Figure 1. There are two available variants of this mini board: one with a single jumper J1 and another with two jumpers J1 and J2. The board with two jumpers was used to test the FX2LP logic analyzer. See the schematic attached with this knowledge base article KBA. Download PulseView from sigrok for your host OS from this link. This example uses 0x1d50 and 0xd which correspond to the channel logic analyzer.

CY7C68013A EZ-USB FX2LP Development Board
Lcsoft Mini Board
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer. There is a very similar board made by Geeetech, it has near-identical components but a slightly different layout. All the pins on the FX2 LP are broken out to 40 header pins. By default the chip will boot in some internal bootloader which allows loading and executing from USB to the internal RAM. Sigrok will typically use the fx2lafw firmware for this aka "load-on-probe". The Cypress has no DAC and can't by itself have any analog output. Geeetech product page.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. To have the board working with PulseView we need the correct Windows driver - I downloaded it from here. Cypress released a knowledge base article that explains how to use this FX2LP low cost kit with Sigrok PulseView logic analyzer application. So far so good. It recognized my Dev Board immediately and the demo sketch for the arduino is chooching away making sweet traces as it counts.
