            Does the coolpi have a DPI mode for the gpio like the RPI4?

              @Macs said in coolpi 4b python3 gpio operation compatable with raspberry pi:

              Does the coolpi have a DPI mode for the gpio like the RPI4?

              WiringPi ?

                @jack_admin I mean can output video signal on the gpio using with custom timings, like you can on the RPI4?

                    @Orion C++可以代码文件操作gpio,不需要调用python库

                        @Orion 直接裸操作/sys/class/gpio,不做二次包装

                          it says in the GPIO page that all gpio are configurable with pullup or pulldown mode. How can we access the pull down resistor on a input pin say pin 32 GPIO105 that is default set to pullup? I tried the same convention as raspberry pi python access which is

                          GPIO.setup([pin#], GPIO.IN, pull_up_down=GPIO.PUD_DOWN)

                          and i get the error no PUD_DOWN in the module. Can you post the entire documentation with included commands in this module?
