Today I passed by the place where I used to live in the school (to take some sundries from my sister's house). It has been demolished for a long time. Now I am dragging old bricks after the busy farmi...
I want to use conditional compilation in assembly language, similar to the if-else structure in C. However, the book requires that the expression after .if must be complete. When I use .if AA=0 in my ...
I calculated a byte on SPI (C language), calculated 4 bytes on DSP (assembly), and then sent the 4 bytes on DSP to SPI one by one for comparison. If the first byte sent is the same as the byte on SPI,...
STM32F103RC WWDG does not reset:use the IAR routine,/* WWDG clock counter = (PCLK1/4096)/8 = 244 Hz (~4 ms) */WWDG_SetPrescaler(WWDG_Prescaler_8);/* Set Window value to 65 */WWDG_SetWindowValue (65);/...
I am currently studying and I think I have a good programming foundation. I want to learn Windows kernel driver development. However, I have only learned a little from the book. Since I don't have spe...
