Can somebody suggest me a program like PROTEUS where I can test my hex file too? Because Proteus does not work as I expected

 

Can you give us a bit more explanation.... What chip are you using?
8051... You can use MCU8051IDE
AVR... Loads of simulators
Pic... Oshonsoft

 

And what does "does not work as I expected" mean? Perhaps it is just your design that is at fault?


In the future please use a more descriptive subject line. "Very strange" says noting about your message.
