if(Bianxing[0]>0) Bianxing[0]--; There are two sentences in the program. The array Bianxing[6] is long int. When debugging, I found that if Bianxing[0]=1, it will become 0XBF80000 after decrementing. ...
There is a question I have always wanted to ask. In a circuit board, if I have already filtered the wave at the power supply and processed it, can I add a few less capacitors at the MCU? For example, ...
Design for testability (DFT) is the least valued of all the electronic design automation (EDA) tools on the market, even though improving the testability of chips during the design phase will signific...
S5PV210 Introduction S5PV210 is a microprocessor based on ARM Crotex-A8 architecture 32-bit CPU. It has 32 address lines and 32-bit data lines. The 32 address lines determine that the CPU address sp...[Details]
Recently, a project based on LPC23xx needs to reset and restore to factory settings at the same time with one button (similar to using a thin needle to poke a hole on some ADSL and routers). I implem...[Details]
At present, China's garbage classification work is being accelerated, and by the end of this year, 46 key cities will basically have established garbage classification and treatment systems. Recent...[Details]
