The Braintechnology USB-LPS is a Cypress FX2 based 16-channel, 24MHz, USB-based logic analyzer and signal/pattern generator.
In sigrok, the open-source fx2lafw firmware and driver is used for this device.
See Braintechnology USB-LPS/Info for some more details (such as lsusb -vvv output) on the device.
- Main chip: Cypress CY7C68013A-56PVXC (FX2LP)
- I2C EEPROM: Atmel ATTiny13-20SU
- 3.3V voltage regulator: LD33
- Crystal: 24MHz
Since we use the open-source fx2lafw firmware for this device, we don't need to know the protocol.
However, for those interested in this, see our old vendor protocol docs.
