Crate gallo 

Command-line interface for the Pico de Gallo USB bridge.

The gallo CLI provides direct access to I2C, SPI, UART, GPIO, PWM, ADC, and 1-Wire peripherals connected through a Pico de Gallo device. It is built with clap and supports:

• I2C: bus scanning, read, write, and write-then-read operations
• SPI: read, write, full-duplex transfer, and write-then-read
• UART: read, write, flush, and baud rate configuration
• PWM: duty cycle control, enable/disable, frequency/phase configuration
• ADC: single-shot reads, configuration queries
• 1-Wire: reset, read, write, strong-pullup write, ROM search
• GPIO: read/write pins, edge event monitoring with subscribe/unsubscribe
• Configuration: set I2C/SPI/UART bus frequencies and SPI mode
• Device management: list connected devices, query firmware version

Examples

$ gallo list
$ gallo version
$ gallo i2c scan
$ gallo i2c read -a 0x48 -c 2
$ gallo i2c write -a 0x50 -b 0xDE 0xAD
$ gallo spi transfer -b 0x01 0x02 0x03
$ gallo set-config --i2c-frequency 400000 --spi-frequency 1000000

Output Formats

Read data can be displayed in three formats via the -f / --format flag:

• hex (default): hexadecimal byte dump
• binary: raw bytes written to stdout
• ascii: printable characters shown, non-printable replaced with .
