Let's Control It

giorgino

Hi, I'm trying to drive a Nema17 step motor too.

Is there a final plugin built in actual release?

I've seen 48 79 98. Is it ok for using with A4988?
Thankyou

giorgino

Thanks for your observations. The pin zero with pull-up resistor was because sometimes when powering, the system wasn't booting, remaining with the red led. Here in the forum I got this suggestion, with capacitor too. The pinout of the devkit esp32-s3 is numbered as the drawing. In the software I've...

giorgino

The pins seems to be all free.
About the diodes... is not enough the internal structure of the ULM2003 ?

giorgino

Hi, (after many nights workin about it) this could be my final solution: - to limit the total energy consumption I've adopted bistable relais, so I need only the power to switch - (the bistable relais has two contacts, one for the load and the secodn to report the status of the switch back to esp32)...

giorgino

easyEDA, freeware, online, for me the best

It can solve the circuit drawing the PCB too

giorgino

ops sorry, mistake

giorgino

so this will be my schematic solution. What do you think?

and now I'm a little in trouble after reading this:
https://www.tarthorst.net/victron-ve-direct/

perhaps in "ESP32 side" It's better to connect the 3,3v instead of 5V, can someone check the value of the resistors?

giorgino

Scheme-it-export-Kim-ESP32-2024-11-16-08-25.png I'm new on ESP32. ESP32 has more hardware UART. The Victron plugin will run on multiple victron devices, on the same ESP32 board? Or will flood the CPU? Ath or TD-er will know how many serial devices the serial engine of ESPEasy can cope with but FWIW...

giorgino

the victron baudrate is 19200. Could it be a problem?

giorgino

yes I have more serial: gpio 16: victron MPTT gpio 17: victron BMV712 gpio 19: GPS neo the display NEXTION (tx and rx) arrive throw I2L software serial the two ground of the two victron-ve is connected at the general GND mmmh I think I got a mistake, in effect on my ESP32-S3 i have: HW SERIAL 0 HW ...

giorgino

yes I have more serial:
gpio 16: victron MPTT
gpio 17: victron BMV712
gpio 19: GPS neo
the display NEXTION (tx and rx) arrive throw I2L software serial

the two ground of the two victron-ve is connected at the general GND

giorgino

same baud rate, same configuration, one at interval 15, the other interval17 I have never connected the 5V of BMV (ad it's working from one year with two wires non shielded), I heard on some forum to leave it disconnected 100cm non shielded cable in a clean way (passing throw holes nearh 12V battery...

giorgino

today a new issue on my system: I've finally connected the second Victron device. After the connection the signals from the first stops working
Then no other signals (also from the first)

@affinite : do you connect only gnd and tx or +5v too?
I've only gnd and tx

giorgino

IT WORKS !
thanks

better (for me) going bed early tonight

giorgino

ops, sorry

Anyway, with 10k between gpio0 and gnd it's worst: never boot! pushing button the green blinks but remain off

Reset Pin
GPIO ← Switch:
- None -

is this ok?

giorgino

connected a capacitor 4.7uF (the lowest available in my lab) and seems work (first boot not, the other in short sequence everyone boots ok)
About the resistor between GPIO 0 and GND: I don't have any GPIO-0, I start from 1

giorgino

in effect sometimes when I connect 5v the green led lights on too, but sometimes no

giorgino

nothing: I connect different gnd too:
When powering I geto only red led lights on
then i press RST ( or BOOT) and green led lights on and espeasy goes online

Since i don't press the unit stay idle with red led waiting

giorgino

using the ESP32-s3 in the above pinout I guess if i could power it by two pin instead of USB connecor.
I try to connect 0 to gnd and 5v to "5v in" but the unit doesn't boot. It appen only if I press the RST button on the unit
How can I power (and boot) it without USB ?

giorgino

why do you exclude something more compact? relais could become eight... I've seen the ULN2003 or the TBD62083APG. Is there something better?

giorgino

Hi, in my project, I need to control at least four relays. Since I aim to keep the module compact, I am designing a custom PCB (EasyEDA seems to be a great platform for this). I’d like to avoid using any separate “Relay Module Development Board” by connecting the components directly on the board. Do...

