WeAct LogicAnalyzerV1 : A logic analyzer based on Cypress CY7C68013A / Corebai CBM9002A

WeAct LogicAnalyzer V1

WeAct LogicAnalyzerV1 is a logic analyzer designed based on Cypress CY7C68013A/Corebai CBM9002A USB controller. It can collect 8 channels at the same time. The maximum sampling rate of each channel is 24Mhz, and the maximum logical level supports 5.5V. The software adopts sigrok-PulseView, which is open source, and supports Linux, Windows, Mac OS X and other platforms. It supports more than 100 kinds of protocol analysis, and can add its own protocol analysis.

• Sampling rate and number of channels: 24Mhz@8 Channel
• Signal input range: 0-5.5V
• High and low level recognition range: VIH: >2V,VIL: <0.8V
• Communication mode: USB 2.0 (In order to ensure the sampling rate of 24Mhz, try not to use USB docking station)

Begin to use

1. Download sigrok-PulseView Software
2. Install sigrok-PulseView && LogicAnalyzer driver

After PulseView is installed, run Zadig, select the device you want to Install the Driver on, check Edit, change the device name to fx2LAFw, and then click Install Driver

3. Click PulseView to run the software, and the yellow light of the logic analyzer will light up,indicating that the firmware is loaded successfully and the logic signal can be sampled

Q&A

1. Sampling is not up to 24Mhz

Try to connect the logic analyzer to a separate USB port and do not use a USB docking station

2. Why does the acquisition of 10Mhz signal appear distortion

The sampling rate of the general logic analyzer needs to be 3-5 times higher than the frequency of the sampled signal to avoid distortion

3. Why is no firmware provided

Firmware is written online via PulseView, providing little meaning

4. Reprogram or not

Support, their own use of programming, but EEPROM only 2Kbit size

5. Two leds indicate which two channels

The green light indicates CH0 and the blue light indicates CH1

6. TBD
