ESP32-C3 mini

Also not shown above but I'm confident I managed to set IO_MUX_GPIO2_REG to x001802 inside my modified Espruino build readADC() before any IDF calls , using api calls in the EspIdf GPIO library. Including gpio_reset_pin()
and still experienced the same behaviour on multiple analogRead calls, dispute the register being set as above.
So not sure at all where to go, it does seem Espruino is putting the ADC peripheral in a bad state somehow.

Edit .. I did not try to modify the Espruino ESP32 pin setting code in jshardware.c, which as you say earlier does not currently have an analog option. And I further note that the esp32-c3 IDF ADC library for IDF v5 is very different to the current and current Espruino ADC handling will need a rewrite anyway. Also current GPIO calls in jshardware.c are using HAL level calls and not the IDF GPIO library API so it looks like quite a bit of change and testing to get to v5 in this area.

We will continue to pay attention to your community in the future

Thanks for the update and for checking with the registers changed! It's interesting that the function changed so much in SDK5 though...

I wonder whether maybe there's something about the fact we're using HAL calls for GPIO? Maybe the IDF is expecting something to be in one state but because we set it at a lower level it's different?

The esp32 c3 mini is my new favorite board of the esp family. Yes it could be flash easily the same way as any other and the fact I have found it is way easier than all the other i had done esp8266, esp01, esp 32, esp s2. One notable of the the c3 is even without visible antenna the range is great. The esp32 is the one i had most trouble to the point that i returned them all (bought 3 times) even with external antenna hook up. I kept getting flash failure with wifi not connected from the same distance I had no problem with any other board.

The cost of the esp32 c3 mini is about the same as the esp8266 so it does not make sense with the latter. It is tiny small that makes it even better. 99% of the time people use these esp with most of the pins and feature NOT use. My choice is good enough for my application no more no less. My favorite one is the esp32 c3 mini and the esp01.

May I ask if the AnalogRead of Espruino ESP32 C3 mini can be used normally now?

Not yet, no. If you were able to help with the debugging effort to find out why it isn't working it would be hugely appreciated.

Do you have a solution for the Analog Read of your ESP32-C3-MINI

@SimonGAndrews did you check this Arduino thread?
https://forum.arduino.cc/t/problem-with-analogread-on-esp32-c3/892651

Thanks @MaBe I saw this but ill check the detail again.

May I ask if the AnalogRead of Espruino ESP32 C3 mini can be used normally now?

No, it's still not working. I don't have time to work on this at the moment, but hopefully in a month or so I'll have a bit more time.

About the only thing I can think for now is to comment out all the pin state setting code in Espruino's jshardware.c and see if that fixes it, and if it does we can at least work back from there.

@Gordon and folks , Im confident ive stumbled into a workaround for the analog read issue. It seems using adc1_get_raw(channel) a second time inside readADC will always return a value. Unlike the first time it is used which will retun zero accept the first time it used after a reboot.

My environment currently has too many changes in it (and my GIT knowhow wanting) to offer aPR with the change and ive not tested the simple version of a change. But I suggest repeating line 147 in jshardwareanalog.c , as in the attached , "int value = adc1_get_raw(channel) " ; so that readADC always returns the second assignment of value. This should provide a work around. (Probs dont want the 'int' on the second assignment. ill leave details to a C pro )

In my highly modified version this seems to work .

Background .. To get to this point I was trying to determine if it was just the multiple calls to adc1_get_raw that caused the issue or it was making a call and going back into Espruino, before the next call , causing the issue. So know knowing a second call always returns a value , I suspect the latter and that espruino is somehow upsetting the adc peripherial , however a raw read sorts it out for an immediate subsequent call.

What a mess lol ... ive spent hours on this.

I hope someone can try this simple change for us.

Nice and many thanks for your effort. I will give it a try over the weekend.

you can call git on command line:
git status show the files that are changed
git diff filname show changes
git checkout filname revert changes

@SimonGAndrews this is awesome, thank you so much for spending so much time looking into this! I just tested and it seems to work great - I've now put the change in, so any cutting edge builds (or 2v25 when released) should have a working ADC!

@Gordon Many thanks!

Great news, thanks.

WIFI Errer

user158605

Did you try creating a dedicated topic, with a relevant title, starting with a nice message like "hello guys, how are you doing", and explaining a bit your problem, and what you expect?

Thank you for your answer. My English is not very good, so it's difficult for me to describe it. I need to create a new blog theme now

I have published a new blog with the following link:
https://forum.espruino.com/conversations/398575/

Hi, after our detailed testing; Confirm that WiFi is indeed unable to connect properly; Unable to output information after using WiFi connection code; There is no connection record even when checking the router device

var WIFI_NAME = "123";
var WIFI_OPTIONS = { password : "123456789" };

var wifi = require("Wifi");
wifi.scan(function (err, networks) {
    console.log(err, networks);
    wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
      if (err) {
        console.log("Connection error: "+err);
        return;
      }
      console.log("Connected!");
    });
});

please stop posing same issue in this conversation too.

Hello everyone. I've been disconnected for the past three months. I wanted to make progress and help out, but I couldn't focus until the holidays.

I've just started getting back into the project. I already have the environment downloaded from GitHub and the ESP-IDF 4. Furthermore, I've tested both ESP32C3 and ESP32, and both generate the firmware without errors. I haven't tried uploading the firmware to the boards yet.
