Logic analyzer, CY7C68013+e2prom+74LVC8T245 solution, data from NanoDLA.
The main chip uses CY7C68013A-56PVXC, which is easier to solder.
The 24c64 used by e2prom is actually not so large, but I don’t have a small capacity one. If you switch to a small-capacity e2prom, such as 24c02, A0 needs to be grounded.
Using a 74LVC8T245 is actually too luxurious. This thing is used for level conversion, but it still has some uses.
It has been tested on the board and it works very well.
It comes with burning iic and burning tools. The burning tutorial is as follows.
After soldering, connect the device, install [cy7c68013 driver] in the device manager,
open CyConsole.exe,
check if there is a device in Select Device,
click Options/EZ-USB Interface, enter the new page,
click Lg EEPROM, and select fx2lafw-sigrok-fx2-8ch-c0. After iic
burning, re-plug and unplug the device
driver to install the software. Please see the original project README.
Note: If there is data in e2prom, you need to disconnect SDA, that is, the R7 0R resistor, in order to be recognized by the software. After connecting to USB and powering on, attach R7 and burn the iic file.
