Overview
========
The dspi_interrupt example shows how to use DSPI driver in interrupt way:
In this example , one dspi instance used as DSPI master and another dspi instance used as DSPI slave in the same board.
This example does not use the transactional API in DSPI driver. It's a demonstration that how to use the interrupt in KSDK driver.
1. DSPI master send/received data to/from DSPI slave in interrupt . (DSPI Slave using interrupt to receive/send the data)
Toolchain supported
===================
- IAR embedded Workbench 7.50.1
- Keil MDK 5.17
- GCC ARM Embedded 2015-4.9-q3
- Kinetis Development Studio IDE 3.0.0
- Atollic TrueSTUDIO 5.4.0
Hardware requirements
=====================
- Mini/micro USB cable
- FRDM-K22F board
- Personal Computer
Board settings
==============
SPI one board:
Transfer data from instance0 to instance 1 of SPI interface.
SPI0 pins are connected with SPI1 pins of board
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
INSTANCE0(SPI0) CONNECTS TO INSTANCE1(SPI1)
Pin Name Board Location Pin Name Board Location
MISO J1 pin 11 MISO J2 pin 8
MOSI J1 pin 16 MOSI J2 pin 10
SCK J1 pin 15 SCK J2 pin 12
PCS0 J24 pin 9 PCS0 J2 pin 6
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Prepare the Demo
================
1. Connect a mini USB cable between the PC host and the OpenSDA USB port on the board.
2. Open a serial terminal on PC for OpenSDA serial device with these settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
3. Download the program to the target board.
4. Reset the SoC and run the project.
Running the demo
================
When the demo runs successfully, the log would be seen on the OpenSDA terminal like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
dspi_functional_interrupt example start.
This example use one dspi instance as master and another as slave on one board.
Master and slave are both use interrupt way.
Please make sure you make the correct line connection. Basically, the connection is:
DSPI_master -- DSPI_slave
CLK -- CLK
PCS -- PCS
SOUT -- SIN
SIN -- SOUT
DSPI transfer all data matched!
