+Description: STC MCU ISP flash tool
+ stcgal is a command line flash programming tool for STC MCU Ltd. 8051
+ compatible microcontrollers. The name was inspired by avrdude.
+ .
+ STC microcontrollers have a UART based boot strap loader (BSL). It
+ utilizes a packet-based protocol to flash the code memory and
+ IAP memory over a serial link. This is referred to as in-system
+ programming (ISP). The BSL is also used to configure various
+ (fuse-like) device options. Unfortunately, this protocol is not
+ publicly documented and STC only provide a (crude) Windows GUI
+ application for programming.
+ .
+ stcgal is a full-featured Open Source replacement for STC's Windows
+ software; it supports a wide range of MCUs, it is very portable and
+ suitable for automation.
