| | 5 | Changes to PaintGraph to create X axis labels that are snapped to a power of two (useful when analysing low freq tags\r |
| | 6 | with cycle times that are a power of two). Also small changes to keep the X axis labels fixed within the graph window\r |
| | 7 | as the width of the graph window is resized.\r |

| | 13 | FpgaWriteConfWord(data) is now a special case of FpgaSendCommand(FPGA_CMD_SET_CONFREG, data) to avoid changing every\r |

| | 26 | Initial SVN commit plus: |
| | 27 | - Added indala demodulation algorithm - full documentation on https://www.lafargue.name/proxmark3/ |
| | 28 | - losim should also be able to simulate an indala tag after indalademod |
| | 29 | - offline mode for the proxmark3 CLI: if no Proxmark is detected, it will |
| | 30 | still go on, but all commands requiring USB will fail (obviously). |
| | 31 | A proper implementation would require only enabling offline commands |
| | 32 | in this mode. |

| | 39 | Added two new LF commands for tag exploration : |
| | 40 | |
| | 41 | - askdemod: takes 2 arguments, one is the clock rate, one is the modulation |
| | 42 | convention (high mod is 1 or high mod is zero) |
| | 43 | |
| | 44 | This command demodulates the stream into a binary stream into |
| | 45 | the trace buffer (0's and 1's) |
| | 46 | |
| | 47 | - mandemod: manchester decoding of a bitstream: takes a binary stream from |
| | 48 | the trace buffer (see askdemod) and attempts to do manchester decoding |
| | 49 | to it. One argument: clock rate. Outputs the bitstream to the scrollback buffer. |
| | 50 | |
| | 51 | Those two helped me to validate that the unknown tag I had was indeed an EM4100 type of tag |

| | 57 | bootrom/bootrom.c\r |
| | 58 | Significant changes to bootloader. Use of Chip ID register to detect if running on a SAM7S512 then configure FLASH\r |
| | 59 | waitstates as per SummoningDark's suggestion for a SAM7S512 or SAM7S256.\r |
| | 60 | Deleted idle loops waiting blindly for clocks to settle and now using status registers to detect when clocks are stable.\r |

| | 62 | *************************\r |
| | 63 | * IMPORTANT INFORMATION *\r |
| | 64 | **************************************************************************************************************************\r |
| | 65 | * With this boot code, the device can now only be flashed if button is held down after power on or a software reset.\r |
| | 66 | * The flash procedure is this:\r |
| | 67 | * Hold down button. Either plug in USB or software reset it. _While_holding_down_button_ (red and yellow LEDs are lit) you can\r |
| | 68 | * issue one or more of the "prox bootrom <file>" "prox fpga <file>" "prox load <file>", be sure to hold button down for the\r |
| | 69 | * entire duration of the flash process. Only release the button when flashing is complete and you want to let the board boot.\r |
| | 70 | * This process may be less convenient but it's safer and avoids "unintentional" flashing of the board.\r |
| | 71 | **************************************************************************************************************************\r |
| | 72 | LED boot sequence now changed, C (red) lights up when boot code jumps from flash to RAM boot code, A (yellow) lights up after\r |
| | 73 | clocks have been initialized, B (green) lights up when jumping from boot code to main code, then D (red led away from the others)\r |
| | 74 | lights up while code is being downloaded to FPGA, then all leds turn off and board is ready for action.\r |
| | 75 | \r |
| | 76 | With these changes the board now boots and is ready to use in about 3 seconds. Also since the USB bus is not initialized\r |
| | 77 | twice (once during boot, then again when the main code runs) unless the button is held down at boot, this seems to avoid\r |
| | 78 | the double USB connect and "USB device not recognized" when device is connected to the USB bus or software reset.\r |

| | 83 | armsrc/fpga.c\r |
| | 84 | Implemented function SetupSpi() to initialize the Serial Peripheral Interface (SPI) in preparation to adding an LCD to the board.\r |
| | 85 | Changed FpgaWriteConfWord() to use the SPI communication now instead of bit banging the serial data to the FPGA.\r |
| | 86 | \r |
| | 87 | fpga/fpga.v\r |
| | 88 | The FPGA config word serializer required non standard SPI communication (ie for shifting in a 8 bit word, it required a 9th clock\r |
| | 89 | cycle with NCS high to load the word from the shift register to the conf register). This was OK for manually bitbanging it but not\r |
| | 90 | suitable for using SPI comms. The serializer was fixed to load the conf word from the shift register on a NCS lo-hi transition and\r |
| | 91 | not require additional clocking.\r |

| | 97 | LCD driver for PCF8833 based LCDs like those found on Nokia models 2600,2650,3100,3120,5140,6030,6100,6610,7210,7250 maybe\r |
| | 98 | others. These color LCDs have a resolution of 132x132 and a serial interface. They are very cheap like even down to $2/pc\r |
| | 99 | This LCD driver is a straight rip of that found at http://www.sparkfun.com/datasheets/LCD/Jimbo-Nokia-SAM7-Example.zip with\r |
| | 100 | very small changes, mainly to integrate it and make it compile with our codebase. Also comented out the circle subroutines\r |

| | 107 | Fixed a small bug in CmdHIDdemodFSK (added case 4) which prevented reading some tags. When a logic 0 is immediately followed\r |
| | 108 | by the start of the next transmisson (special pattern) a pattern of 4 bit duration lengths is created.\r |

| | 133 | armsrc/appmain.c\r |
| | 134 | Replaced some of the hex value params in FpgaWriteConfWord with more explanatory defines.\r |
| | 135 | Changes to the Tune command as it assumes wrong HF capacitor value (130pF) and produces wrong voltage readings.\r |
| | 136 | Combined some of the integer arithmetic statements to improve accuracy slightly, since the voltage divider ratio is not an integer.\r |
| | 137 | Voltage divider resistor network is 10M/240k = ratio of 41.6666\r |
| | 138 | \r |
| | 139 | Originally the calculation was rounding the ratio down to 41\r |
| | 140 | 3300 (mV) * 41 * sample_value / 1024\r |
