Topic: Inside the Profiler
Author	Post
Pascal 6 posts Popping In	12-04-2008 19:45 Good morning, Following are a few extensions that can be made to the Profiler. They are from my personnal investigations, use them at your own risk. I will update that topic each time I will discover some new interesting features not used in the "standard" Profiler. ------------------------------------- A 12 button keybord can be connected to the Profiler to enable some manual operations. They must be connected on the nodes of a matrix with - 4 columns connected to HDR1, pins 10, 11, 12 and 13 (P4.3 to 6) - 3 rows connected to HDR1, pins 7, 8 and 9 (P4.0 to 2). Buttons functions : BP42 : Go home X,Y and Z BP62 : Go home Z only (up) BP52 : X+ (to right) BP32 : X- (to left) BP51 : Y+ (to back) BP31 : Y- (to front) BP41 : Z+ (down) BP61 : Z- (up) BP30 : Change mode (Local, DCC, HPGL Line, HPGL Plot) BP40 : [Not used] BP50 : The current pos become the new "Home" BP60 : Toggle On/Off of the output SPDL (spindle motor) Note : the key number are from the P4 bits number, in column/row order. Ie :BP62 : col=P4.6, row=P4.2. It should be used only to locate them electrically. The better physical disposition cannot be done until all the functions will be known. ------------------------------------- A 4 lines x 20 char LCD display can be connected to the profiler main board. It will display the profiler status, its work mode (3 modes: DCC, HPGL line, HPGL plot), the coords X Y and Z, the trap events, etc. There are around 40 messages (full list below in the thread). D0 to D7 : HDR3 pins 37 to 44 respectively RS : HDR3 pin 45 E : HDR3 pin 46 RW : HDR3 pin 47 The 8 data wires (pins 37 à 44) are bufferised by the HC245 near the pins (IC10), but the 3 others that comme from A0 and from the CLPD pins 30 and 29 are not. Be carefull. Note : the embeded software uses the "status" LCD bit, so the RW line is mandatory. ------------------------------------- When the jumper JP1 (labelled "NO AH") is closed, the profiler elecronics will start without searching the "0" points ons the three axes. That enable a PC to comunicate with the board even if it is not connected to the mechanic, ie to do some tries around an LCD ------------------------------------- The two empties places IC1 and IC3 (under the processor board) would enable to set in place a DAC (IC1) + AOP (IC3), that would generate an analog voltage outputed on the J18 connector (0-10VCC), ie to drive an analog controled speed drill. I have not still found the IC1 16 pins chip. Its pinout would be : 1 : Vcc 16 : to +5V through R64 2 : Gnd 15 : analog output to IC3 3 : Gnd 14 : to +5V and C11 4 : d7 (HDR3.20) 13 : Gnd 5 : d6 (HDR3.19) 12 : Gnd 6 : d5 (HDR3.18) 11 : d0 (HDR3.13) 7 : d4 (HDR3.17) 10 : d1 (HDR3.14) 8 : d3 (HDR3.16) 9 : d2 (HDR3.15) [pins 2, 3, 14 and 15 corrected on 04/18th. I apologize] The 8 lines d0 to d7 are driven by an ULN2803 (IC7), ouput collector. R57 to R62 are the required pullup for these lines. If someone know it, please let know its ref here ! ------------------------------------- HDR2.16 (not wired) is the Tool Change output (open collector from an ULN2003). It can drive a +5 level out and is toggled by the command @TC n; with n=0 or 1 ------------------------------------- A few open collectors output (from a an ULN2003) not wired can drive a led (cathode to the output, anode to +5V through a resistor). HDR2.17 : the led will light during pause, halt, wait (@WT) PU and PD commands. HDR2.18 : the led will light when the profiler leave the mode 0 (Local mode). HDR2.19 : the led will light on software error (ie bad parameter given to a command). A bientôt !

pk1 254 posts Power User	14-04-2008 15:13 Hi Pascal, interesting feature, you wrote about. Two questiones: A 4 lines x 20 char LCD display can be connected to the profiler main board. It will display the profiler status, its work mode (3 modes: DCC, HPGL line, HPGL plot), the coords X Y and Z, the trap events, ... around to 40 messages. What kind of switching enables 40 messages? I guess, they can't be shown at the same time. Did you realize this Profiler-competition so it's shure that Profiler-firmware supports LCD-output? (I remember several red buttons for motor, vacuum ... without firmware support) Greetings Peter
koolr 30 posts Occasional Visitor	14-04-2008 23:17 To PK1 The Red buttons for motor and toolchange does work, for vacuum I don't know. You need to acces the file Colinbus.dat with Microsoft Access and change the appropriat entries. The password to the file was entert somewhere in the forum some time ago and is:COLt657916 Sorry for my English, it's not my native language. Ronald
pk1 254 posts Power User	15-04-2008 08:20 Hi Ronald, thanks for informations. Colinbus.dat has changed with ColiDrive81, couldn't open it with Access 2003, no problems with ColiDrive44. Peter
djam1 13 posts Popping In	16-04-2008 12:26 Hi Pascal, RE: IC1 I have pins 2 and 3 connected to ground. Looks like it might be a AD7524, TLC7524 with the connections used backwards, ref as the output and out 1 as the reference voltage. I expect IC2 is a zener or voltage reference. Regards, Darren
Pascal 6 posts Popping In	18-04-2008 20:06 Hi all ! To PK1 : What kind of switching enables 40 messages? I guess, they can't be shown at the same time. The differents messages are displayed from the status of the profiler. I suspect that the 4 lines HDR1 pins 10 to 13 and the 3 lines HDR1 pins 7 to 9 may be used to switch the controler in differents states : the software checks 1 line at 0 while the other are at 1 in each group. I have not commented these routines, so i do not know more about their usage. Did you realize this Profiler-competition so it's shure that Profiler-firmware supports LCD-output? No, it is not a "competition" only an information. I am sure it works because I have commented all the assembler source that drive it, then I retrieved all pins that are used from hardware and I confirmed them with an oscilloscope check. I will buy a display this week Below are all the messages : MsgEOT: DC.B "!EOT",Car_CR,Car_LF MsgErr: DC.B "!ERR",Car_CR,Car_LF MsgRDY: DC.B "!RDY",Car_CR,Car_LF DC.B "!BSY",Car_CR,Car_LF MsgEscUC: DC.B CarESC,"UC:",Car_CR,Car_LF Msg4Z3Z: DC.B " 0000.000",Car_CR Msg3Z3Z: DC.B " 000.000",Car_CR,Car_CR MsgIdVer: DC.B "ID : 707602-0001 V 1.10 - 14/11/05 ",Car_CR,Car_LF MsgSetCfg: DC.B "SETTING DEFAULT CFG !

Looks like it might be a AD7524, TLC7524 with the connections used backwards, ref as the output and out 1 as the reference voltage. I expect IC2 is a zener or voltage reference Thank you very much !!! You are right, the pins 2 and 3 are connected to ground, not to Vcc. It is a mistake from me. I will get a look on it. But I will first look for in the asm source what commands are used to setup the output voltage. Post edited by Pascal on 18-04-2008 21:19
