 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? 
- 
 请问支持C++语言吗 
- 
 @Orion C++可以代码文件操作gpio,不需要调用python库 
- 
 @jack_admin 请问C++需要包含哪个库呢,是writtingPi吗 
- 
 @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?

 @zensation not support setting pullup/down in user space now.
