Documentation to external flash memory to nrf51822?

Is there any clear documentation to add an external memory to the nrf51822 to store some sensor data. How is the performance and stability when interfaced this way?

  • No there's no specific documentation for adding external memory because it depends on what kind of memory you want to add. There's no direct connection to the microcontroller bus, so you'll need to add an external chip and talk to it over SPI or I2C or UART or whatever protocol your external memory chip uses, just like any other peripheral. And stability and performance will be exactly the same as using SPI or I2C or UART to talk to any other kind of peripheral.
