ATS-MINI Dashboard

[virenderscideas]

Hi Everyone,

Build this https://tarang-wine.vercel.app/, to control ats-mini remotely over wifi network (Use AP),

ats-mini.ino.partitions.zip
device flash

Memory list
memories.zip

use https://thelastoutpostworkshop.github.io/ESPConnect/ to upload memories.json using LittleFS tools

still in early stage, suggestions and feedbacks are welcome.

Regards,
Virender

Hi!Where can I view the source code of the "ATS-MINI Dashboard" project? Very interesting.

[virenderscideas]

Hi,

it still in development phase.

[RadioHam25]

Ок.

When I try to connect to Wi-Fi with version 10.1.1.1, I get this error and I can't enter my Wi-Fi password or username at all. I get the error: "Error: /index.html.gz not found in LittleFS". I hope you fix this error as soon as possible.

[virenderscideas]

Although, index.html.gz is old development (in beginning stage) and shifted to https://tarang-wine.vercel.app. As index.html size grow then decided to keep it outside from firmware.

However, here is the file.

Try to access it by specifying. http://10.1.1.1/config

Which ESP32-S3 controller pin will be used to decode CW, PSK31, etc. signals? Will the RTTY signal also be decoded?

Hi RadioHam25,

Decoders are still in development, I have to modify ATS-MINI hardware on my end first, Although I included it into firmware to show the direction of development.

However, I used PIN 11 in firmware

// =============================================================
// Audio Input
// =============================================================
//
// Audio is read from ESP32 GPIO 11 via ADC.
// Wire SI4732 audio output -> voltage divider -> GPIO 11.
//
#define DECODER_AUDIO_PIN 11

Hello! virenderscideas

Decoders are still in development, I have to modify ATS-MINI hardware on my end first

Alternatively, a signal decoder circuit can be made using LM386 and LM567 chips. This is done, for example, in the ATS-25 radio receiver.

However, I used PIN 11 in firmware

I think this is the right solution, GPIO 11. The fact is that one of the authors of the firmware (H.J. Berndt) for the ATS-Mini radio receiver also used GPIO 11 as an audio input for the CW and RTTY decoder.
http://www.hjberndt.de/dvb/pocketSI4735DualCoreDecoder.html#eibi:~:text=Diese%20Firmware%20funktioniert%20auch%20ohne%20Hardware%2DModifikation.

H.J. Berndt I also used a digital microphone (INMP441) to decode the signals, which I think will be better and more promising. + It will ensure hardware compatibility between the firmware versions.

http://www.hjberndt.de/dvb/pocketSI4735DualCoreDecoder.html#eibi:~:text=Modifikation%20I2S%2DMikrofon%20%2D%20F%C3%BCnf%20Leitungen%20Verbinden%20Mikro%20und%20ESP32%2DS3

I think that in your firmware, you can also use a digital microphone to decode signals.

If possible, it would be good to (for the future), to provide a level switch to GPO1=1/0 (Si4732, 4-pin), in case of upgrading the ATS-Mini, to be able to switch AM-FM antennas.

If possible, it would be nice to add to Menu->Settings the turning on and off of the auto tuner chip capacitor.Si4732. Auto Tuner (On / Off).

/
// Switch radio to given band
//
void useBand(const Band *band)
{
// Set current frequency and mode, reset BFO
currentFrequency = band->currentFreq;
currentMode = band->bandMode;
currentBFO = 0;

if(band->bandMode==FM)
{
// rx.setMaxDelaySetFrequency(60);
rx.setFM(band->minimumFreq, band->maximumFreq, band->currentFreq, getCurrentStep()->step);
// rx.setTuneFrequencyAntennaCapacitor(0);
...
// Set the tuning capacitor for SW or MW/LW
// rx.setTuneFrequencyAntennaCapacitor((band->bandType == MW_BAND_TYPE || band->bandType == LW_BAND_TYPE) ? 0 : 1);

Auto Tuner (On), This may be necessary for those who have V1 or V2 radios. These radios do not have a Hi-Z field-effect transistor on the antenna input. You can connect ferrite and loop antennas to the radio and experiment with them. The Si4732 automatic tuning chip will automatically tune these antennas into resonance. This is convenient. For those who have V3, V4, or higher radios, the automatic tuning chip capacitor is not important and can be disabled. Auto tuner (off). Starting with version V2.21, the chip's autotuner capacitor is disabled by default.

