1, common compilation errors
- error C141: `syntax error near 'extern', expected 'hdata'`
(Error C141: near the "extern" syntax error, should be "hdata")
There are many possible causes of this error, the more common and is difficult to find the time to call in the header file header file is called to write the imperfection causes the compiler to perform under a confusing error.
- *** WARNING : UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
*** Warning: No call segment, covering process ignored
There is a defined function is not called, very common warning
- *** WARNING : MULTIPLE CALL TO SEGMENT
*** WARNING: Multiple calls segmentation
Usually appear simultaneously in the interrupt and calls the main function, the compiler prompt logic errors may occur.
- error C247: non-address/-constant initializer
You can not use a variable to the variable initial value.
- error: L6236E: No section matches selector - no section to be FIRST/LAST.
Error: L6236E: not match the selector's Day - not the first / last section.
No startup files
- Automatic memory allocation setup
*** ERROR L107: ADDRESS SPACE OVERFLOW
SPACE: DATA
SEGMENT: ?DT?SYS
LENGTH: 0004H
*** ERROR L107: ADDRESS SPACE OVERFLOW
SPACE: DATA
SEGMENT: ?DT?_DS1302BURSTREAD?DS1302
LENGTH: 0003HThis is the area keil at compile time you will be automatically stored in the local variables Memory Model set, once too many local variables will generate an error. This time can be set variables stored in PDATA or XDATA, but this will slow down the speed of execution to a certain extent.
2, common logic errors
- In the use of the DAC to be noted that whether the variable will overflow , the output voltage are usually with a decimal point, if 8-bit precision DAC to be noted that it not take a variable type of conversion, in the calculation of recommended or double float type variable type is judged to be cast int type, output type converted to char.
TIPS: cast low security can not be maintained high.
3, common simulation error
Connecting to target system lost！please reset your target system and try again.
