Hi,
I am using the RSPI driver on a rza1m CPU on a custom board. I want to get multiple register value from ADE. The speed is very important since I need to refresh all value every 100ms. I have difficulties to reach that limit because I have fond out that the chip select signal is staying low a long time after the last CLOCK toggle. I am using IOCTL in C language and the value of delay_usecs in the spi_ioc_transfer struct.
Yellow->CLOCK
GREEN->MOSI
BLUE->MISO
RED->CS
Do anyone know how I could reduce the delay for the chip select?
