BL616 SPI CS by GPIO #186

Closed WGR7 closed 7 months ago

WGR7 commented 7 months ago

Hi,

I have a BL616 as a SPI Master.

I need to know if it's possible to control SPI Chip Select signal by bflb_gpio_set or bflb_gpio_reset. I've tried to reconfigure CS Pin after calling bflb_spi_init, but the cpu got freezed.

Can BL616 SPI Master control a slave by selecting cs signal with bflb_gpio_set/reset?

Regards.

All of our spi demo like lcd use software cs and use bflb_gpio_set/reset, you should check again your code by yourself.
