[SOLVED] MCP23017 Not working properly

[joneox]

I'm making a remote control for an rc car that I'm going to make. When it was on the breadboard, the MCP23017 was working fine, but now that I've soldered all together, the code stops here:

if (!mcp.begin_I2C(0x20, &I2C_1)) { // Inicializa com o endereço 0x20
    Serial.println("Erro ao iniciar MCP23017.");
    while (1); // Pare o programa se o MCP23017 não puder ser inicializado
}

Also is there a way to print the current mcp address?

Here's the full code:

How did you solder the address pins ?

[joneox]

I just added the diagram

[guix]

Did you check with multimeter if the address pins are correctly grounded, and there is no solder bridges anywhere ?

Try I2C scanner

Maybe the device was damaged during soldering

[joneox]

I don't know if this is normal, but on my two esp32s EVERY pin is "shorted". For example, if I put my multimeter on the continuity scale and then test GND and 3V3, they are shorted. But even so, both always worked well.

[jremington]

No, not normal. The continuity check is either not working correctly, or you are using it incorrectly. Make sure that the MCU is not powered when testing continuity.

[joneox]

@guix

Try I2C scanner

I tried one and it says this:

Scanning...
I2C device found at address 0x3C  !
done

.

@guix

Maybe the device was damaged during soldering

I changed the MCP and it still don't work

Also, I'm not using any resistors in SDA and SCL. Could this be the problem?
And if it is, which ones should I use?

UPDATE: Tried it one more time and it was working 'till I restarted the esp32... Don't know why. It's so strange, it works only when it wants

[TomGeorge]

Hi, @joneox

Can you please post some images of your project?

Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.

Not a Fritzy cut and paste image.
Sorry but your Fritzy makes no sense electrically.

Thanks.. Tom...

@guix

@joneox
He means the address pins on the MCP23017 not the ESP.

@joneox

I don't know if this is normal, but on my two esp32s EVERY pin is "shorted". For example, if I put my multimeter on the continuity scale and then test GND and 3V3, they are shorted.

Yes this is normal because the voltage out of the continuity tester sends out a small voltage and this breaks down the chip's static protection diodes so it looks like a short.

Try this experiment, using the continuity tester test an LED. You should see the LED light up very very dimly. If you do not see anything then swap the leads over. This illustrates how useless testing the continuity of a chip is.

[Willem43]

@joneox

Also, I'm not using any resistors in SDA and SCL. Could this be the problem?
And if it is, which ones should I use?

SDA and SCL are open collector drivers. You need pull-up resistors to ensure proper functioning. 4.7K or 5K to 3.3V is typical.

[PaulRB]

@joneox

When it was on the breadboard, the MCP23017 was working fine, but now that I've soldered all together, the code stops here:

No bypass capacitor for the MCP.

Sometimes the stray capacitance of a breadboard can be enough that the circuit works without a bypass cap. But every bare chip in your circuit needs one, 0.1uF as close as possible to the Vcc & Gnd pins of each chip.

It might not fix the problem, but you should always add bypass caps, and it's very simple, so not much point looking for other reasons until you have eliminated that one.

And here's the diagram:

Could be dangerous.

Do your 18650 cells have built-in over-discharge protection? Most to not. The ones that do have a metal strip running the length of the battery and are slightly longer than 65mm because of the tiny protection circuit board.

Without those, the batteries can be damaged, and then there is a risk of them exploding or catching fire when you recharge them.

The AMS1117-33 claims to be "low drop-out" but I would not describe them like that. There are much lower drop-out regulators available such as MCP1700 and HT7333. With AMS1117, the battery life will be shortened because of its higher voltage drop.

Your AMS1117 will probably not work reliably, or at all, because you haven't added the recommended smoothing capacitors on its input and output pins.

Your ESP board may already have an AMS1117 onboard anyway. I'm not sure why you connected an external one also. None of your other components appear to need high currents.

Why are you using NRF2401? It's range is similar to the ESP's WiFi. There is also ESPnow if you want to communicate between ESP boards without actually using WiFi.

First of all, thanks for all of you guys help

@TomGeorge

Can you please post some images of your project?

I know, it's a mess, and you can barely understand what's happening, but I ensure you that there's no wires shorted

@Grumpy_Mike

He means the address pins on the MCP23017 not the ESP.

I don't know if this is what you are asking for, but everything is on the image I uploaded in the first post

@Willem43

You need pull-up resistors to ensure proper functioning. 4.7K or 5K to 3.3V is typical.

Thanks!

@PaulRB

No bypass capacitor for the MCP.

I will search how to do this

@PaulRB

Your AMS1117 will probably not work reliably, or at all, because you haven't added the recommended smoothing capacitors on its input and output pins.

Actually, I forgot to add them on the schematics, but they're here. 100uf on the input and 10uf on the output

That white thing is hot glue to prevent shorting

@PaulRB

Your ESP board may already have an AMS1117 onboard

Yes, it has. But I couldn't find any information about it and I don't know how much mA it can provide

@PaulRB

Why are you using NRF2401?

It's because my rc car uses arduino

Hi, @joneox
It would have been better for you to use strip or Vero board for your project.

Can you please post a copy of your updated circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.

Thanks.. Tom...

@TomGeorge

Sorry but your Fritzy makes no sense electrically.

What do you mean

[ilguargua]

You are missing connection for the reset pin of MCP, have to stay high for working.

Ciao, Ale.

[joneox]

Thanks, solved my problem.

Thanks to everyone who helped me

[TomGeorge]

@joneox

What do you mean

The circled wire arrangements.
What wire goes to what terminal on the 1117 for example, what are the terminals named?
The MTS, two of them only have ONE connection and in all cases you have wires over top of other wires.
None of the 23017 pins is labelled.

Sorry but this would have been noticed earlier with a concise schematic.

My bad. It's because I made this scheme just for myself, I didn't plan on showing it to anyone else.

Unbelievable.

We can only know what you tell us and we didn't stand a chance did we?

For your information your whole circuit is riddled with errors you have been told about and done nothing to correct this. We can tell this from your actual photographs.

One wonders why you ask questions only to ignore answers.
