|
## What
|
|
|
|
Cycles through 4 predefined HID 26-bit (H10301) raw card IDs, simulating each one in sequence automatically.
|
|
|
|
## Why
|
|
|
|
When you have multiple known-valid HID credentials and want to try them all at a reader without manual intervention. Edit the source with your target IDs, compile, and the device will automatically cycle through each one at the reader.
|
|
|
|
## How
|
|
|
|
1. The firmware contains 4 hardcoded raw HID values
|
|
2. On startup, it selects the first slot and begins simulating
|
|
3. After each simulation interval, it advances to the next slot
|
|
4. The cycle repeats continuously until exit
|
|
|
|
## LED Indicators
|
|
|
|
| LED | Meaning |
|
|
|-----|---------|
|
|
| **A/B/C/D** (binary) | Currently selected slot number |
|
|
|
|
## Button Controls

|
|
| Action | Effect |
|
|
|--------|--------|
|
|
| **USB command** | Exit standalone mode |

## State Machine

[*] --> Sim_Slot0 : Startup
|
|
|
|
Sim_Slot0 --> Sim_Slot1 : Auto-advance
|
|
Sim_Slot1 --> Sim_Slot2 : Auto-advance
|
|
Sim_Slot2 --> Sim_Slot3 : Auto-advance
|
|
Sim_Slot3 --> Sim_Slot0 : Auto-advance (cycle)
|
|
|
|
Sim_Slot0 --> [*] : USB data received
|
|
Sim_Slot1 --> [*] : USB data received
|
|
Sim_Slot2 --> [*] : USB data received
|
|
Sim_Slot3 --> [*] : USB data received
|
|
```
|
|
|
|
## Customization
|
|
|
|
Edit the raw ID array in the source code before compiling:
|
|
|
|
```c
|
|
// Example: change these to your target IDs
|
|
static const uint32_t ids[] = {
|
|
0x2006EC0C86, // Slot 0
|
|
0x2006EC0C87, // Slot 1
|
|
0x2006EC0C88, // Slot 2
|
|
0x2006EC0C89, // Slot 3
|
|
};
|
|
```
|
|
|
|
## Compilation
|
|
|
|
```
|
|
make clean
|
|
make STANDALONE=LF_MULTIHID -j
|
|
./pm3-flash-fullimage
|
|
```
