hi
i can help you to translate the documents to persian, how can i help you?

I have made a simple parallel interface eeprom dumper (writing could also be implemented) with parts lying around some time ago, might be useful for some people

Requires 1x ch341a and 2x MCP23017 (i2c)

https://github.com/DSchndr/ch341a_parallelprog

I tried compiling the sample code but had difficulties mainly due to the lack of android developer support for the eclipse IDE:

The Eclipse ADT plugin is no longer supported, as per this announcement in June 2015.
The Eclipse ADT plugin has many known bugs and potential security bugs that will not be fixed.
You should immediately switch to use Android Studio, the official IDE for Android. For help transitioning your projects, read Migrate to Android Studio.
Ref.: https://developer.android.com/studio/tools/sdk/eclipse-adt#installing

I noticed that the sample code uses:

• Android 4.1.2 (API 16), (only need SDK packages, can skip large image files) and
• Android SDK Build-tools 24 (Android SDK Build-tools 26 do not works).

It would be interesting if the example were updated to be compiled with new Android Studio 3.

Hello,

I tried to use your CH341PAR_LINUX driver under Linux 4.19. I managed to compile and load the module properly (an include is missing for this kernel version btw). I am using it with the LC-Technology module.

However I get inconsistent information while using CH34x_GetVendorId. You can see below the kernel traces of 2 subsequent calls:

[32884.966386] /home/test/CH341PAR_LINUX/driver/ch34x_pis.c 874: CH34x_GET_DRV_VERSION Successed
[32884.966424] /home/test/CH341PAR_LINUX/driver/ch34x_pis.c 197: VENDOR_READ_TYPE: 0x5f : 0x0 : 0x0 -11 - 2
[32884.966434] /home/test/CH341PAR_LINUX/driver/ch34x_pis.c 885: ------> 2 Chip Version is sucessful 0xffffffb0ffffff93

[32897.046547] /home/test/CH341PAR_LINUX/driver/ch34x_pis.c 874: CH34x_GET_DRV_VERSION Successed
[32897.046585] /home/test/CH341PAR_LINUX/driver/ch34x_pis.c 197: VENDOR_READ_TYPE: 0x5f : 0x0 : 0x0 -11 - 2
[32897.046595] /home/test/CH341PAR_LINUX/driver/ch34x_pis.c 885: ------> 2 Chip Version is sucessful 0x6b3

Furthermore, a call to CH34xSetStream for instance leads to a kernel crash.

Any ideas of what is wrong?

Hello, I noticed that the guide is not fully translated into English. I tried translating with google to understand how it works, but may need to be reviewed, Follows attached.

(Note: Edited with WPS office)

The CH341 is a USB bus adapter that provides asynchronous UART, parallel port, and common 2-wire and 4-wire synchronous serial interfaces via the USB bus. In the parallel port mode, an EPP/MEM 8-bit parallel interface is provided, and the commonly used synchronous serial interface mainly includes a 2-wire IIC, a 4-wire SPI, and the like.
This document mainly introduces the Java Driver Library of CH341USB to EPP, MEM, IIC, SPI mode (hereinafter referred to as CH341PAR), and how to use the APK to operate CH341PAR for data communication under Android. The driver is based on the Android USB Host protocol, and the user can call the provided interface API to communicate with the Android USB Host.

This version seems to be clean and does not contain anything extra
v1.13

it may work with your CH341A programmer or may not. but at the very least this is a clean-ish copy that i could find

there also appears to be flashrom for windows

Just found another open source ch341a programmer: https://github.com/McMCCRU/SNANDer

Your file https://github.com/boseji/CH341-Store/raw/master/WORKING-CH341A-programmer-software-1.29.zip contains a trojan according to Avira antivirus.

what do I do now?
I have GD25Q64C bios from mainboard biostar tb250.
