..\HARDWARE\INA226\INA226.c(140): warning: #1035-D: single-precision operand implicitly converted to double-precision

回答: 这个警告是由于单精度操作数隐式转换为双精度操作数导致的。在使用STM32F4时，编译器会提示这个警告。解决这个问题的方法有两种。一种是在所有的浮点数字后面加上f，这样编译器就会将其识别为单精度数值，警告就会消失。另一种方法是关闭Target->Floating point Hardware选项。这样可以避免警告，但需要注意关闭该选项可能会影响浮点运算的精度。\[1\]\[2\]\[3\]
