Post by thread:[SX] Programming the SX without a key

In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Philldapill wrote:I'm a propeller user and would like to learn about the SX a little, yet I know very little at the moment. I know there is a simple circuit you can make to program the SX with an RS232 cable - no need for a prop plug. I ordered some SX chips, but totally forgot the SX key. Can I still program it without the key?

However, Guenther's SX-Sim simulator program, which comes free with the free SX-Key IDE, will let you debug the code via simulation. This link is to the SX-Key IDE:
