ESP32S3 SPI2 and SPI3
Posted: Sun May 05, 2024 12:00 pm
Hi,
I am desinging a PCB with ESP32-S3FH4R2 which uses Quad SPIs (SPI0/SPI1) for in-package memory.
I would like to route SPI2 and SPI3 to other devices on the board and would like to utilize the maximum available performance.
Therefore for SPI2 I have chosen the IOMUX and routed the pins as follows:
For SPI3 GPIO_MUX is the only available option Should I prefer the FSPI capable pins to get maximum speed?? and use pins 33 - 38
Or is it OK to use any GPIO to achieve the same performance on SPI3?
Regards
