i use kiel compiler to obtain a hex code.
but i wanna be sure about one thing. in the kiel program, when i convert c in hex code, ( this is the adress in program “Project/ Option for Target ‘Target one’/ Xtal (MHz)”) the default value for Xtal is 24 Mhz. In the schematic we use a 12 Mhz crystal. I must to change this value to 12 Mhz, or just leave it at 24 Mhz?
