Ch341Prog

A simple command line programmer tool for interfacing with ch341a under Linux and macOS.

Description

There are a lot of cheap SPI/IIC programmers based on ch341a which can be bought online for as low as $3. However, there were no Linux-based tools associated with the hardware; the best I could find was a tool called ch341eepromtool (original link dead), which could only deal with IIC EEPROMs. So, I decided to write my own.

After reading the source for ch341eeprom and sniffing the USB traffic, I believe I have fully understood the USB protocol. Here is what I have got so far.

Special thanks to asbokid, the ch341eepromtool’s author. Please see the CONTRIBUTORS file for a full list of people who helped build this.

Hardware Permissions

To access the CH341A programmer as a non-root user, you must install the appropriate hardware rules for your operating system.

Linux (udev)

Run the following command to install the udev rule file into /etc/udev/rules.d:

sudo make install-rules

FreeBSD (devd)

Run the following command to install the devd configuration file into /usr/local/etc/devd:
