HaawkingIDE新建工程 2. 配置GPIO void GPIO_INIT(){ EALLOW; GpioCtrlRegs.GPADIR.bit.GPIO0 = 1; GpioDataRegs.GPADAT.bit.GPIO0 = 1; GpioCtrlRegs.GPADIR.bit.GPIO7 = 1; GpioDataRegs.GPASET.bit.GPIO7 = 1; EDIS; } 复制代码* 擦除扇区 Uint16 erase(int sector_idx){ Uint16 Status; Status = Flash28027_Erase(sector_idx, &FlashStatus); if(Status != SUCCESS) return FAIL; else return SUCCESS; } 复制代码向flash中烧写数据 Uint16 flash_program(Uint32 FlashAddr, Uint32 BufAddr, Uint32 Length, FLASH_ST FProgStatus){ Uint16 Status; Status = Flash28027_Program((Uint32 ) FlashAddr, (Uint32 )BufAddr, Length, FProgStatus); if(Status != SUCCESS) return FAIL; else return SUCCESS; } 复制代码* 3. main函数 int main(void) { int temp,in; volatile unsigned int i; Uint16 status; FLASH_ST FlashProgStatus; DisableDog(); InitSysCtrl(); //12MHz //We shall Unlock the chip when running from JTAG Mode //CsmUnlock(); GPIO_INIT(); //Erase 62th Sector status = erase(62); //Write Buffer[LEN] to 62th Sector, From the beginning Address,0x73F000 status = flash_program(Sector[62].StartAddr,Buffer,LEN,&FlashProgStatus); temp = 0; for(i=0;i //Read form 62th Sector, check whether we have written correctly if((Uint32)(Sector[62].StartAddr + i) != Buffer[i]) temp++; } while(1){ if(temp == 0) { GpioDataRegs.GPACLEAR.bit.GPIO7 = 1; //D400亮数据对比成功 } else { GpioDataRegs.GPADAT.bit.GPIO0 = 0; //D401亮数据对比失败 for(i=0;i<120000;i++); GpioDataRegs.GPADAT.bit.GPIO0 = 1; for(i=0;i<120000;i++); } } return 0; } 复制代码 4. 点击编译、编译完成后点击下载 5. 运行结果：D400灯亮数据烧写成功，D401灯亮数据烧写失败。 0
