WebTo ensure the proper operation of the SD card, the SD CLK signal should have a frequency in the range of 100 to 400 kHz. To communicate with the SD card, your program has to place the SD card into the SPI mode. To do this, set the MOSI and CS lines to logic value 1 and toggle SD CLK for at least 74 cycles. After the 74 cycles (or WebOct 25, 2015 · To send, hold the chip select low, and clock out bits on MOSI at the desired rate. To receive, handle chip select going low by sampling bits off MISO on the desired edge on the clock line. Stick everything in a buffer and process the buffer when the chip select line goes back high.
