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,
When using 32 bit data width for ExternalBuffer in SPI Channel configuration I've noticed that there is still a 6us delay between 4 bytes frames on SPI (see attachment). Interesting thing is that delay length is the same as frame length (6,23 us). I am using Spi_SyncTransmit API. Ho...
Re: SPI Read Register Delay Quote PostbyESP_Sprite»Thu Mar 02, 2017 1:34 am Hmm, the ESP32 may also have the hardware to do something like this... lemme check; I have a driver update in the queue anyway, may as well enable this when the hardware can do it. ...

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 ...
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 configured as descriptor complete. Our expectation is to get the interrupt after...
