One of the many benefits of the Promira™ Serial Platform with SPI Active Level 1-3 Applications is that it gives you several options to program SPI devices – you can use the Control Center Serial, Flash Center, or the Promira API software tools (each supported on various platforms). Following is an overview of programming an SPI EEPROM by executing command line code with the Control Center Serial Software Command Line Mode. For details, please refer to our knowledge base article, Programming an SPI EEPROM Using Promira Serial Platform and Control Center Serial Command Line on Linux.

In this example, the Promira platform writes and reads multiple bytes from the Atmel SPI EEPROM AT25080A (which is on the I2C/SPI Activity Board). The Promira platform is the SPI master, and the AT25080A on the I2C/SPI Activity Board is the SPI slave.

• The Promira platform is connected to the AT25080A on the I2C/SPI Activity Board using the 34-10 I2C/SPI cable.
• The Promira platform is configured for Ethernet over USB interface (see Figure 3 below), and provides 3.3V SPI signals and 5V VDD signal to the I2C/SPI Activity Board.
• The Control Center Serial Software is connected to the Promira platform.
• The Control Center Serial Software is setup in command line mode. For details, please refer to the section Command Line Option in the Control Center Serial Software User Manual.

1. Open a terminal on the computer.
2. From the file controlctr (which is located in the Control Center Serial package folder), enter the following:

   1. Controlctr -c
   2. connect xxxx-xxxxxx

      (xxxx-xxxxxx represents the serial number of your Promira platform)

   3. batch ./examples/spi-eeprom-read.xml
   4. disconnect xxxx-xxxxxx

      (xxxx-xxxxxx represents the serial number of your Promira platform)

   5. quit
   6. The results are shown in Figure 4 below.
