Surge voltageWhen a circuit is struck by lightning and when an inductive load or a large load is connected or disconnected, a high operating overvoltage is often generated. This instantaneous overvolt...
I have already converted the hexadecimal value of Chinese characters into GB2312 code, and now I want to convert the code into UTF-8 code. How can I do this? Please help me write a code and give me so...
When using a DSP (I have a 5502) with an external port EMIF to connect to external expansion memory, do I need to consider the address shifting problem? I read the data sheet, but I am a little confus...
My timer 0 is set as follows, but it can't enter the interrupt when running. Is there something wrong with the setting?void timer0_init(void) {rSRCPND = rSRCPND | (0x110); //Clear timer 0 source reque...
