I have a Real-time c51 program, I need a large buffer(120 bytes).Now I use the data segment space, but when I link it an error will appear: "Address space overflow, Length: 001DH". I do not want to use xdata space like: xdata BYTE buf[120], because this type data will affect the executive speed, can I set a large data space? Now I use the uVision/51 for windows Version 1.32. Thanks very much! Tom wu
If you are using an 8051-based part, which has 128 bytes of internal RAM, you could consider an 8052-based part, which has 256 bytes of internal RAM. --Dan Henry
