- MK40DX256VMD10 MCU (100 MHz ARM® Cortex® -M4 core, 512 KB flash, SLCD, USB FS OTG, 144 MAPBGA)
- Integrated open source JTAG (OSJTAG) circuit
- MMA8451Q 3-axis accelerometer
- Four user-controlled status LEDs
- Four capacitive touchpads and two mechanical pushbuttons
- General-purpose TWRPI socket (Tower plug-in module)
- Potentiometer, SD card socket and coin-cell battery holder
Step-by-Step
Installation Instructions
In this Quick Start Guide, you will learn how to set up the TWR-K40D100M
module and run the default demonstration.
-
Install the Software and Tools
Install the P&E Micro
Kinetis Tower toolkit. The toolkit includes the OSJTAG and USB-to-serial drivers.
These can be found online at freescale.com/TWR-K40D100M. -
Configure the Hardware
Install the included battery into the VBAT (RTC) battery holder. Then, plug the included segment LDC TWRPI-SLCD into the TWRPI socket. Finally, connect one end of the USB cable to the PC and the other end to the power/OSJTAG mini-B connector on the TWR-K40D100M module. Allow the PC to automatically configure the USB drivers if needed. -
Tilt the Board
Tilt the board side to side to see the LEDs on D8, D9, D10 and D11 light up as it is tilted. -
Navigate the Segment LDC
The segment LDC will display the seconds elapsed since boot-up. Press SW2 to toggle between viewing the seconds, hours and minutes, potentiometer and temperature. -
