I used the nRF52832 SDK15.0 S132,the question is:
(1) I used SPI_0_Instance for APP_SDCard and SPI_1_Instance for other device;
The Setting of SPI_1_Instance frequency is 8MHz, I can only set the SPI_0_Instance(APP_SDCard) frequency for 500KHz! If I increase the frequency of SPI_0_Instance,the write function of APP_SDCard is not work,it will be crashed! But the frequency 500KHz is too low for me !
I try to reduce the frequency of SP1 to 1MHz, it's not work for SP0!
Who can help me ,thanks!
