Sorry,

when I am changing Disk/Album the disk name/number and track name/number change and the time changes. Which order should I send the new information to the HU? Also when do I need to send the seek and play commands to the HU?

When the Track changes only the track name/number changes to do I still need to send a seek command? do I need to send the play command aswell?

When the seconds count up do I only need to send the new minutes and seconds or do I need to send the play command aswell?

Can I just run through the order that I need to send comamnds to the HU when diffrent things happen.

DISK CHANGE

seek
d xx..xxx 0
t xx..xx 0
Cdt
cms
play

TRACK CHANGE

t xx..xx 0
Cdt
cms
play

TIME
cms

Is that right?

I'm getting there now. The HU is talking to the PC and visa versa.

Is there any way to reduce the amount to time the "M1 DISC XX" stays on screen when you change disks/Albums?

Also if you change Disk title/Song Title in the middle of playing a track, does the HU update the screen?

Cheers

forget it. I figured it out by moving to v5.

Also to anyone else interested the 1->6 key can be accessed by adding

case 0xC0:
   switch (Message[8])
   {                     
      case 0x10:
         UART_SendByte ('1');   // F1
         break;
      case 0x20:
         UART_SendByte ('2');   // F2
         break;

       etc


   }
break;


to the //*** Key command from Head Unit section

Hi,

When I use the hex fire that comes with IPBus v4.0 the emulator gives a nice output:

SnBPBNBpBnBPBFB

however, if I run a simple make on the code and use the new hex file I get.

SCD 10 10 06 00 34 02 40 02

How do I get rid of all this extra data?

PS ..can I get the emulator to send a diffrent char if one of the six number keys is pressed? i.e the ones you would use to select a CD (1->6)  on the MD

Doh!, Had the wrong WinAvr version installed. Now compiling fine.

The problem I have now is that after installing IPbus_v5_MD the HU show the device as External (which is fine) but just sits there flashing TOC READ at me.
I really want to use some of the features of this version such as:

FUNC -> enter to functions mode and choises function
UP or DOWN => fastforward on tracks with 1 track step, this function allows at fast browsing on tracks to see their names (only in MD mode)
etc..

I am using the emulator to control a PC if this makes any diffrence.

Also what is "Stupid mode"?

Cheers

Hi,

When I tyr to compile the source I get the following error

It cannot find avr/timer.h! and I  cannot find it under C:\WinAVR\avr\include\avr

Please help!!!

Do you know the case codes for the 1-to-6 quick access codes?
Also
If case 0x30 is Key command from Head Unit na d case 0x50 is Head Unit Ask for CD Text what is case 0x40?

i.e

case 0x??:
   UART_SendByte ('1');   // Quick key 1
   break;

Cheers
   Chris

so thats

Cheers, I'll give that a try when I get to work on monday. Failling that i'll have to risk it on my new HU.

Well I've finally got round to putting all the bits together and hooked the HU and emulator up to a PC and everything seems to be great!
The PC is resciving S,s,P,pN,n etc and I can update the DISK/TRACK and Min/Sec via the C and c commands, the only problem is that I cannot get the HU to display text sent via the dxxxxxxxxxxxxxxxxxxx command. I know the HU has recived the data because I altered the code to send a # after it recives th 19th char but when I press Display on the HU the read out is blank. I have tryed sending the text in both ascii and hex with no succsess. The HU I am testing it on is quite old (KEH-P4530R), does it need a particular function (such as CD-TEXT) to display the data? I know it displayed the 7 Char Disk name I configured when it was connected to the cd-changer.

Am I missing something obvous? any suggestions would be great!


Cheers

Cheers!

Does this mean that ASENBUS goes low when you select radio etc?
if not, does the HU send a stop signal to the CDMC?

Hi,

I was wondering if anybody can explane when and how ASENBUS becomes active and what its perpose is?

From looking at the code it seams to be active low! but I think I must be mistaken. Does it go high the moment the HU is switched on or only when the CDMC is selected.

Cheers
