The '''HT USBee-AxPro''' is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, with 1 additional analog channel.

It is able to switch between USBee AX-Pro, Salea Logic and Altera USB blaster mode via a button. When pressing the button the USB VID/PID changes.

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

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

See [[HT USBee-AxPro/Info]] for some more details (such as '''lsusb -v''' output) on the device.

Notes:
* Some devices have R2 = 66.5 Ohms instead of kiloohms, this basically limits the range to -3.3V — +3.3V
* TLC5510 is used with ~3.3V "reference" from LDO output which is both out of the allowed range and is a major source of inaccuracy
* Some devices (probably those that do not have U5 populated) produce bogus min and max spikes when measuring certain voltages, this can probably be remedied by adding small (on the order of 10s pF) capacitance to U5 Vcc and GND pins or to the ADC CLK line
* This board was apparently designed by people lacking EE knowledge, do not expect much from it

'''HT_V6.0''':

=== Pin mappings ===

The FX2 CTL2 and PD0..7 pins are mapped exactly like the '''HT2013 V5.00''' version. The TLC5510I OE# pin is tied to GND.
