Hi Allison, Thanks for your reply! I have seen this doc and it says ' Depending on the version of the compiler, calling one of the *printf functions requires more than 400 bytes of stack. Make sure the stack is in valid read/write data memory.'. Does it mean if i need to call 17 sprintf function, i need to prepare more than 6.6kB stack for it? It's too large, and we don't have enough stack. Or do C2000 lib have some function to convert float data into chars? Best Regards, Jim
