ctimer_match_interrupt_example#
Overview#
The Simple Match Interrupt project is to demonstrate usage of the SDK CTimer driver with interrupt callback functions In this example the upon match and IO pin connected to the LED is toggled and the timer is reset, so it would generate a square wave. When the number of times of entering the interrupt callback function is greater than matchUpdateCount, matchValue will be divided by 2, and matchUpdateCount will be multiplied by 2. When matchUpdateCount == 0XFF, matchUpdateCount and matchValue will return to the original settings. With an interrupt callback the match value is changed frequently in such a way that the frequency of the output square wave is increased gradually.

Build the demo to generate a bin file. Note: If need to generate bin file using MCUXpresso IDE, below steps need to be followed: Set in example Properties->C/C++ Build->Settings->Build steps->Post-build steps->Edit enbable arm-none-eabi-objcopy -v -O binary “&{BuildArtifactFileName}” “&{BuildArtifactFileBaseName}.bin”
This plainload example linked the vector table to 0x00000000, but program to external flash 0x10000000.
Program the bin file to external on board flash via SEGGER J-FLASH Lite(V6.22 or higher):
a. Open SEGGER J-FLASH Lite, select device LPC54S018.
b. Click the ‘Erase Chip’ to erase the extrenal flash.(if can not success, press SW4 button and reset the board, and try to erase again)
c. Select the bin data file, set the ‘.bin/Erase Start’ address to 0x10000000, then click ‘Program Device’ Note: Please use above way to program the binary file built by armgcc tool chain to external flash. For IAR, KEIL, MCUXpresso IDE, you can use the IDE tool to program the external flash.
