Hi everyone,
I am testing the SPI performance of RM42L432.
Complier: IAR.
SPI mode: normal SPI (Not MibSPI).
The detail code is attached below.
As the figure shown below, we found the minimum TX interval of SPI is about 2us. Is it the limitation of the MCU? How can we shorten the TX interval of SPI?
Will the MibSPI be better?
Channel 4: SPI_CLK
Channel 1: SPI_SIMO
Channel 3: SPI_CS
