| 77 | ## Anmerkung ## |
||
| 78 | Der letzte Block ist meistens kleiner als die Blockgrösse. |
||
| 79 | Hier ist dann cmd[1] & cmd[2] entsprechend zu verkleinern ! |
||
| 80 | |||
| 81 | ---- Lesen (für Kontrolle) |
||
| 82 | zu Beginn auf Adresse auf 0x00 setzen (siehe oben) |
||
| 83 | |||
| 84 | cmd[0] = 'g'; |
||
| 85 | cmd[1] = (SendBufferSize >> 8) & 0xFF; |
||

| 87 | cmd[3] = 'F'; |
||
| 88 | SEND_BYTES(cmd, 4); |
||
| 89 | |||
| 90 | Antwort: |
||
| 91 | 1 Block Daten, Länge entsprechend cmd[1] & cmd[2] |
