Device Info

All AVR devices can be used. This example has been tested with the following setup:

• Evaluation kits with a dataflash connecting through a SPI interface. To make this example work on STK600 define AT45DB041 in config file.

Description of the example

• Send "Read Status" command to the dataflash.
• Read back the status of the dataflash.
• If status "ok", both SPI_EXAMPLE_LED_PIN_EXAMPLE_1 and SPI_EXAMPLE_LED_PIN_EXAMPLE_2 are 'on' else SPI_EXAMPLE_LED_PIN_EXAMPLE_1 is 'on' and SPI_EXAMPLE_LED_PIN_EXAMPLE_2 is 'off'.

Compilation Info

This software was written for the GNU GCC and IAR for AVR. Other compilers may or may not work.
