To run OLED Boot Countdown Animation

- Build the code:
	- make clean
	- make

- On term1, run the command:
	- openocd -f interface/stlink-v2.cfg -f target/stm32f4x.cfg

- On term2, run the command:
	- arm-none-eabi-gdb --nx -ex 'set remotetimeout unlimited' -ex 'set confirm

off' -ex 'target remote 127.0.0.1:3333' -ex 'monitor reset halt' -ex 'monitor flash write_image erase <PATH_TO_BUILD_OUTPUT>/flash.bin 0x08000000' -ex 'monitor reset halt' <PATH_TO_BUILD_OUTPUT>/flash.elf

To run OpenOCD scripts:

- On term1, run the command:
	- openocd -f interface/stlink-v2.cfg -f target/stm32f4x.cfg

- On term2, run the command:
	- telnet localhost 4444
	- reset halt

	- Continue on term2. Enter each of the TCL commands & functions in the script manually.
