Other Parts Discussed in Thread: C2000WARE,
Tool/software:
Hello, engineers. We are currently working on creating a learning guide for the F28P550. However, we have encountered a problem when using the floating-point data format string.
Version environment: Windows 11, CSS 20.1.1.8__1.7.1, C2000Ware_5.04.0.00;
Neither the projects created through CCS nor the routines in C2000Ware can utilize the %f formatting function of the standard C library. Any floating-point operation involving %f will cause the system to freeze.
For example, in the code use:
printf("%.2f\r\n", 12.1);
sprintf(buf, "%.2f\r\n", 12.123);
Single-step debugging through the XDS110 debugger reveals that the program gets stuck and does not execute the task when it reaches the above code. However, the XDS110 can still control the chip to reset.
Tried solutions:
1. Add include<stdio.h>, stdlib.h
2. Increase stack 0x400 0x400
3. Enable the project's --printf-support = full
All failed.
Although other custom functions can be used in the code to solve the problem of outputting floating-point data, it would be rather cumbersome. It is more desirable to directly format it as a string using %f.
Could you please share any ideas about the usage of %f?
