I am a novice in DSP2812, and now I have a question for you experts. Regarding the interrupt service subroutine, in the interrupt service subroutine, the interrupt flag needs to be cleared and the int...
I transplanted the NAND driver of two different CE5.0 BSPs of ATMEL9261 (transplanted the NAND driver of the second BSP to the first BSP, but both are 9261 CE5.0 BSP). After transplantation, the progr...
I just started learning embedded systems. Now I need to use the ADC of the 2440 board to collect sensor data. Since the 2440 does not have an AD conversion driver, I need to write a driver. I wonder i...
I'm working on an SD card upgrade recently. All CMD0, CMD55, ACMD41, CMD2, CMD3, CMD7, CMD55, and ACMD6 can pass and enter the corresponding state. The corresponding response and state are correct acc...
