## README

# 基于CH552G的USB BLASTER固件，支持AS接口，支持硬件SPI实现的JTAG，新驱动不闪退。

# USB-Blaster Firmware for "REV. C USB BLASTER" board with CH552G chip.

This is a fork of [CH55x-USB-Blaster firmware by VladimirDuan](https://github.com/VladimirDuan/CH55x-USB-Blaster) that runs on a cheap clone Altera USB Blaster with CH552G chip.
It works correctly in Linux and Windows with my limited testing(I am testing with MAX V CPLD), no special drivers required.

#
- This fork added all needed files for correct build.
- Implement CI to build and release binary files so you don't need to setup or download any build tools or sdk files.
- Support AS mode.
- Support hardware SPI now.

#
CH552G can be replaced by CH551G and CH554G, in fact these models have the same Die.

|   NCE   |  P3.4  |

Under normal circumstances, the JTAG interface is able to be compatible with the AS interface.
