HydraFW commands

I recommend Putty for terminal to be used with HydraBus hydrafw connected with USB1 or 2 When connected type h for help and use TAB key for completion, you can also use arrow up or down for history. mount, umount, ls, cat & erase work only when a micro SD card is inserted in HydraBus.

For microSD read performance test results (command sd_rperfo) see: https://github.com/bvernoux/hydrafw/wiki/HydraBus-microSD-read-perfomance

##HydraFW (HydraBus/HydraNFC) v0.3-beta a1c311e 2014-10-31 supported commands: ###1) HydraBus AND/OR HydraNFC:

? or h         - Help
clear          - clear screen
info           - info on FW & HW

ch_mem         - memory info
ch_threads     - threads

mount          - mount sd
umount         - unmount sd
cd <dir>       - change directory in sd
pwd            - show current directory path in sd
ls [opt dir]   - list files in sd
cat <filename> - display sd file (ASCII)
hd <filename>  - display sd file (HEX)
sd_rperfo      - sd read performance test
erase          - erase sd

###2) HydraBus only: m - Change mode i - Mode information

####2-1) Mode supported (with command m): 1=HiZ, 2=SPI, 3=UART, 4=I2C

####2-1-1) Mode HiZ options supported (with command m 1): This mode is just a safe mode (all I/O are set in HiZ) This mode can be also use to test protocol interaction commands.

####2-1-2) Mode SPI options supported (with command m 2): SPI device number: 1=SPI1, 2=SPI2 SPI Mode: 1=Slave, 2=Master SPI Freq depending on device number: SPI1 Freq: 1=0.32MHz, 2=0.65MHz, 3=1.31MHz, 4=2.62MHz, 5=5.25MHz, 6=10.5MHz, 7=21MHz, 8=42MHz SPI2 Freq: 1=0.16MHz, 2=0.32MHz, 3=0.65MHz, 4=1.31MHz, 5=2.62MHz, 6=5.25MHz, 7=10.5MHz, 8=21MHz SPI Clock Polarity(POL)/Phase(PHA): 1=POL0/PHA0, 2=POL0/PHA1, 3=POL1/PHA0, 4=POL1/PHA1 SPI LSB/MSB Transmitted First: 1=MSB Tx first, 2=LSB Tx first

Hardware Info: Pins=SPI1 CS=PA15, SCK=PB3, MISO=PB4, MOSI=PB5 Pins=SPI2 CS=PC1(SW), SCK=PB10, MISO=PC2, MOSI=PC3

Example for SPI1:

m 2 1 2 8 4 1

1. SPI mode: 2

2. SPI device number: 1=SPI1,

3. SPI Mode: 2=Master,

4. SPI1 Freq: 8=42MHz,

5. SPI Clock Polarity(POL)/Phase(PHA): 4=POL1/PHA1,

6. SPI LSB/MSB Transmitted First: 1=MSB Tx first

When a mode is fully configured you can use "Protocol Interaction" commands.

####2-1-3) Mode UART options supported (with command m 3): UART device number: 1=UART1, 2=UART2 UART Freq: 1=300bps, 2=1200bps, 3=2400bps, 4=4800bps, 5=9600bps, 6=19200bps,7=38400bps,8=57600bps,9=115200bps, 10=31250bps, manual up to 10.5mbps UART Parity: 1=8/none, 2=8/even, 3=8/odd UART Nb Stop Bit: 1=1 stop, 2=2 stop

Hardware Info: Pins=UART1 TX=PA9, RX=PA10

####2-1-4) Mode I2C options supported (with command m 4): I2C Freq: 1=50KHz, 2=100KHz, 3=400KHz This mode support only Master I2C.

Hardware Info: Pins=I2C1 SCL=PB6, SDA=PB7

####2-2) Protocol Interaction [ Start (for SPI means Enable Chip Select)

] Stop (for SPI means Disable Chip Select)

{ Start with Read (for SPI means Enable Chip Select)

} Stop (for SPI means Enable Chip Select)

: Repeat (e.g. r:10)

& DELAY us (support optional repeat :)

% DELAY ms (support optional repeat :)

123 0x12 0b110 Send 8bits val (support optional repeat :)

r Read (support optional repeat :)

During a blocking read or write which wait for data(for example Slave mode) you can abort the wait by pressing HydraBus UBTN, else you can also wait timeout which is about 10s.

###3) Additional commands for HydraBus+HydraNFC:

nfc_mifare     - NFC read Mifare/ISO14443A UID
nfc_vicinity   - NFC read Vicinity UID
nfc_dump       - NFC dump registers
nfc_sniff      - NFC start sniffer ISO14443A
nfc_sniff can be started by K3 and stopped by K4 buttons
