coolpi 4b python3 gpio operation compatable with raspberry pi

@AugustRobot_Zou
所有的底层封装操作都是基于访问/sys/class/gpio/

请问能麻烦编译一个python3.6.9的安装包吗？
使用CPi.GPIO-1.0.0-cp38-cp38-linux_aarch64.whl，必须装上python3.8。
我的docker环境是ubuntu18.04+python3.6.9+ROS。

装了python3.8后，同时存在python3.8和python3.6，导致原本的代码程序很多python版本适配问题，这几天为这个问题搞得头大，很难兼顾 CPi.GPIO库和原来的程序，模块脚本的#!/usr/bin/python3 只能配置2选1（3.8 or 3.6 )。

@AugustRobot_Zou okay!

@AugustRobot_Zou CPi.GPIO-1.0.0-cp36-cp36m-linux_aarch64.whl

@jack_admin @大法师
Really appreciate your help!
Now our system is basically compatible with coolp4B，which used to running on raspberry-pi4B.

有python3.9版本的吗

[jack_admin]

@xingzhan2012 有。在帖子最顶楼

@jack_admin 谢谢

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:

WiringPi ?

[Macs]

@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

[jack_admin]

@Orion C++可以代码文件操作gpio，不需要调用python库

[Orion]

@jack_admin 请问C++需要包含哪个库呢，是writtingPi吗

[jack_admin]

@Orion 直接裸操作/sys/class/gpio，不做二次包装

[zensation]

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?

[大法师]

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