如果想再次配置引脚,可以使用pinsCfg或pinCfg,前者可以配置多个引脚,后者只配置一个引脚。 pinsCfg函数指针的原型如下: /** Configure multiple pins. * @par Implemented as * - @ref R_IOPORT_PinsCfg() * @param[in] p_cfg Pointer to pin configuration data array. */ fsp_err_t (* pinsCfg)(iopor...
This limitation prevents using multiple setup functions which set output pin directions, since they will interact with each other. I will merge all the separate setup functions into a BOARD_InitPins() function to allow the pin setup to be correct. 0 Kudos Reply 09-04-2019 ...

I am integrating a new system which will have a custom board but in the meantime I am using the eInfoChips C6657 EVM. I have two interrupt sources connected to GPIO15 and GPIO14 via the Debug Header pins 78 and 80. Individually either GPIO will work as an interrupt as desir...
imx_iomux_v3_setup_multiple_pads(rgb_pads, ARRAY_SIZE(rgb_pads)); //初始化GPIO (3)gpio_direction_output(DISP0_PWR_EN, 1); //输出高电平 以上部分代码,【迅为IMX6Q】提供的uboot代码里已经实现了。通过了解GPIO的PIN脚定义与操作,如果自己想控制一个GPIO,应该有思路了。
(GPIO.BCM) # 指定 GPIO 针脚为一个电流输出针脚 GPIO.setup(PIN, GPIO.OUT) # 输出低电平 GPIO.output(PIN, GPIO.LOW) # index i = 0 # 类型转换,str => int n = int(arg1) print("n =", n) print('开始闪烁⏳') while (i < n): print("i =", i) # 高电平,LED 点亮 GPIO....

The Jetson GPIO library provides four ways of numbering the I/O pins. The first two correspond to the modes provided by the RPi.GPIO library, i.e BOARD and BCM which refer to the pin number of the 40 pin GPIO header and the Broadcom SoC GPIO numbers respectively. The remaining two mode...
GPIO pins have multiple names; the first most obvious reference is their “physical” location on the GPIO. Starting at the top left of the GPIO, and by that we mean the pin nearest to where the micro SD card is inserted, we have physical pin 1 which provides 3v3 power. To the right...
You can see an example of a correct setup ribbon cable with a T-type breakout board right below. Programming with the Raspberry Pi GPIO Pins Programming with the GPIO pins on the Raspberry Pi is typically done using the programming language Python. This particular circuit and code are super ...
