SPI = Serial Peripherial Interface it is a serial synchronous interface usually running at 100KHz 400KHz 1MHz or even 4MHz clock frequency transmiting one bit per one clock cycle.the delay is done to slow faster clock down to 100KHz
Solved: Hi All, We have one SPI device ( spi-device-1 )which needs reset HIGH before probe happen. To make it, we used pinctrl-assert-gpios = ; Now,
Good information.
Solved: Hello, I'm using a k02FN64VLH10. I want use the SPI to transfer 4 bytes to a analog converter. The ChipSelect signal must not be unasserted
Delay(75us); // How do I add this?? rxData = SPIWrite(RegisterAddress); SetChipSelectPin(1); Hopefully I explained my question. I am a little new to using the SPI bus. So my apologies if I am missing something easy. Thanks!
SPI DMA Transfer Delay PradeepCool Level 3 1 Jul 2024 Hi Team, We are working on transferring 4096 bytes to an External Soc through TRAVEO CYT2CL SPI with DMA.Since we need to transfer these many bytes quickly we opted for 2D Transfer. But, with 2D Transfer the interrupt is ...
The SPI works great, but the problem is that I need to delay the read by the master (AM335x). I do not see a way to introduce a delay before reading MISO on the McSPI. We can make the clock slower, but that reduces our chances of running at max acquisition rates. Wha...
