HydraFW Binary mode guide

HydraFW Binary mode guide

This guide is updated towards firmware release HydraFW v0.11 and later

Binary mode description:

Like the bus pirate, HydraBus can be used inwith a more compact protocol which allows scripting its usage

• Syntax is similar to bus pirate (where applicable)
• Currently supported modes :
  • Raw-wire
    • 2-WIRE (Since 3679dc0601220ee4ac897d7e3af4cb59b545e984)
    • 3-WIRE (Since a9681c5e39155f7ae1b6e1b2668950ef70b1223b)
  • I2C (Since 53ab788fa02beac41ae7e1d3e392f5bc38fd8b83)
  • SPI (Since a6c9697a7f69feabd5f0452d7940fcfad4630b5e)
  • JTAG/OpenOCD (Since f5350d1e25358f6e86d496d035a172ea5c7baa81)
  • CAN (Since da87a52f0078185c5a3df9d2279181216ec442a1)
  • PIN (Since e9451c71dfbe44fe5623be493c0cfa1c307aae29)
  • NAND Flash (Since 0685c439a9765073dd5848872f7f174ed7bbe8aa)
  • SMARTCARD (Since e93be6ced16bcbc0faacd2ac24fa5fa1bedf6d0e)
  • NFC Reader (Since 0264ac7515d2811576b6db2af00ab7878686ee3e)
  • MMC (Since 532e4ed70666062f10f2fe47bd6108e64f4e9e10)
  • SDIO (Since 28deb4fdfefc1e2d2a41c364197147b16e42d8c3)
  • Auxiliary pins (Since 858de3f1fe260b07ad0d0893f3bded5ee730b018)

Note All hex (0x00) or binary (0b00000000) values below represent a raw byte, not an ASCII string.

Usage

Enter binary mode

Send 20 0x00 (null bytes) to Hydrabus. It should then respond with the string BBIO1

Main mode commands

• 0b00000000 Reset binary mode. Returns BBIO1
• 0b00000001 SPI mode Returns SPI1
• 0b00000010 I2C mode Returns I2C1
• 0b00000011 UART mode Returns ART1
• 0b00000100 1-Wire mode Returns 1W01
• 0b00000101 Raw-wire mode Returns RAW1
• 0b00000110 JTAG/OpenOCD mode. Returns OCD1
• 0b00001000 CAN mode Returns CAN1
• 0b00001001 PIN mode Returns PIN1
• 0b00001010 NAND Flash mode Returns FLA1
• 0b00001011 SMARTCARD mode Returns CRD1
• 0b00001100 NFC Reader mode Returns NFC1
• 0b00001101 MMC mode Returns MMC1
• 0b00001110 SDIO mode Returns SDI1
• 0b00001111 Returns to console mode. (Ctrl-O (SI) can be pressed if you need to exit Binary Mode from a Console Terminal app). Returns Hydrabus

Utilities

• 0b00010100 Read ADC (PA1). Returns 2 bytes with the ADC value (big-endian).
• 0b00010101 Read ADC (PA1) continuously. Returns ADC values continuously. Stop by sending 0x00.
• 0b00010110 Read PWM frequency (PC6). Returns frequency in Hz (4 bytes), then duty cycle in % (4 bytes).

Auxiliary-pins

• 0b11000000 Read auxiliary pins
• 0b1101wxyz Write auxiliary pins
• 0b11100000 Read auxiliary pins mode
• 0b11110000 Set auxiliary pins mode

Auxiliary-pins are not available for all BBIO modes see each BBIO mode to check if available.
