1. First of all, whether the LED is damaged or not is just a concept.
2. When Q2 is not present, Q1 is saturated.
3. The key is Q2Ub = 1.3VUc = 9VA classmate said that the transistor CE can be replace...
I have been using interrupt nesting recently. I have not used 5509 external interrupts much before. I have tried 5509 external interrupt nesting these days, but the results are not ideal. Either there...
