Yes, it's packed BCD, which is also used in devices, like RTC's e.t.c.
And this is, what this thread is all about.

Back on topic, please. (aka: ... End Asm ...) BCD has as caped value, when compared to Hex, because the representation of A to F (10 to 15 decimal) isn't ever used in a Nibble (value = 0 to 9 dec). A Nibble is a half-Byte, which means it consists of 4 bits ( hi and low = UByte). In order to avoid t...

Hi Mike,

Have you tried with another browser, e.g. FireFox ?
If the automatic dl fails, click the link to manually start dl.

Even a 8086 can cope with that.

Probably the -Ofast (GCC optimizer setting).
Recomendations are: for 'production code' -O2 (no more is considered safe!)
(as stated on GCC's site)

Nice explanation but ... don't know how many here, are understanding ASM ?!?
(suppose probably less than 10% of all members)

Since certain devices require it, to use BCD formatted UBytes, this two #Define(s) might come in handy, to solve communication problems, with such devices. #Define setBCD(v) converts from: base 16 to: base 10 (v = Decimal/Hex) #Define getBCD(v) converts from: base 10 to: base 16 (v =...

So my problem is not converting 20 to hex, but putting 20 hex to represent 20 decimal. OK, now I hopefully understand, what you seemingly need. Try the below code: ' toBCD_Mac.bas -- (c) 2020-07-02, MrSwiss ' ' compile: -s console ' #Define toBCD(v) ( CUByte( (v) \ 10 Shl 4 + (v) Mod 10 ) ) Dim As ...

@Dinosaur, seems to me, that you've misunderstood what's written in the Docs, of the device. The encoding isn't, as you assumed in HEX, but in BCD (binary coded decimal). 5.2 Real Time Clock Registers [00h to 06h] These RTC (Realtimeclock) registers are stored as binary-coded decimal BCD format.

Which clashes with other header definitions (the Windows headers, no less). Nope, nothing to do with headers (the TRUE/FALSE issue) it is FBC related. It's a change in FBC itself: OK, up to and including version: 1.03.0 From version: 1.04.0 (introduction of Boolean type into FBC) it must be removed...

I'd suggest to use FBC 64 bit, whenever you are on a 64 bit operating system. The advantage is: the 32 bit emulator (WoW on WIN) isn't needed, at all. Typically: consumes more RAM and possibly, slows down execution speed. From my point of view, the 32 bit version, is only good for legacy 32 bit OS's...