If possible, it is recommended to set the clock (Menu-> Settings-Up time-> Set time-> Hours, Minutes). To be able to display EiBi information without syncing via Wi-Fi or RDS.

If possible, double the font size of the settings functions.

Hello! virenderscideas
It would be nice to add an aviation band to the radio for use with a 118-138 MHz to 8-28 MHz converter.

Preferably with two down-conversion bands, at 100 MHz and 110 MHz, depending on the converter used.

[virenderscideas]

How it work when there is si4732 limitation on vhf band. I know how downconverter works. it will down convert 118Mhz to 18Mhz and 138Mhz to 38Mhz, 110Mhz to 10Mhz.

I can put these new band but doesn't get what you want to achieve and how radio behave when these band selected. Do you want automatically shift radio scale to actual down convert frequency?

[virenderscideas]

Hi @RadioHam25

I can only do minor hardware modification and only focus on firmware and web application.

[RadioHam25]

Hello virenderscideas!
It's clear, friend. If possible, make changes to the software separately.

1. If possible, it would be good to (for the future), to provide a level switch to GPO1=1/0 (Si4732, 4-pin), in case of upgrading the ATS-Mini, to be able to switch AM-FM antennas.
2. If possible, it would be nice to add to Menu->Settings the turning on and off of the auto tuner chip capacitor.Si4732. Auto Tuner (On / Off).

/
// Switch radio to given band
//
void useBand(const Band *band)
{
// Set current frequency and mode, reset BFO
currentFrequency = band->currentFreq;
currentMode = band->bandMode;
currentBFO = 0;

if(band->bandMode==FM)
{
// rx.setMaxDelaySetFrequency(60);
rx.setFM(band->minimumFreq, band->maximumFreq, band->currentFreq, getCurrentStep()->step);
// rx.setTuneFrequencyAntennaCapacitor(0);
...
// Set the tuning capacitor for SW or MW/LW
// rx.setTuneFrequencyAntennaCapacitor((band->bandType == MW_BAND_TYPE || band->bandType == LW_BAND_TYPE) ? 0 : 1);

Auto Tuner (On), This may be necessary for those who have V1 or V2 radios. These radios do not have a Hi-Z field-effect transistor on the antenna input. You can connect ferrite and loop antennas to the radio and experiment with them. The Si4732 automatic tuning chip will automatically tune these antennas into resonance. This is convenient. For those who have V3, V4, or higher radios, the automatic tuning chip capacitor is not important and can be disabled. Auto tuner (off).

3. It would be nice to add an aviation band display to the radio for use with the 118-138 MHz to 8-28 MHz converter. For example. When the converter (110 MHz) is connected, the frequency should be displayed in the range of 118-138 MHz. The actual reception frequency of Si4732, (118-138) - 110 MHz? will be 8-28 MHz.

Hello virenderscideas!
How can I save and delete a frequency from memory?

[virenderscideas]

hi @RadioHam25 ,

to update frequency you can use https://thelastoutpostworkshop.github.io/ESPConnect/,

just update memories.json and override existing file in LittleFS after that in setting menu there is a setting to load memories.

memories.json format mention in #356 (comment), there is memories.zip

[RadioHam25]

Good health! Yes, that's what I did. But the result is negative. It shows a memory read error.

How to manually enter the frequency of the tuned radio station displayed on the display into the radio's memory.?

The control panel does not start. It appears for 1 second and then disappears.

[virenderscideas]

at my end it loading properly https://tarang-wine.vercel.app/.

[virenderscideas]

Hi @RadioHam25 ,

Seems after loading memories you did not save changes in espconnect. you have to write your file it will take some time. In ESP connect you have to write LittleFS at top, when you load it just show load in browser but not write in LittleFS, you have to write it from top Options.

In future memories will also be directly uploaded and editable with web client.

I added Auto tuner settings.

Increasing Font size can't be possible with current implementation as TFT_eSPI does not support it. font size scaling possible with font type 1 and custom .vlw font.

Font type 1 scalable but not legible properly and scaling with .vlw increase firmware size as I have to load custom font lib. I already did POC with it and it works when playing with translation part. It possible but increase framework size so discarded at that time.

One feature also there in webclient. which I think worthwhile mention here, If display is in sleep mode then webclient display can make it visible. Just double click on rotary encoder and then after sometime (refresh) display will start showing in webclient.
