Flash Write Example

The Flash Write Example reads characters from UART, writes them to flash, and echos them.

The application first erases a page in flash. Next, it reads a character from the UART port. If a new character is detected, the character is written to flash and the flash address is incremented. The value is then read again from flash and output using UART. This output can be tracked in a COM listener (for example PUTTY).

The name of the example is flashwrite_pca10028. If you are not using the Keil Pack Installer, you can find the source code and project file of the example in the following folder: <InstallFolder>\Nordic\nrf51\examples\peripheral\flashwrite

Testing

Test the Flash Write Example application by performing the following steps:

1. Compile and program the application.
2. Start a COM listener like PUTTY and connect to the used COM port at 38400 baud rate.
3. Write a character and observe the echo.
