why can't support stc89c52
stcflash is a great project, thank you for your work!
But when I try to use it dowmload program for stc89c52 mcu, it doesn't work, blocking at "Detecting target...".
I want know why stcflash doesn't support stc89c52, Is it possible to support stc89c52?
And my second question is how do you find the protocols for these mcu?
Add support to erase eeprom
Would you add support to erase eeprom?
Thank you.
Read flash
Hi!
It seems like currently there is no way to read flash from the device (this feature is not available even in their own tool).
However, I really need this feature for one of the projects I'm working on.
Perhaps there is a way to implement it? E.g. maybe the verify sequence can be abused to get the data?

STC15L2K60S2

经查，是因为本款芯片ROM过大导致，而原程序timeout时间为1s，擦写时间不足，所以引发报错。
解决方案：
修改源程序第170行，增加timeout时间，这里设置为5s
170 def recv(self, timeout = 5, start = [0x46, 0xB9, 0x68]):
171 timeout += time.time()
172 while time.time() < timeout:

It is possible?
thanks!
Can itsupport STC12C5A60S2?

I got an IOError
I just want to detect some info of my 89c52, but always raise an IOError.
it's my steps to use this script.
1st,python stcflash.py;
2nd,turn off the power;
3rd, turn on the power.then wait.then raise error.
why...
Is this possiable to flash the lastest stc mcu ,like 'stc15' or 'stc8'?
Althought it work fine for stc89,stc90,stc12 .Is this also work for the lastest mcu ,like 'stc15' or 'stc8'?
it is time to update it to py3
to be honest for anyone wants to flash code into 8051, linux is great option for studying hardware, thus it is worth to update it to python3, as long as related modules
