I used the microcontroller to transplant UCOS-II to create a semaphore. When OSTaskQuery is not used, OSSemPend and OSSemPost can be called normally, and the return value is OS_NO_ERR. After using OST...
Which communication method takes up less resources? I use a parallel bus, which takes up too many resources. XC2C256 only has one bus and it takes up all the resources.
I don't know how much resources...
