The '''ARMFLY AX-Pro''' is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, with 1 additional analog channel (theoretically 2, but only one of them can be used at a time; 3MHz analog bandwidth). Has been proven to be possible to work at 24MS/s also for the Analog channel even if the ADC max sample rate is 20MS/s (see resources).

It is a clone of the [[CWAV USBee AX-Pro]]. There is an "[http://item.taobao.com/item.htm?id=12503749579 RS232 RS485 RS422 CAN converter]" add-on board which also has a BNC connector for analog support.

In sigrok, we use the open-source [[fx2lafw]] firmware for this logic analyzer.

'''Note''': [[fx2lafw]] currently doesn't support switching between the two possible analog channels, ACH1 will be used unconditionally.

See [[ARMFLY AX-Pro/Info]] for some more details (such as '''lsusb -v''' output) on the device.

== Protocol ==

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

== Hardware configuration (V.5) ==
* PA0 -> Select the Analog Source (Channel 1 or 2)
* PA1-7 are not connected
* CTL0 -> not connected
* CTL1 (connected with RDY1) -> CLK Pin (external)
* CTL2 -> provide the clock to the ADC
* PORTB -> Digital Data (8 pins, external)
* PORTD -> ADC Data
