Hi @alf45tar

I've rebuilt my Pedalino-8 with the Lilygo T-Display S3, this time I've bought a M-Audio expression pedal and I've added a TRS jack to connect it to the esp board.
Unfortunately and with my big surprise, even if I've added pull-up resistors, a capacitor of 100uF on both input and power, the output is very unreliable, no matter if I use the USB power or the battery. The firmware outputs the correct value but then each second it outputs the max value of 127, when the pedal is full on tip, when the pedal is full toe it outputs half the max value. I saw this in the console and using a midi monitor program. In the console i see a weird "input", with crazy high value in between the right readings from the pedal.
I've tried also to use different gpios without any luck. Moreover, because I'm using 8 foot switches as momentary 2, plus a Midi Out and a TRS jack, I don't have enough gpios to try other solutions. I've also played with the Ease settings and the threshold without any luck.

  1. is there any solution to this behavior? How do you connect the expression pedal if you use any?

  2. would a possible enhancement in the firmware the ability to use an i2c ADS converter like the ADS1115 and use the i2c bus to do all the analog reads? It supports 4 analog inputs. As far as I know it should be way less prone to bad readings coming from the crappy ADC converters in the esp32 boards...

Thanks in advance.

this is what I got in the console:

I'm using D6 and A6 for the analog pedal (GPIO1 and 18), D5 is the MIDI_OUT on GPIO21. This is the PEDALS config:

#elif defined ARDUINO_LILYGO_T_DISPLAY_S3   // https://github.com/Xinyuan-LilyGO/T-Display-S3
#undef  PEDALS
#define PEDALS                7

// Strapping pins: 1, 3, 45, 46
// ADC1:    1-10
// ADC2:   11-20 (19=D- 20=D+) (ADC2 module is also used by the Wi-Fi)
// SPI0/1: 26-32 (usually used for SPI flash and PSRAM)
// SPI0/1: 33-37 (board with ESP32-S3R8 chip not recommended for other uses)
const byte pinD[] = {GPIO_NUM_10, GPIO_NUM_2,  GPIO_NUM_43, GPIO_NUM_44, GPIO_NUM_1, GPIO_NUM_14, GPIO_NUM_0};
const byte pinA[] = {GPIO_NUM_11, GPIO_NUM_12, GPIO_NUM_13, GPIO_NUM_16, GPIO_NUM_18, GPIO_NUM_14, GPIO_NUM_0};
#define FACTORY_DEFAULT_PIN   GPIO_NUM_0    // Button BOOT
#define DIN_MIDI_IN_PIN       GPIO_NUM_1
#define DIN_MIDI_OUT_PIN      GPIO_NUM_21
#define BATTERY_PIN           GPIO_NUM_4    // Pin connected to BAT (BAT is not VBAT)
#define FASTLEDS_DATA_PIN     GPIO_NUM_3
#else

The controls are like "Control 5" --> Pedal 5 - Button empty
The Pedal is set to Analog, and I've tried different settings, no matter what, every second I got that weird input...

Version 3.4.0 is out.

ADS1115 board connections:

  • VDD -> 3.3V
  • GND -> GND
  • SCL -> PIN_Ax
  • SDA -> PIN_Dx
  • ADDR -> GND

Tested on T-Display only.

Hi @alf45tar Very Cool!! I'm gonna buy one to test it. I have the T-Display S3. Where do you define the Pins for SCL and SDA in the T-Display S3 part in Pedalino.h?

It is the digital and the analog pin of the selected pedal. For example if you are selecting the Mode "Analog 4" for Pedal 1, SDA=10 SCL=11.
At the moment you can connect only one ADS1115 but it can be expanded up to 4 ADS1115 for a total of 16 analog inputs.

Fantastic!
I'll have it tomorrow. I'll let you know the outcome. Cheers!

Ok, I'm soldering it, How have you connected the analog source? Considering that now we have just 1 analog input per analog source? I guess it's GND + TIP of the TRS jack connected on the A0 pin of the ADS1115, right?

Good point. Analog pin is usually connected to RING. We do not have a digital ping for TIP. The port is not like the others.
I think I have to redesign the connections using separate pins for SDA and SCL.

Hi @alf45tar,

I'm having a bit of trouble getting the ADS1115 recognized.

