The ARMFLY Mini-Logic is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate.
It is a clone of the CWAV USBee AX-Pro, but it doesn't have analog (only 8-channel digital) sampling capabilities. There is an "RS232 RS485 RS422 CAN converter" add-on board for more functionality (not supported in sigrok, though).
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See ARMFLY Mini-Logic/Info for more detailed information on the device.
Hardware
- Main chip: Cypress CY7C68013A-56LTXC (FX2LP)
- I2C EEPROM: Atmel ATML920 24C02N SU27 D
- Low-dropout voltage regulator: Advanced Monolithic Systems AMS1117-3.3
- 24MHz crystal: 24.000

Protocol
Since we use the open-source fx2lafw firmware for this device, we don't need to know the protocol.
