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
Hardware requirements
=====================
- Micro USB cable
- LPCXpresso55S69 board
- Personal Computer
- 4-pin flat cable
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.
