we are using nucleo STM32F429ZI (Cortex M4 uC ) running with the following configurations.Compiler : Keil, TruestudioFreq : 168MHzFPU : Single HardwareOptimization: O3 in keil, Os in truestudioWe have tested the user generate...
When we select used -mfloat-abi=hard in keil5, it says unrecognized option. I have attached images for your reference. When we select FPU in true studio, -mfloat-abi=hard is added automatically.
Thanks JWThe FPU is already being used.As you told the floating point constants are suffixed by 'f', Also sin and cos are suffixed with 'f'.Now the execution time gets reduced to 15ms. Is it possible to reduce furthermore.
