3.5 EXERCISE 5: USING THE SPI DRIVER
The purpose of this exercise is to use the SPI driver to program the embedded SPI EEPROM.
The structure of the main module and the batch file for efficient HIWARE C language com-
piling as well as the ST72334 resource directory are located in the SPI directory.
First, open the “SPI.wsp” project file.
The resource files are displayed as shown in
Figure 13. SPI Resource Files
Table “tab[16]” contains the configuration for the 7-segment LED displays. When addressing
tab[i], the corresponding digit i is accessed when PDDR is pushed.
Label “lab1” is an infinite loop. It starts a new conversion, waits until it is completed, and
store the tens and ones unit value into the i and j registers. Then, it outputs the i and j values
on Port D, and decreases a counter so that the result is displayed on the LEDs. Then, it
starts again.
A high level on output PA3 (output PA2, respectively) selects the tens (ones, respectively)
value on the dedicated 7-segment LED display.
