o.k. so etwas habe ich mir gedacht.

wo müsste ich das tx0 einbauen?

Code:
Mcp2515_read_register Txb0ctrl                              '&HA0
'Print "SPI_read_Status0: " ; Canin
If Canin.3 = 0 Then Gosub Send_buffer0
Mcp2515_read_register Txb1ctrl                              '&HA0
'Print "SPI_read_Status1: " ; Canin
If Canin.3 = 0 Then Gosub Send_buffer1
Mcp2515_read_register Txb2ctrl                              '&HA0
'Print "SPI_read_Status2: " ; Canin
If Canin.3 = 0 Then Gosub Send_buffer2
dann springt er in die einzelen buffer

z.B.
Code:
'---------  senden mit Buffer 0
Send_buffer0:
 Hilf1 = Id / 8
 Idh = Hilf1
 Hilf1 = Idh * 8
 Hilf1 = Id - Hilf1
 Hilf1 = Hilf1 * 32
 Idl = Hilf1
  'Priorität einstellen bit 1-0 11=>höchste / 10=>hoch
  '                             01=>niedrig / 00=> niedrigste
  Mcp2515_bitmodify Txb0ctrl , &B00000011 , &B00000011
  'Standard ID einstellen
  Mcp2515_write_register Txb0sidh , Idh
  Mcp2515_write_register Txb0sidl , Idl
  'Nachrichtenlänge einstellen (DFL)
  Mcp2515_write_register Txb0dlc , Dfl
   'Daten
  Mcp2515_write_register Txb0d0 , Db0(1)
  Mcp2515_write_register Txb0d1 , Db0(2)
  Mcp2515_write_register Txb0d2 , Db0(3)
  Mcp2515_write_register Txb0d3 , Db0(4)
  Mcp2515_write_register Txb0d4 , Db0(5)
  Mcp2515_write_register Txb0d5 , Db0(6)
  Mcp2515_write_register Txb0d6 , Db0(7)
  Mcp2515_write_register Txb0d7 , Db0(8)
  'nachricht versenden
  Reset Css
   Waitus 10
   Mcphilf = Spi_rts0
   Spdr = Mcphilf
   Do
   Loop Until Spsr.spif = 1
   Waitus 10
 Set Css
 'Print "gesendet Buffer-0"
 Waitms 50


  Return
wieso sind das eigentlich 3 Buffer?
