Re: [opendiag] 5bps initialization in VB

Hi

1.) you can set the 5 Baud without problem directly in USART of PC . ( put 23040 in DLH and DLL )

2.) a slow init pattern is always 8 bit , no parity , 1 stop

regards

Subject: [opendiag] 5bps initialization in VB

Ok' since 5bps is not a standard baud rate to set on any PC, I think
I must do the initialization by doing bit-bashing (software-made
serial stream) I tried pulsing DTR and RTS lines giving 200ms of
delay (1000ms/5bps = 200ms right?) and tried sending the 0x01(engine)
address using the 1 start, 7 data, odd parity 1 stop settings (that's
a 1-0000001-1-1 ?). Can't initiate the ECU. I hope it's not Vb's lame
slow interpreter wich can't set dtr or rts line on the correct
timing :(. I tried commlite to spy the port when Vag-com wakes up the
ECU but can't see any bytes not until the ECU sends the sync byte
(55) after the 5bps wakeup :P Help!

Any one did the init. in vb before?
