This demo describes the usage of Quad Decoder feature in FTM module, which can be used to count the position of decoder.An external decoder is used to generate the PHA and PHB's signal. These two signals are feed to the FTM pins with Quad Decoder feature (FTMx_QD_PHA and FTMx_QD_PHB). Then, the counter value and direction would be displayed in terminal window predically. You can open the mex file with MCUXpresso Config Tool to do further configuration of pin, clock and peripheral.

The i2c_interrupt_b2b_transfer_master example shows how to use i2c driver as master to do board to board transfer with interrupt:In this example, one i2c instance as master and another i2c instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

The i2c_polling_b2b_transfer_master example shows how to use i2c driver as master to do board to board transfer using polling method:In this example, one i2c instance as master and another i2c instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

The fee_bple example shows how to use MCG driver to change from FEE mode to BLPE mode: 1. How to use the mode functions for MCG mode switch. 2. How to use the frequency functions to get current MCG frequency. 3. Work flow Boot to Fee mode from default reset mode Change from FEE -> FBE -> BLPE Change back BLPE -> FBE -> FEE Get System clock in FEE mode to blink LEDIn this example, because the debug console's clock frequency may change,so the example running information is not output from debug console. Here theLED blinks to show that the example finished successfully.

The pee_bpli example shows how to use MCG driver to change from PEE mode to BLPI mode: 1. How to use the mode functions for MCG mode switch. 2. How to use the frequency functions to get current MCG frequency. 3. Work flow Boot to PEE mode from default reset mode Change mode PEE -> PBE ->FBE -> FBI -> BLPI Change back BLPI -> FBI -> FBE -> PBE -> PEE Get System clock in PEE mode to blink LEDIn this example, because the debug console's clock frequency may change,so the example running information is not output from debug console. Here theLED blinks to show that the example finished successfully.

The pdb_dac_trigger example shows how to use the PDB to generate a DAC trigger.Based on the basic counter, to use the DAC trigger, just to enable the DAC trigger's "milestone" and set the user-defined value for it.The DAC's "milestone" is called as "interval". Multiple DAC trigger intervals can be included into one PDB counter's cycle.DAC trigger's counter would reset after the trigger is created and start counting again to the interval value.In this example, the DAC is configured with hardware buffer enabled in normal work mode. Once it gets the trigger from the PDB, the buffer read pointer increases.

The PIT project is a simple demonstration program of the SDK PIT driver. It sets up the PIThardware block to trigger a periodic interrupt after every 1 second. When the PIT interrupt is triggereda message a printed on the UART terminal and an LED is toggled on the board.

The uart_functioncal_interrupt example shows how to use uart driver functionalAPI to receive data with interrupt method:In this example, one uart instance connect to PC through uart, the board willsend back all characters that PC send to the board.
