stcgal - STC MCU flash tool
|
|
===========================
|
|
|
|
stcgal is a command line flash programming tool for STC MCU Ltd. [1]
|
|
8051 compatible microcontrollers. The name was inspired by avrdude [2].
|
|
|
|
STC microcontrollers have a UART based boot strap loader (BSL). It
|
|
utilizes a packet-based protocol to flash the code memory and IAP
|
|
memory. 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 replacement for STC's Windows software;
|
|
it is very portable and suitable for automation.

Supported MCU models
|
|
--------------------
|
|
|
|
stcgal should fully support STC 89/90/10/11/12 series MCUs. STC
|
|
15 series handling is unfinished, but should work with
|
|
STC15F10x/STC15F20x MCU models.
|
|
|
|
So far, stcgal was tested with the following MCU models:
|
|
|
|
* STC89C52RC (BSL version: 4.3C)
|
|
* STC12C5A60S2 (BSL version: 6.2I)
|
|
* STC11F08XE (BSL version: 6.5M)
|
|
* STC15F104E (BSL version: 6.7Q)
|
|
|
|
More compatibility testing is going to happen soon.
