I want to use GPIO to genrate some High / Low signal, but I can not keep the previous signal before change for example, I define the signal : static adl_ioDefs_t GpioConfigL = ADL_IO_GPIO | ADL_IO_DIR_OUT | ADL_IO_LEV_LOW ; static adl_ioDefs_t GpioConfigH = ADL_IO_GPIO | ADL_IO_DIR_OUT | ADL_IO_LEV_HIGH; # I use two gpio to indicate the tow signal, ; MyLedGpioConfig = GpioConfigL | Led_Gpio_Label [ 0 ]; MyLedGpioConfig = GpioConfigH | Led_Gpio_Label [ 1 ]; # use io write to generate gpios signal
sReturn = adl_ioWrite ( MyGpioHandle, LED_COUNT, MyLedGpioConfig );
after writing, the Q2687 only generate a pulse, which was measured by oscilloscope , the gpio pin can not keep the wrote signal level,
Does any body can tell me how to keep the writing level? Is there any other write method to implement it?
