1.1.47 with experimental features

[Sambas]

Available here http://kotisivu.dnainternet.net/sakrkorh/vems/firmware_1.1.47_ext_v2.zip

All precautions apply same also here as does with previous releases.
Start from changelog

included features:
* Speedsensor (!PS2KEYBOARD)
* N2O retard (N2O_RETARD)
* Warning feature (WARNING_BEEP)
* Advanced misc_outputs (EXPENSIVE_MISC1OUT & EXPENSIVE_MISC2OUT)

known bugs:
* megaloader has problems with downloading config, terminal works ok (Manmcdbye)
* Megatune 3d map view sometimes buggers, 2d ok

!note even with some previous releases in megatune menus show advanced features, firmware might not actually support it. my_make tells you which features are enabled.

edit: ext package replaced with v2, speedsensor and megatune problems hopefully fixed

Sambas, great work as usual - what is the problem with Megaloader?  I can take a look at it if we need to - the problem is that the download is too passive, we could really do with sending a payload size in the first instance so that MegaLoader knows when to close, rather than relying on a timeout.

Thank you!
Is the non-geek LCD mode also enabled (LCD page 4)?
And is SDcard logging enabled in firmware (so could be used with VEMS Tune)?

[Sambas]

Yes both are available by default. Non-geek lcd is my_make CUSTOMLCD variable.

Brilliant.  I just need a car to use this on now!

i know that feeling dnb

I have same same trooble

Or i have the car, i just dont have the time to try it

Is LCD still slowish with this firmware?

[MWfire]

If you want use speed sensor, than KNOCK_ALTERNATIVE must be enabled. Whiout KNOCK_ALTERNATIVE
 speedsnesor works, but you can't see speed or gear in megatune.

Any of you know were it can be seen how to make the hardware connection for the speed input, meaning, were do i mount the wire internally at the genboard?



Thanks,
Skassa

You have to use PS2 keyboard DATA input pin. Be careful though, this input is unprotected and connect directly to Atmega128. Beware of voltages over 5volts, it could (and most likely will) kill CPU.

I wonder if we could use some diodes or something to protect the input better?

[rob@vems.co.uk]

Definately use a zener diode to protect the DATA line.

http://www.vems.hu/files/Marteleur%20Tim/PS2header.JPG (up pin is 1., down 4.)

or if you use ps cable, black is GND(1. pin on vems), yellow is clock(4.pin on vems)

d27 is 5.1V zener diode.

If you want use speed sensor, than KNOCK_ALTERNATIVE must be enabled. Whiout KNOCK_ALTERNATIVE
 speedsnesor works, but you can't see speed or gear in megatune.

Updated pack with hopefully fixed vemsv3.ini, if this case was speed and gear missing from logs?

I think that firmware must be complied whit knock_alternative fuction. Like this mymake(12x12)
http://www.vems.hu/files/DamirMuha/1.1.47/my_make1147.txt
I tried change settings.ini(set knock_alternative), but than i can't start megatune
Can you compile this my_make?
