Changes

Added line
#include <linux/sched/signal.h>
which helps to fix the problem below:
error: implicit declaration of function ‘signal_pending’; did you mean ‘timer_pending’? [-Werror=implicit-function-declaration]

and changed line:
wait_queue_t wait;
to
wait_queue_entry_t wait;
which helps to fix next problem below:
error: unknown type name ‘wait_queue_t’; did you mean ‘wait_event’?


Additionally first pull request helped to merge changes for version 1.5 released in 2018-03-18:[https://github.com/juliagoda/CH341SER/pull/1](https://github.com/juliagoda/CH341SER/pull/1)

Tested for Arduino UNO R3 Clone

install required packages:
sudo pacman -S arduino arduino-docs avr-binutils avr-gcc avr-libc avrdude


if your system detects the package below:
pacman -Qs arduino-avr-core


you should remove it:
sudo pacman -R arduino-avr-core


we add current user to uucp and lock groups:


it's possible, that you have to load that module:
modprobe cdc_acm


clone fixed driver:
git clone https://github.com/juliagoda/CH341SER.git


according to the original readme.txt, we use the commands below:


to be sure, that module will be loaded after reboot, you can change file extension from '.ko' to '.ko.gz' and add it to drivers path:


if the command:
lsmod grep ch341


shows some result, then:


let's connect Arduino UNO R3 Clone to USB input and check our results:
dmesg grep ch34x


that's example of my command's output:


so our driver ch34x was successfully loaded and our port's name is ttyUSB0
Let's start our installed Arduino IDE.
First we should install package for Arduino AVR Boards from Boards Manager:


And now we must choose our port's name. My port's name is ttyUSB0.

Ch341ser Driver Windows 7


Why we wanted arduino-avr-core package from official repo to be removed? Let's check it out.

sudo pacman -S arduino-avr-core


and let's reopen our Arduino IDE and check out boards list.


New label 'Arch Linux Arduino AVR Boards' with boards has been added to boards list. It has the same options, so let's choose 'Arduino/Genuino Uno' from a new part and upload our code to Arduino UNO R3 Clone.


It didn't work. I think, that the package was created for original arduino boards, which are not compatible with their clones. If you want to have installed the package and work on clone of Arduino, better choose the same option from part labeled 'Arduino AVR Boards'.


Compatibility

This driver is not compatible with the Olimex ESP32-POE rev C board
