住常见的用法就好了,配置为特殊功能,非普通IO...
