Re: Fabrice/Euphoric experiments with soft serial through TT

Hello

Yes very good

But leaves very little time to do any thing else

38600 baud is 26.041uS bit time (transfer rate of 3.86k bytes/s, one start bit one stop bit and 8 data bits)

IMhz bus = 1us tick time, that gives you 26 ticks before you have to send or receive another bit

Re: Re tap2cd does not work

hello,

just found another version with 62k file size from oric sdk 1.4 bin folder (I would never have looked there, downloaded versions were 30k and 50k)

that version works on win 7

so there are 3 versions with file sizes 30k , 50k and 62k
