The DDR Tackle (4 bytes in PRU0 memory 0x00000004) – this worth is The bottom address with the DDR exterior RAM pool so the PRU0 can compose directly to this memory Place in an effort to retailer sample data.
One example is, when you style, the keyboard controller (the components device that manages the keyboard) challenges an electrical sign to your processor to inform the operating method to recently offered crucial presses.
The 1st two functions disable a given interrupt line for all processors while in the interrupt controller.
The only way to accomplish considerably quicker sample fees could be to use a parallel ADC, which might itself create issues with Improved GPIO availability. The rate can be pushed to approx. one.5MSps with this particular software, but I don’t think that a much better sample costs are achievable with my code composition — Maybe 2MSps at most!
The kernel generally should immediately copy the networking packet into principal memory since the community facts buffer around the networking card is mounted and miniscule in dimensions, significantly when compared to principal memory.
Listing 13.A2: The PRUADC.c Program Listing (remember to Observe which you could expand or open the code in a brand new window utilizing the controls in the best-appropriate from the Screen box)
