I tested AXE 033 LCD with Picaxe 14M standard 4 MHZ frequency.
In that 4MhZ all works fine.
When setting up 14M to 8MHZ mode LCD seems not working properly it shows messy signs.
I'll have also tested by changing pause value 10 to pause 20 after changing frequency to 8Mhz.
So doesn't AXE033 works...
