Software can enable one or two external oscillators if desired. The external oscillator for the Multipurpose Clock Generator (MCG) module can range from 32.768 kHz up to a 32 MHz crystal or ceramic resonator. The external oscillator for the Real Time Clock (RTC) module accepts a 32.768 kHz crystal. Figure 5. External clock source circuitry The clocking circuitry on the KwikStik is shown on sheet 7 of the schematics and in Figure 5. A 4.0 MHz ceramic resonator with built-in load capacitors is the default external source for the MCG oscillator inputs (XTAL/EXTAL_MAIN). A 32.768 KHz crystal is connected to the RTC oscillator inputs by default. 2.3 System Power The main power source for the KwikStik comes from either one of the two Micro USB ports. When plugged in, power for the system is derived from a Freescale MC34727CFCR2 3.3V regulator. When installed into a Tower System, the KwikStik can be powered from either an on-board source or from another source in the assembled Tower System. Switching the ON/OFF switch to the OFF position will cut power supply to the K40X256 MCU. The JM128 will remain powered even if the switch is in the OFF position, enabling the KwikStik for external programming. Refer to section 2.4, “Debug Interface” for information on how to use the on board SEGGER J-link debug interface. Refer to Figure 6 for location and correct usage of the ON/OFF switch. KWIKSTIKK40UM KwikStik-K40 User's Manual Page 8 of 19 Figure 6. KwikStik ON/OFF switch positioning. An MgLi rechargeable battery is available to test low power capabilities of the K40X256. This battery is recharged whenever USB power is available. 2.4 Debug Interface An MCF51JM128VLD based SEGGER J-Link circuit provides a JTAG and Serial Wire Debug (SWD) interface to program the on-board K40X256 MCU or an external Kinetis MCU. 2.4.1 Programming an on-board MCU A JTAG debug interface from the JM128 to the K40X256 allows programming through a USB connection. A standard USB A male to Micro-B male cable (provided) can be used for debugging via the USB connector, J18. Drivers for the J-Link interface are provided on the KwikStik DVD and are also available from SEGGER here: http://www.segger.com/cms/jlink-software.html. Note: The ON/OFF switch, SW1, needs to be in the ON position in order to provide power to the K40X256. A green led, D4, will indicate when the switch is turned to ON. 2.4.2 Programming an external Kinetis MCU The Cortex Debug connector is a 10-pin (0.05") connector providing access to the SWD, SWV, JTAG, cJTAG, and EzPort signals available on the K40 device. The pinout and K40 pin connections to the debug connector, J8, is shown in Table 1. Note: The ON/OFF switch, SW1, needs to be in the OFF position in order to provide ground to the Cortex Debug connector. Table 1.

In order to target an off-board Kinetis device the user will need to solder on a connector and use a ribbon cable to connect to the external device. J8 can be populated with a 10-position (2x5), .05” pitch surface-mount header such as the Samtec FTSH-105-01-F-DV or compatible. Possible ribbon cables include the Samtec FFSD-05-D-06.00-01-N (6”) or FFSD-05-D-12.0001-N (12”). The ON/OFF switch of the KwikStik will need to be in the OFF position to turn off the onboard K40X256 and to provide ground to the cortex debug connector. 2.5 Infrared Port An infrared transmit and receive interface is implemented as shown in Figure 7 below. The IR_TX pin drives an infrared diode by switching Q4. The receiver uses an infrared phototransistor connected to an on-chip analog comparator through an optional low-pass filter. Internal to the K40 device, the output of the analog comparator can be routed to a UART module for easier processing of the incoming data stream. Figure 7. Infrared Port Implementation 2.6 General Purpose Tower Plug-in (TWRPI) Socket The KwikStik features a socket that can accept a variety of different Tower Plug-in modules featuring sensors, RF transceivers, and more. The General Purpose TWRPI socket provides access to I2C, SPI, IRQs, GPIOs, timers, analog conversion signals, TWRPI ID signals, reset, and voltage supplies. The pinout for the TWRPI Socket is defined in Table 2. KWIKSTIKK40UM KwikStik-K40 User's Manual Page 10 of 19 Refer to Table 4 “I/O Connectors and Pin Usage Table” for the specific K40 pin connections to the General Purpose TWRPI socket. Table 2.

There are six individual electrodes on-board the KwikStik that simulate buttons. Touch Sensing Software (TSS) can be implemented for all of the electrodes. Additionally, two of these signals (E1 and E2) can use the TSI module. The touch sensing input (TSI) module of the Kinetis MCUs provides capacitive touch sensing detection with high sensitivity and enhanced robustness. Each TSI pin implements the capacitive measurement of an electrode. In order to use TSI on E1 and E2, the pull-up resistors R107 and R108 must be removed (they are not populated by default). The Xtrinsic Touch Sensing Software (TSS) transforms Freescale MCUs into touch sensors, giving designers the flexibility to select from more than 650 Freescale MCUs to add cost-effective touch sensing functionality to their human-machine interface (HMI) designs. Refer to Table 4 “I/O Connectors and Pin Usage Table” for the TSI and TSS signal connection details. KWIKSTIKK40UM KwikStik-K40 User's Manual Page 11 of 19 2.8 Segment LCD An LCD Display containing 306 segments is mounted on the front side of the KwikStik. The segments are driven by 39 front-plane and 8 back-plane signals from the K40X256 MCU (LCD_P1 – LCD_P47). The front-plane and back-plane signals are mapped according to Figure 8 and Figure 9. Figure 8. LCD Back-plane signals Figure 9. LCD Front-plane signals 2.9 Audio Input The KwikStik features audio input capabilities through an on-board electric omnidirectional microphone that can be sampled using the K40 ADC module. Figure 10.

Two separate circuits allow current consumption measurement of the entire system or of the K40X256 MCU. Both circuits include an Amp Meter and a Volt Meter. For the Volt Meter, test points allow measurement of voltage consumption of a 1 ohm precision resistor, from which the current consumption can be calculated. Usage of the Amp Meter requires the removal of the 0 ohm resistor in order to directly measure current consumption on the corresponding test points. Refer to Figure 13 for location of testpoints and resistors of the power consumption measuring circuit. KWIKSTIKK40UM KwikStik-K40 User's Manual Page 14 of 19 Figure 13. Power Consumption Measuring Circuit Note: R62 and R64 are populated with 0 Ohm resistors by default. In order to use the volt meter, they will need to be replaced by 1 Ohm resistors. 3 Input/Output Connectors and Pin Usage Table The following table provides details on which K40X256 pins are using to communicate with the the I/O interfaces onboard the KwikStik.
