#84200 - Data Sizes - Lesson not yet learned? Responding to: ???'s previous message |
In you previous thread:
http://www.keil.com/appnotes/docs/apnt_161.asp one unanimous recommendation was that you need to carefully consider your variable sizes for an 8051 target. You are still using a lot of 'int' variables where you don't need to; eg, IsLeapYear() can only return either 0 or 1, but its return type is 'int' - which is 16 bits in Keil C51! A the very most, this should be 'unsigned char'; and preferably 'bit'. Note also that the 8051 has no native support for signed arithmetic - so signed variables should also be avoided unless specifically required. |
