instead of using $bgf, have a look at $INC which can binary include a file with a label and size.
sending can be done with printbin or when using print make sure you use : print chr(ar(x));
thus chr() function to send as binary, and ; to suppress CR + LF
then you need to alter the driver for the lcd. instead of getting it from eeprom or ram, use waitkey()

Sounds very good too. 
This will take me to the next question.
Now when i Save the incomming Data from the Picture, how can i use SHOWPIC from a Custom Memory location? How does it look like?
Like:
SHOWPIC 0 , 0 , &h00 to &h006 ' ? |

please read the help. there is no option to show from a custom location. and this is a for a reason : you dont have enough space to store the picture in memory.

Hi albertsm
i read the help, this is why i am here.

Can you make a Language Statement like:
SAVE ByteIncomingPicture(6) as BGF at &h268!4OW3ß8 ?
TestPicture = &h268!4OW3ß8
SHOWPIC 0 , 0 , Testpicture
This would be awesome.
best regards |

Which is nowhere described in the help.
I already provided a simple method to send a BGF file, or actually any (binary) data you have. $INC can store a label and size. And it is simple to read and send this data. you should try it.
Only the 'other side' is more work. Either alter the lib (i do not know which driver/lcd you use) and receive direct. Or make 2 steps : receive the data. Then show from memory.
I am willing to make a change to support loading from SRAM. But you need to understand that bgf files can be big in size. Depending on LCD and image. If your biggest bgf file is 8KB, you need a buffer of 8 KB !
Most chips do not have that size. So before i do a lot of work : change compiler, drivers, documentation, testing. Make sure that this is usable. I dont want to work on features that are never used.
When using direct com, there is no limit in size since data is sent byte after byte. but you need some handshake to make sure all is kept in sync.

This sound awesome.
The Recieving MCU using a E32 TTL100 RF Module:
| Code: | $regfile = "m128def.DAT"
$crystal = 7372800
$baud = 19230
$eepleave
'$loadersize = 512
$hwstack = 100
$swstack = 200
$framesize = 200
$Timeout = 100
$lib "glcdKS108.lib" ' KS-108 controler
'$Sim
Config Graphlcd = 128 * 64sed , Dataport = Porta , Controlport = Portc , Ce = 0 , Ce2 = 1 , Cd = 2 , Rd = 3 , Reset = 5 , Enable = 4
Const Serout_extpull = 0
Config Serialout = Buffered , Size = 20
Config Serialin = Buffered , Size = 20
Do
Bitwait Pine.2 , Set
Input DataInput Noecho
' << and save here the Incomming Picture data to show later with SHOWPIC >>
Loop
End |
and an amount BGF Files after the END, that already exist during Compile

Hi Michael,
the above code doesn't really solve anything.
do you want to receive data from bgf file and immediately write it to Display?
otherwise where's your buffer for incoming huge data?
...or did you want someone to supplement your code fragments above?
... which probably will not happen

I want to Recieve a BGF File and want to Store it in the eeprom, and have access when it need to be Shown.
| Quote: | | where's your buffer for incoming huge data? |
What do you mean? Serialin and out are Buffered with the Size of 20. Which i must increase when its nessesary. |

while memory of processor is limited, the EEPROM is certainly limited.
do you already have these bgf files? and what is the byte size of the biggest one?

The biggest BGF of my 137 Pictures in my Project have 987 Bytes (this is the MainMenu Picture with a bunch of Details).
The Most of all other ranges from around 50 to 200 Bytes.
I havent done yet some Pixelwork for the Transmitting Picture, because iam working currently on some Idleing Animations with Pset ,until a "Confirmed" String is Recieved.
I can send you a Similar BGF with the same Dimensions of my already using Submenu´s.
The Picture is 64x32 with 238 Bytes
Edit: there is a Permission, i can not tke a BGF in the attachment here. |

When ive read :
| MichaleB wrote: | | ..(witch can show the BGF file) |
I was think that you have the receiver side done
..and, ofcourse I made mistake in my code. Should be "Printbin" instead "Print". That`s why you see ascii representations of the values.
You must know that BGF must be decompressed by sender and this is some time consuming but spare some flash space.
If you have space in flash then indeed bin file, like Mark propose, will be quicker. |
