+==== Update 2021: timing problems ====
+I started having weird timing problems when programming the chip, I had to make the following change to Makefile:
+<code>
+-pro8: CFLAGS += '-DMAX_TIME_COUNT=F_CPU>>2' '-DNUM_LED_FLASHES=4' '-DWATCHDOG_MODS'
++pro8: CFLAGS += '-DMAX_TIME_COUNT=F_CPU>>4' '-DNUM_LED_FLASHES=1' '-DWATCHDOG_MODS'
+</code>
+Then compile with <code>make clean; make pro8</code>
