Happy Xmas all
I'm using the "on" instruction to parse the first 32 control characters of the ASCII code table = 0x00 to 0x31 :-
On DataIn goto TD,MS,MS,MS,MS,MS,MS,MS,OP,OP,OP,OP,OP,OP,Sft,DCG,WCG,WS,WClkM,LEDCl,HWC,L1,L2,L3,L4,Hm,CS,MS,MS,MS,MS,MS
Everything works fine, going to the right subroutine, down to L2 ( where L1 and L2 are code to set Line 1 and line 2 on a 20 x 4 OLED - using hex codes 0x15 and 0x16). However, if I then send the L3 and L4 codes, 0x17 and 18 the re-direction is only to L2.
I have tested the coding and 20 x 4 OLED addressing separately so there's no problem with the subroutine code of addressing the OLED - it overcomes the usual OED 1,3,2,4 line addressing to make life easier. The changes from the AXE133Y type command structure of 254, 192 etc are because I'm running over infra red which only runs on 7 bit data. Using the ASCII command codes makes obvious sense whilst maintaining AXE1xx compatibility for e.g. the display time code of 0x00 and the writable messages 1 to 7 - which are all parsed and display correctly.
Questions
1 Reading the forum there is reference to a coding line being "too long" but I can't find a definition of the maximum permitted length for a line of code. Anyone point me to that definition please ? I have just reduced all my labels to (mostly) 2 characters to reduce the line length to the above but still get the same result. PE 6.08.6 doesn't flag any errors.
2 Anyone know of any limitations in the "on" command ? Manual 2 says it can handle :-
Syntax:
ON offset GOTO address0,address1...addressN
- Offset is a variable/constant which specifies which Address# to use (0-N).
Where N is apparently infinite - but this is a simple 8 bit cpu so there must be a practical limit to N. Anyone know what Nmax is please ?
Any suggestions while avoiding the washing up most welcome
