Where can I download a free 8052 or AVR simulator? I downloaded astudio 3 from ATMEL products but I can't get the simulator to work.
I also have the problem that I have only a homemade programer. Which pins on the serial port have to be raised high in order to get rid of "no device detected". The programmer might be able to take of the rest. When the 8515 is programed be an effective assembler that was written, ussually the program runs.
