Please somebody help me?
I am trying to write simple led code but ı got error build output is
Build started: Project: Proje*** Using Compiler 'V5.06 update 6 (build 750)', folder: 'C:\Keil_v5\ARM\ARMCC\Bin'Build target 'Target 1'linking....\Objects\Proje.axf: Error: L6218E: Undefined symbol assert_param (referred from misc.o).Not enough information to list image symbols.Not enough information to list load addresses in the image map.Finished: 2 information, 0 warning and 1 error messages.".\Objects\Proje.axf" - 1 Error(s), 0 Warning(s).Target not created.Build Time Elapsed: 00:00:00
---------------
and my code is:
#include "stm32f4xx.h" // Device header#include "stm32f4xx_gpio.h" // Keil::Device:StdPeriph Drivers:GPIO#include "stm32f4xx_rcc.h" // Keil::Device:StdPeriph Drivers:RCC
int main(){ GPIO_InitTypeDef GPIO_InitStructure; //Configurations hiding below the structure of TypeDef RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOD,ENABLE); GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT; GPIO_InitStructure.GPIO_Pin = GPIO_Pin_12 | GPIO_Pin_13 | GPIO_Pin_14 | GPIO_Pin_15 ; GPIO_InitStructure.GPIO_OType = GPIO_OType_PP; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz; GPIO_Init(GPIOD,&GPIO_InitStructure);
GPIO_SetBits(GPIOD,GPIO_Pin_12); GPIO_SetBits(GPIOD,GPIO_Pin_13); GPIO_SetBits(GPIOD,GPIO_Pin_14); GPIO_ResetBits(GPIOD,GPIO_Pin_15); }
it is best answer thanks a lot
