Overview
The GPIO Example project is a demonstration program that uses the KSDK software to manipulate the general-purpose outputs. The example is supported by the set, clear, and toggle write-only registers for each port output data register. The example take turns to shine the LED.
SDK version
- Version: 2.15.000
Toolchain supported
- IAR embedded Workbench 9.40.1
- Keil MDK 5.38.1
- GCC ARM Embedded 12.2
- MCUXpresso 11.8.0
Hardware requirements
- Mini/micro USB cable
- EVKB-IMXRT1050 board
- Personal Computer
Board settings
No special settings are required.
Prepare the Demo
- Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
- Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
- Download the program to the target board.
- Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Note:
- this demo can only work properly on A1 silicon (MIMXRT105xxxxxB).
Running the demo
These instructions are displayed/shown on the terminal window:
