Since I took over this laser machine trolley project, the car can move, but always crack the plane. These two weeks have been looking for the cause of the crash, and the reason why it is hardware interruption. Interrupt is not as follows, resulting in crash. If you want to change it to accept 8 bytes, you can reduce the number of interrupts. However, there is still a crash after it is changed. Subsequently, the speed of the laser head is lowered, or there is a crash. Diffuse! When I was sleeping yesterday, I thought about this problem, I suddenly thought of "division". Unzid can cause memory overflow. I feel again in the morning, thinking that if one corner is not passed in the filter program, the "divided" is displayed.大! I quickly climb up and rushed to the company. After the change, it was found that there was no crash. I have been looking for this reason for two weeks, the result is because such a small situation is not noticed. Hey ~~~~~~~~~
