0410 v1.0 alive |
| 8 |
0412 v1.1 fixed problem with found, and changed headers |
| 9 |
|
| 10 |
Errors: (returned to the main program as the variable "err") |
| 11 |
err= |
| 12 |
0xFF - data (physics or calibration) from both cards found |
| 13 |
0xF0 - only data from main card found |
| 14 |
0x0F - only data from extra card found |
| 15 |
0x00 - no data found |
| 16 |
