I add following code to my main(), when run it. code stuck. float ft = 3.3; sprintf( str, "%0.2f\n\r", ft );UART0_putString( str );I read the Solved: sprintf not functioning correctly - NXP Communitybut my MDK, uVision IDE, don't have ...
if the buffer is too small for the text being printed then the buffer is set to an empty string and the invalid parameter handler is invoked. 如果写入的数据长度大于 sizeBuffer - 1 ,将会触发错误。 如在vs2010 Debug模式下: 1 2 3
(including the trailing ’/0’). If the output was truncated due to this limit then the return value is the number of characters (not including the trailing ’/0’) which would have been written to the final string if enough space had been available. Thus, a return value of size or ...

Specify Formatted Text as String Array To return formatted text as a string, specifyformatSpecas a string instead of a character vector when you call thesprintffunction. Convert data and return the result as a string. formatSpec ="The current time is: %d:%d %s"; A1 = 11; A2 = 20; A3...
