Overview
========
The TPM project is a demonstration program of the SDK TPM driver's output compare feature.
It sets up one TPM channel to toggle the output when a match occurs with the channel value. The user
should probe the TPM output with a oscilloscope to see the signal toggling.
Toolchain supported
===================
- Keil MDK 5.24a
- IAR embedded Workbench 8.22.2
- GCC ARM Embedded 7-2017-q4-major
- MCUXpresso10.2.0
Hardware requirements
=====================
- Mini USB cable
- MAPS-KS22F256 board & MAPS-DOCK board
- Personal Computer
Board settings
==============
The tpm example is configured to use UART1 with PTE0 and PTE1 pins. To make JLink serial
device work, the jumpers on MAPS-DOCK board should be set as following:
- JP5: UART1 part jumpers connected
To observe the example result, please connect Pin-53 to Pin-56 on MAPS-KS22F256 board to see LED brightness change.
Prepare the Demo
================
1. Connect a mini USB cable between the PC host and the USB port (CN14) on MAPS-DOCK board.
2. Open a serial terminal on PC for JLink 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. 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, please connect Pin-53 to Pin-56 on MAPS-KS22F256 board to see LED brightness change.
You can see information from the terminal as below.
