STM32F系列芯片的开发

之前在进行项目研发时候，一直在Keil下进行STM32程序的编程设计，感觉和其它的单片机如51单片机区别不大；但是在网上和企业招聘中经常遇到这样的信息：STM32在linux系统下的编程设计，这两个有什么区别？如果我一直在keil下进行这方面的设计，那么上面的应用下我会怎么样？

使用C8051F的单片机来实现CAN控制，可以进行数据的接收，发送不行 void CAN0_TransferMO (U8 obj_num) { // This function assumes that the message object is fully initialized // in CAN0_Init and so all it has to do is fill the data registers and // initiate transmission U8 SFRPAGE_save = SFRPAGE; SFRPAGE = CAN0_PAGE; // All CAN register are on page 0x0C // Initialize all 8 data bytes even though they might not be sent // The number to send was configured earlier by setting Message Control CAN0IF1DA1H = obj_num; // Initialize data registers based CAN0IF1DA1L = obj_num + 1; // on message object used CAN0IF1DA2H = obj_num + 2; CAN0IF1DA2L = obj_num + 3; CAN0IF1DB1H = obj_num + 4; CAN0IF1DB1L = obj_num + 5; CAN0IF1DB2H = obj_num + 6; CAN0IF1DB2L = obj_num + 7; CAN0IF1CM = 0x0087; // Set Direction to Write // Write TxRqst all 8 data bytes CAN0IF1CR = obj_num; // Start command request while (CAN0IF1CRH & 0x80); // Poll on Busy bit SFRPAGE = SFRPAGE_save; }
