The Sysclk AX-Pro is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, and with 2 additional analog channels.

It is a clone of the CWAV USBee AX-Pro.

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

Note: Only the logic analyzer functionality is supported so far, analog support is work in progress.

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

The analog channels are multiplexed by relay or solid-state IC to one ADC.

#	Pin	Destination	Remark
01	RDY0/SLRD	TRIG	socket pin
13	IFCLK	GND	grounded
18..25	PB0..7	DCH0..7	digital input
30	CTL1/FLAGB	CLK	socket pin
31	CTL2/FLAGC	ADC_CLK	ADC clock input
33	PA0	relay	multiplexing ACH1/ACH2
35	PA2	DCH1 GND	can be isolated from GND and act as aux socket pin
36	PA3	DCH2 GND	can be isolated from GND and act as aux socket pin
38	PA5	STC_P3.1	aux 8051 chip
39	PA6	STC_P3.3	aux 8051 chip
42	RESET#	STC_P3.2	aux 8051 chip
44	WAKEUP	NC	not connected
45..52	PD0..7	ADC_D1..8	ADC data output

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

-* [[EE Electronics ESLA201A]] - the same circuit (from firmware's point of view). PCB has been copied and altered, same silkscreen labels. No electrolytic caps, no resistive trimmers, larger screw-hole-keepouts, no cap on pin 13 at U10, no U13 (second MAX1044/ICL7660). Has extra button inside the box!
