Hello,
I am having a few issues with getting the SD card FATFS example code to share the same bus as another slave I transfer data to.
I have a few questions:
1) Since, I don't need the two slaves to transfer simultaneously, should I have them use the same SPI instance?
2) What part of the FATFS example needs to be done only once? I want to write to the SD card every 1 second or so, so I split the example code into two functions: sd_spi_start() containing the initializing and the mounting, and sd_write() containing the directory reading, file opening, file writing and file closing. So I was planning on calling sd_spi_start() once and the sd_write() multiple times... is this the correct approach?
3) Right now I am stuck where I write to SD card using sd_write() (Channel 6), write to the other slave using nrf_drv_spi_transfer() , then try to write to SD card again and it just gets stuck (the CS pin just stays low):
Do you have any idea to why this is happening?
