ERASynth

ERASynth uses Arduino Due to run the device. Also there is ESP8266 connected to Arduino with serial connection. It is the base of interface. With ESP8266, ERASynth has become platform-independent project. You only need to have web-browser to control your device.ERASynth basicly runs a Arduino code. So anyone who is interested in Arduino can develop own his code and make ERA Synth better.

Install

You only need the Arduino IDE to compile and upload. We have three part of code.

• Arduino DUE
• ESP8266
• ESP8266 HTML Data

To compile ESP code you need to update Arduino IDE board manager. You can find instructions at following link: https://github.com/esp8266/Arduino

For detailed instructions, please go to our web site and you can find user guide.

erasynth-firmware's Issues

Enhancement Request: Reference frequency offset/scale factor

Currently, it is assumed by the firmware that the reference frequency is exactly 10MHz. Even when in spec., the TCXO/OXCO can be a few Hz out.

Since it's not adjustable at the hardware level, I suggest that the ability to enter the real reference frequency be added to the firmware. This could then be used to internally scale the frequencies requested by the user such that the output frequency matches the requested frequency as closely as possible.

I'd suggest that such a real frequency value should allow resolution of milli-Hertz or better (even though most will not be able to measure it that accurately).

Does not work with my ERAsynth (Basic not a + or ++ version)

When installing this version the ERAsynth does not work below 30 MHz and gives the wrong frequency, PLL not locked. When using "Low spurious mode" above 30 MHz the ERAsynth is not locked and gives wrong frequency, when entering "Low Phase noise mode" the frequency is correct.

When downgrading to previous version of FW V2, ERAsynth works below and above 30 MHz, but "Low spurious mode"/"Low Phase noise mode" functions are not present.

Serial communication interferes with sweep triggering, + suggestion

Hi all,

As communicated by email, it is important that there is no communication over the serial port while doing triggered sweeps, because the processor's handling of the serial I/O interferes with the timing of the interrupt that is used to proceed to the next sweep step.

This fact needs to be prominently documented. (It would be even better if it were fixed but I realize that could be pretty difficult).

As an added suggestion:

It would be very helpful if there were a way to query the final sweep frequency and total number of trigger events processed over the serial interface. As per the preceding remark, this should not be done while a sweep is in progress; but for a client program driving the Erasynth, it would be very useful to be able to check these values after performing a sweep, to verify that no triggers were lost. (Which can happen if triggers come in at more than 2 kHz, or if there was serial communication during the sweep, or if there's some electronics problem).

I think adding such variables to the instrument's internal state and exposing them over the serial port should not be too hard.

Command to disable all the printing to the serial port

Hi folks!

We have 3 ERASynth modules and are trying to use it in automated experiments that requires reliability and fast communication. Unfortunately the serial communication with the instruments is terrible for that.

Namely, why are the debug prints enabled by default?

erasynth-firmware/ERASynth/ERASynth.ino

Line 103 in e5cb59e

boolean isDebugEnabled = true;

Beside that, there are a lot of other print statements to the serial that are not safe-guarded with the if (isDebugEnabled).

I would suggest adding a serial command that allowed to disable all the printing to the serial port except when the device configurations are queried from the device. This would allow to have a nice python driver.

@berjk @edensrock can any of you comment on this?

also, are PR welcome?

PS thank you for bringing these devices to the world, nonetheless :)

ESP8266 Firmware Compilation Issues

Hi guys,

Having some trouble here with getting the ESP firmware to compile in Arduino IDE, under Linux. I get the following errors:

This doesn't seem to be related to the Arduino IDE version, the ESP board definitions I'm using is version 3.0.2.

Internal sweep trigger

It would be very useful to have a trigger output at the mod/trig connector in case of a sweep with internal sweep triggering, e.g a trigger every time the sweep restarts at it's first very point.

In this way, one could do simple frequency sweeps with an oscilloscope and a power detector. Currently, only external triggering is supported, which adds quite some overhead for implementation of simple frequency sweeps.

bricked after update

Please suggest solution :)

After firmware update device remain with green led on, communication over RS232 not possible
