更新内容如下： C51 Version 9.51 Release - [New Supported Devices]
- Silicon Laboratories Inc.
C8051F370, C8051F371, C8051F374, C8051F375, C8051F390, C8051F391, C8051F392, C8051F393, C8051F394, C8051F395, C8051F396,
C8051F397, C8051F398, C8051F399, C8051T620, C8051T621, C8051T622, C8051T623, C8051T626, and C8051T627.
- [Cx51 Compiler]
- Corrected: calculation of negative constants within nested calls may create incorrect results (this problem was introduced in C51 V9.50a). For example: #define TDO 5#define GET_TDO() (Arr[TDO])unsigned char xdata Arr[10];unsigned char TestTDO() { unsigned char ret; ret = (unsigned char)(((GET_TDO()-1)*2)-1); // Incorrect result. For the negative constant a subtraction has been used instead of an addition. return ret;}
- Corrected: incorrect pointer arithmetic with subtract of unsigned int variables for XDATA arrays with sizeof < 256 bytes. For example: unsigned char xdata b[256]; /* Problem does not exist when array size > 256 */void xdata *p;unsigned int i = 256; /* Problem only appears for unsigned int variables */void main (void) { p = &b[256-i]; /* Works no problem when array index is used */ p = b + 256 - i; /* Failed on pointer arithmetic when uint variable is subtracted */}
- [LX51 Linker/Locator]
- Corrected: a potential DPTR corruption which may occurs in code-banking applications when Global Register Coloring is enabled.
- [μVision]
- This C51 release comes with μVision V4.60.6.8.
- Enhanced: the Logic Analyzer allows rearranging signals through a simple drag&drop of the signal name. Signals can be scaled in width and height.
- Corrected: under certain circumstances the Source Browser incorrectly reported several definitions of an "enum".
- Refer to uVision Revision History for a complete list.
