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 7: Implement SPI FeatureDiagnosing the Situation

4848

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.

12. At the top of the file, create a variable for stack index.

13. In the Write SPI code, use stack index to write data to sequential locations, incrementing stack index after each write.

14. In the SPI to LCD code, use stack index to retrieve last written data, then decrement stack index to previous location.

15. In the Read SPI code, use stack index to retrieve last written data.
