Kind Code: A1 Abstract: A method is disclosed for generating a sequential pattern of motor control instructions under control of a microcontroller for the purpose of controlling a motor. A pattern of motor control instructions is stored in a memory. A timing circuit is operable to generate a ...
在整个系统中,驱动或板级代码调用pinmux相关的API获取引脚后,会形成一个(pinctrl、使用引脚的设备、功能、引脚组)的映射关系,假设在某电路板上,将让spi0 设备使用pinctrl0的fspi0功能以及gspi0引脚组,让i2c0设备使用pinctrl0的fi2c0功能和gi2c0引脚组,我们将得到如下的映射关系: 502 { 503 {"map-spi0", sp...
* This code implements the DMA subsystem. It provides a HW-neutral interface * for other kernel code to use asynchronous memory copy capabilities, * if present, and allows different HW DMA drivers to register as providing * this capability.*...
They granted GateKeepers the right to vet code. They didnt say this was free. you seem very keen on "wiping out any profit Apple made". i'm guessing you dont want new products to be developed from profits made? you know that's how businesses work. you dont make profit, you ...

Do you have any reference code, or document that would be helpful for the DMA implementation with ADC.Thanks for your help! 0 Kudos Reply 11-05-2024 05:33 PM 502 Views Zhiming_Liu NXP TechSupport Hello, I don't find such reference code in doucument. Best Regards,Zhiming 0 ...
I'm not sure if i understand how your code works. in your example you used memory to memory. I dont know how the timer start transfer and not increment the source address. If timer interrupt and dma channel are not ready ? If timer interrup two times to dma stay ready ? The timer ...
Kind Code: T5 Abstract: In an embodiment, an apparatus and method include reordering direct cache access (DCA) and non-DCA transfers so that DCA transfers are last transactions and therefore closer to an interrupt than non-DCA transfers. Embodiments also include coordinating with interrupt processing...
