MCU：ATMEGA8515

Frequence: 16M

描述：利用已有CAN TEST V1.0电路板进行调试,

可靠性测试已通过，并发现8515外部中断不稳定

的原因是没有在INT0脚加上拉电阻，加上后已能

够稳定地运行

调试过程中发现SJA1000的首地址设置有误，改过

后，当CAN发送数据时，程序能进入中断了，但发现

中断是由出错报警中断引起的，估计与波特率设置

有关。

通过修改CDR的参数，以及更换16M晶振，现在已能

正常地收发送数据了-MCU : ATMEGA8515 Frequence : 16M Descr iption : make use of the existing CAN TEST V1.0 circuit board debugging and reliability tests were passed, 8515 and found that the external interrupt instability is not in INT0 feet with pull-up resistors. after adding stability to the running debug process SJA1000 found in the first set addresses wrong, to turn over, When CAN send data, the program can enter the interruption, but the interruption was discovered by police errors arising from the interruption, estimates and baud rate settings. CDR by modifying the parameters, and the replacement of 16M crystal, it is now normal to send data admission!
