Dear Sir,
- The trigger goes to the FPGA through the FMC connector. It allows you to decide when you trigger, it is an external trigger, similar to what a trigger input is on an oscilloscope.
- VADJ is defined by the FMC specification. It is stands for Voltage ADJustable. This voltage comes from the FPGA carrier board and power some IOs. Generally VADJ also power the FPGA banks so there is compatibility between the FMC board IOs and the FPGA IOs.
- Yes, both EEPROM and ADT7411 shares the same i2c bus. The i2c bus pins on the FMC connector is also defined by the FMC specifications.
I hope that helps!
Best Regards,
Arnaud
