Overview
|
|
========
|
|
The example shows how to use SPI driver with Azure RTOS. In this example,
|
|
one SPI instance used as master and another SPI instance used as slave.
|
|
|
|
Before running the example, need to connect the master SPI to the slave SPI
|
|
by a cable.
|
|
|
|
|
|
Toolchain supported
|
|
===================
|
|
- IAR embedded Workbench 9.20.2
|
|
- Keil MDK 5.36
|
|
- GCC ARM Embedded 10.3.1
|
|
- MCUXpresso 11.5.0
|
|

|
Board settings
|
|
==============
|
|
Connect SPI7 pins to SPI2 pins:
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
Master(SPI7) Slave(SPI2)
|
|
Pin Name Board Location Pin Name Board Location
|
|
MISO P17 pin 12 MISO P18 pin 6
|
|
MOSI P17 pin 10 MOSI P18 pin 10
|
|
SCK P17 pin 14 SCK P18 pin 8
|
|
SSEL1 P17 pin 1 SSEL0 P17 pin 16
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|

|
|
Prepare the Demo
|
|
================
|
|
Note: MCUXpresso IDE project default debug console is semihost
|
|
1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (P6) on the board
|
|
2. Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):
|
|
- 115200 baud rate
|
|
- 8 data bits
|
|
- No parity
|
|
- One stop bit
|
|
- No flow control
|
|
3. Download the program to the target board.
|
|
4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
|
|
|
|
Running the demo
|
|
================
|
|
|
|
When the example runs successfully, the console will output as below.
