34 Please spend the next 5 minutes trying to find the I2C LCD bug. SH7216 Motor LEDs LCD E²E² EEPROM Beagle Beagle Header Power Micro SD E10A Debugger Circuitry USB Port Mini USB USB Port Reset I2C

35 Using the Beagle I2C analyzer, we can quickly diagnose this problem. When we Write to I2C, the Data Center displays this transaction. The first byte of data is 00. Remember that 00 is our offset. When we click I2C LCD, the Data Center displays these transactions. If we closely examine the data we see that the write transaction says 08. This means that the data is being pushed to the LCD starting at offset 08. The correct offset is 00 as shown in the first write transaction. Section 5: Bug 1 – I2C LCD Solution

Go back to the Application Box 6. Click Read SPI 7. Click Write SPI and type “ABCDEFGHIJKLMNOP” 8. Click Read SPI 9. Go back to the Data Center Software and compare the data. 10. Click SPI LCD Section 7: Implement SPI Feature Diagnosing the Situation

48 Modify the source code so that a data stack is created. When Write SPI is clicked, you must be able to write data by SPI multiple times in sequence to the SD Card. When SPI LCD is clicked, you must be able to send data by SPI from the SD Card to the LCD in the reverse sequence. When Read SPI is clicked, you must only be able to read the last data written to the SD Card. Section 7: Implement SPI Feature The Task