I got this in the console as soon I set the "Analog 4", also no buttons seems to work properly when the i2c bus acts like this:

[ 51676][E][Wire.cpp:513] requestFrom(): i2cRead returned Error 263
[ 53678][E][Wire.cpp:513] requestFrom(): i2cRead returned Error 263

[ 61686][E][Wire.cpp:513] requestFrom(): i2cRead returned Error 263

I have the SCL on GPIO_18 (A5) and SDA on GPIO_1 (D5), ADDR to GND.

Do you have pull up resistors on SCL and SDA? I'm using the T-Display S3

Regarding the TIP/RING question, yeah I found out... It's the RING on A0. Thanks.

I'm looking for an i2c scanner, to see if I can see anything.

Ok so....

I've tested a simple i2c scan sketch using SCL and SDA on GPIO_18 and GPIO_1, I did't touch the wiring, and it seems working:

23:11:51.246 -> Scanning...
23:11:51.292 -> I2C device found at address 0x48
23:11:51.292 -> done

Now I'm going to test the ADS1115 library.

The ADS1115 works properly with a simple sketch measuring the voltage:

The Sketch:

#include <Wire.h>
#include <Adafruit_ADS1X15.h>

Adafruit_ADS1115 ads;

float Voltage = 0.0;

#define SDA_PIN 1
#define SCL_PIN 18

void setup(void) 
{
Serial.begin(115200); 
Wire.begin(SDA_PIN, SCL_PIN);
ads.begin(0x48);
}

void loop(void) 
{
int16_t adc0;

adc0 = ads.readADC_SingleEnded(0);
Voltage = (adc0 * 0.1875)/1000;

Serial.print("AIN0: "); 
Serial.print(adc0);
Serial.print("\tVoltage: ");
Serial.println(Voltage, 7); 
Serial.println();

delay(1000);
}

This is the Serial output with me slowing moving the pedal connected through the TRS jack:

Not yet tested on T-Display-S3.
Try to change pin combination because GPIO_NUM_1 is used also for DIN_MIDI_IN.

I've changed the DIN_MIDI_IN to GPIO_17 which is empty at the moment....

I've tracked another couple of logs in the console now.
As soon I change the PEDAL 5 to ANALOG 4, I have these errors:

Can you give a try to latest version 3.4.1?

Yeah sure... meanwhile I was trying to debug the issue, I believe there is something in the refresh_analog4() that's not working....

Ok, now it's better!
I've noticed that because we would have 4 inputs, I should set the Control to Pedal 5 - Button 1, I've seen in the logs that 4 buttons are logged.
Now... It's better, I see the Control Change and the bar in the display, but at some point while I do up and down with the physical pedal, the board hangs and reboots. And also while it's in that state, it boot loops few times.

There's nothing useful in console.

We are getting there but there should be something else that is acting weird.

When in hang, meaning "if I move the pedal nothing happens in the display or console", If I don't touch anything and the board does not reboot by itself, it happen one time that it recovered and the I was able to use the pedal again.
It seems like i2c bus overload or something like that, or an electrical problem.
Should I try to pull-up the two GPIOs?

Ok I had the Activity Threshold and the Ease at the lowest level to test the inputs, it's definetly too much. Now I have Ease 2 Threshold 16, and it seems more stable. Now I don't have any jump in the values sent over MIDI!!!! It seems stable. I'll test it more and eventually I'll let you know, I need to restore the whole config now :)
This enhancement works like a charm with the analog input now!!! Thanks!

I'm having some weird behaviors when I enable ANALOG 4 in the web ui... I got a board reset but I can't trace anything in the console unfortunately :( As soon I click "Save" the board restarts. It happens especially when I set the ANALOG 4 on the Pedals of Profile B. Now also when I switch to Profile B with Analog 4 enables (miraculosly) the board restarts.

Also, when enabled, the WiFi started to acted strange and sometimes it doesn't connect properly
I got this in the console at some point:

[ 36737][W][WiFiGeneric.cpp:1061] _eventCallback(): Reason: 8 - ASSOC_LEAVE
SYSTEM_EVENT_STA_DISCONNECTED

The upcoming release 3.5.0 will fix the analog input for T-Display S3 board. It fixes pins assignment and a software bug.
