1. Modify the C function in Example 7.1 to configure SPI2 so that SPI2 operates with the following parameters:
• Use PB15, PB14, and PB10 pins for MOSI, MISO, and SCK signals.
• Select master mode and disable all interrupts.
• SCK idle high and shift data on the falling edge.
• Shift data LSB first.
• Data frame is either 8-bit or 16-bit (using the incoming parameter ds to specify, when ds = 0, data size is 8-bit; otherwise, data is 16-bit)
• Set data baud rate to 1.25 MHz assuming that the peripheral bus clock is 80 MHz.
• Enable TX DMA and RX DMA.
• Disable CRC checking.

3. For the circuit attached in Figure 7.26, write a C program to display the following patterns forever with each pattern lasting for 800 ms assuming that the STM32L475 is running at 80 MHz:
12345678
23456789
34567890
45678901
56789012
67890123
78901234
89012345
90123456
01234567
