SPI MEMORY CHIP INTERFACING WITH NRF51

[VIJAY]

Hi, I am interfacing external memory chip that is based on SPI protocol with nrf51822. I have to read more than 255 byte via spi in single buffer with 4 byte of command. Even also i wanna write more 255 byte send on memory chip.But in SDK, spi buffer size is 256 byte. So how i can send and receive more than 256 byte at a time. Please help me.I am new to nordic.Is there any api to get single byte transfer/response?so i can  deal with by byte to byte.

Hi,

The SPIM driver on the nRF51 doesn't use EASYDMA, which means that the maximum size one can send "at once" is limited by the size of the double buffered one byte TXD register. 

Best regards
