[求助]TA RMP
<p>你好！</p><p>我用Ti的28335的CAN控制模块作为控制器，下面是一段发送程序以及初始化的程序，我不能理解得是，清除TA，还怎么给TA赋值1呢，再在初始化是，清除寄存器TA,RMP,GIF时，也是赋值为1，我刚学C语言，也刚接触这方面，不是很明白，望解答，先致谢！</p><p>/* Begin transmitting */<br/>// while(1) // Uncomment this line for infinite transmissions<br/>for(i=0; i < TXCOUNT; i++) // Uncomment this line for finite transmissions<br/>{<br/>ECanaShadow.CANTRS.all = 0;<br/>ECanaShadow.CANTRS.bit.TRS5 = 1; // Set TRS for mailbox under test<br/>ECanaRegs.CANTRS.all = ECanaShadow.CANTRS.all;<br/>while(ECanaRegs.CANTA.bit.TA5 == 0 ) {} // Wait for TA5 bit to be set..<br/>ECanaShadow.CANTA.all = 0;<br/>ECanaShadow.CANTA.bit.TA5 = 1; // Clear TA5<br/>ECanaRegs.CANTA.all = ECanaShadow.CANTA.all;<br/>loopcount ++;<br/>}<br/>}</p><p></p><p></p><p>// TAn, RMPn, GIFn bits are all zero upon reset and are cleared again<br/>// as a matter of precaution.<br/>/* Clear all TAn bits */<br/>ECanaRegs.CANTA.all = 0xFFFFFFFF;<br/>/* Clear all RMPn bits */<br/>ECanaRegs.CANRMP.all = 0xFFFFFFFF;<br/>/* Clear all interrupt flag bits */<br/>ECanaRegs.CANGIF0.all = 0xFFFFFFFF;<br/>ECanaRegs.CANGIF1.all = 0xFFFFFFFF;</p>页:
