Hi Oliver,

thank you for your explanation.


> in graphical ...

This sounds an additional step (graphical description) between my brain and the code and so an additional source of posibility of errors.

Also I believe, this work only on the simple standard 8052 SFRs.
More complex functions (e.g. CAN on the C505, I2C on the 80C652) seems not realistic to be verbose described in a graphical manner.


> mouse-clicking advantage

Its not an advantage for me, since typing a character is always faster, as searching a defined position on the screen and clicking.


> stack overflow check

If this really can be done, this was worth the Nobel prize.

The only solution, that I found: Initialize the whole stack with a known pattern and make a RAM dump after a long time of real time execution.
On my C51 programs I try to have 8 ... 16 bytes untouched.


> switching around different x51

Seems I must then also switch between different APP Builders ?
E.g. I use now: AT89S8252, DS80C320, C505, 80C652, 87C751


I believe not, that all niceties, included in a few hundred pages of the data book, can be placed on the screen.
