When using PICC 9.65 to compile a program larger than 2K, the program pointer will run away, but it will be fine if it is less than 2K. I searched online and found that the versions downloaded online ...
The following is the program. When downloaded to the board, it cannot change once a second. It only changes once every 8 seconds. #include
typedef unsigned char uint8; typedef unsigned int uint16; typ...
Why must the coefficient of the first-order term s in the denominator of formula (6.3.14) in the figure be greater than zero for the circuit to operate stably?...
As the title says, I have been in the forum for several years, but I found that my level is still "a grain of gold sand" and that the forum is upgrading so slowly! Is that right?...
1. The heavier the car, the more fuel it consumes From the perspective of fuel saving, the car's own weight is directly proportional to its fuel consumption, that is, the heavier the car, the more fue...
I have used LM5007 as a power supply these days, but I found that the interference is very severe. There is analog sampling on the board, and there are too many high-frequency noises. It is very unsta...
In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer
