uLCD43-PT(SGC) Stamp BS2px24 serial comunication failed

[hestrada6137]

Hi everybody,
I do have an uLCD43(SGC) display and failed to comunicate with my stamp BS2px24 .
Included is my code that I used:
#SELECT $STAMP
#CASE BS2, BS2E, BS2PE
T1200 CON 813
T2400 CON 396
T9600 CON 84
T19K2 CON 32
T38K4 CON 6
#CASE BS2SX, BS2P
T1200 CON 2063
T2400 CON 1021
T9600 CON 240
T19K2 CON 110
T38K4 CON 45
#CASE BS2PX
T1200 CON 3313
T2400 CON 1646
T9600 CON 396
T19K2 CON 188
T38K4 CON 84
#ENDSELECT

Inverted CON $4000
Open CON $8000
Baud CON T38K4 '+ Inverted

rst PIN 4
is_on CON 0
is_off CON 1
OUTPUT rst

Main:
DO
rst = is_off
PAUSE 200

SEROUT 2, Baud,[$45] ' autobaud

DEBUG "autobaud was sent",CR

SEROUT 2, Baud,["s", 3, 1, 0, $FF, $E0, Yellow Text, $00] 'Send text to screen

rst = is_on
LOOP
END

'Any help is welcomed!, Thank you.

Don't understand that much.

But anyway...

Why are you trying to do inverted communication at 38.4kbaud inverted, shouldn't you be using standard 9600?

Why are you playing with RST?

Why aren't you waiting for an ACK after the Autobaud?

Will your system be writing the '3, 1, 0' as the required 'words' or will it only be writing bytes?

Hi,
Thanks for reply,
this was my last code trying to comunicate,

PAUSE 1000
SEROUT 2\1, T9600,[$45] ' autobaud
DEBUG "autobaud was sent",CR
I will appreciate if you have some code to access such display with any of my uControllers,

I learning 4DGL language, my problem is picaso controller has 5 pins like IO and I need more, can I use Bus IO pins to get information from some switches?
Thank you.

[ESPsupport]

You might find the solution to your problem here http://4d.websitetoolbox.com/post?id=6070636

In 4DGL you can use each of the Bus IO pins indivually

Hi, do you think im having problems with my interface?
Im using the ÎUSB-MB5 and still no connecting with my uController,
do I need to buy the cable ?
Do I need to open a usb cable and connect direct the wires to ucontroller instead to pins?

and no success with bus_Set, bus_Out..


any help welcomed, thanks.

[hestrada6137]

I can send commands via Terminal connect 9600 and working,
so no communication with uprocessors.
thx.

[ESPsupport]

To use the BUS pins individually, eg pin_HI(BUS_0) etc.

You should be right with the MB5.

Can you show a diagram of how you have connected your BS2?

[ESPsupport]

There's some information here about BS2 baud rates.

http://www.emesystems.com/BS2rs232.htm#Baudmode

It seems to tie in with the table you have used, but it might give you some more ideas as to what might be happening

[hestrada6137]

Hi, thanks for reply,
I disconnect the MB5 and connect P2 (Tx) directly to Rx and worked, when I turn off computer and ucontroller and turn it again doesn't worked again.
I checked pin_HI(BUS_0) trying to turn on a LED and nothing, here the code:

#platform "uLCD-43PT_GFX2"
func main()
pin_Set(OUTPUT,13); //pin 13,BUS_5 = pin 17 on J2

repeat
pin_HI(BUS_5);
pause(100);
forever
endfunc

Thank you.

Hi,
another question,
using VISI I can see the gauges and objects on monitor but at time of compile and download nothing on LCD,
I was trying changing some parameters but nothing,
any suggestion?,
Thanks.

[ESPsupport]

Have the files been copied to uSD?

Is the uSD FAT(16) formatted?

Any messages?

Are you try a sample?

[hestrada6137]

Hi,
thanks for fast reply,
I used to format the uSD with an adapter, on windows,
I sent commands from Fat controller and saved some screens and images, then display on LCD, ok
only appears "mounting..." for a long time, I wait for 15 mins and nothing.

my new code for my stamp ucontroller: using LCD as GCS;
' {$STAMP BS2px}
' {$PBASIC 2.5}
Rx VAR Byte
#SELECT $STAMP
#CASE BS2, BS2E, BS2PE
T1200 CON 813
T2400 CON 396
T9600 CON 84
T19K2 CON 32
T38K4 CON 6
#CASE BS2SX, BS2P
T1200 CON 2063
T2400 CON 1021
T9600 CON 240
T19K2 CON 110
T38K4 CON 45
#CASE BS2PX
T1200 CON 3313
T2400 CON 1646
T9600 CON 396
T19K2 CON 188
T38K4 CON 84

It works only when disconnect Rx starts to accept commands, if not disconnected , gets stucked,
Thanks for your support.

ViSi programs are for when you have the GFX PmmC loaded into the display.

FAT Controller and serial commands are for when you have the SGC PmmC loaded into the display.

Click the GFX or SGC tab under one of the products http://www.4dsystems.com.au/prod.php?id=114

Your posts seem rather confused, initially I thought you were flipping between the two, but now I'm not so sure.

[hestrada6137]

Hi,
I'm switching between two modes GFX and SGC,
I would like to run under SGC but if doesn't work try GFX,
my problem with GFX is not all ports are working as expected, I need like 10 ports as inputs and outputs
Im testing with both,
thanks.

[ESPsupport]

You aren't trying to take more than 3ma from the port are you?