giorgino

aaaah, I hadn't seen it before
thanks alot - as always

giorgino

Hi, my project is growing up, connecting more I/O but I'm not sure if I've got the right pins Can you look if I'm wrong? I have 8 GPIO: 1 - Victron VE (Battery monitor) -- HWserial 0 --- GPIO 38 2 - Vicron VE (Solar charger) -- HWserial 1 --- GPIO 13 3 - pulse counter --- GPIO 15 4 - DHT 22 --- GPIO...

giorgino

what about the 5V / 3,3V ?
Victrons, Nextion (and GPS too) are powered by 5V so I've passed their data TX/RX throw a step down voltage
What I have to do now?

giorgino

ok, it's arrived !

now I only need to learn how to use it

giorgino

now waiting for a (semi) final version with 176 plugin included

giorgino

gps#course IT WORKS !

giorgino

so you mean that I can use "rule1" only, with all the code there?
totally It will be 3500/4000 bytes long

giorgino

sorry, I'm a little confused... Is there any different dimension changing ESP32 model? (I'm starting with the ESP32-s3 16M) I mean if using a 16M there is bigger memory space for rules or not... is there the limitation of 2000bytes for every RULE ? I don't remember why have you built the rule1,rule2...

giorgino

yes, "course" seems to be the data I need... will it become available in a future edition of the plugin?

giorgino

yes, BeaRinG , direction

giorgino

thank you for explanation.
Is there an easy way to calculate BRG?
or I continue writing in rules a formula to calculate the azimuth between points

giorgino

please how can I obtain more GPS data exept the four selected values? Do I have to "send all togheter?"

giorgino

I'm sorry guys, no works onboard this weekend. I've got this screenshot in my first tries with the second version of the plugin, and some checksum error appeared.

if this could be useful to you.....

giorgino

Sure! I've tested the first release last weekend, with problem about my syntax coding rules
Next weekend I'll be onboard updating the code. I will solve every problem using the ESP32-S3

Very grateful to Ath and Tder for them work

giorgino

The deepsleep was the strong point of my project

But I've disabled the deepsleep in this weeks that I'm always connected working on the system

I the final version of my system there will be an input to wake in case of an alarm (I have a flooding switch sensor that activate the bilge pump)

giorgino

Sorry I've never used I2C converter Then having one of those I2C to serial converters is probably the best way to go. do you mean something like this? usb to serial.png On my ESP32-S3 board there is 2 usb connector, one called USB and one UART so one for the power and one fro the seriale (the third)...

giorgino

ok
I'm also testing my new ESP32-S3 with 16mBflash

Do you think it could be the best solution?

giorgino

as I said otherwhere the first rules of my project is to be low-low-low consuption because it live onboard, conneced to a service battery (recharged by solar power) but... consuption has to be the low as possible
So using other nodes is not a way I like

giorgino

In my project I need to connect many serial input: 1 - NEXTION display 2 - GPS 3 - VICTRON-ve (battery monitor) 4 - VICTRON-ve (MPTT solar charger) I'm testing the 4051 multiplexer and seems to work fine I plan to connect 1 to SWSERIAL With the 4051 I plan to connect the 2,3,4 to HWSERIAL1 then with...

giorgino

Already working !

giorgino

sorry that I can't test it now, the system is on my boat, far from here. I'll back onboard in 2 weeks. Now I can only try to collect the data publishes from the MQTT throw the controller, and place them on my portable dashboard (HA dasboard on smartphone) In the meantime I will continue my studies i...

giorgino

Well, it reveals that you haven't checked the "Single event with all values" checkbox, or there would have been a single line "EVENT: VictronBMW#All=12.81,0.84,99.70," in that log in this configuration I've removed that flag because I like to have single event for each value I w...

giorgino

ok now it works here the log: 7201724: P176 : Checksum state: 5 7201743: P176 : Processing data 'MON 0', checksum: 124 7201743: P176 : Checksum state: 5 7201765: P176 : Processing data 'Checksum ', checksum: 47 7227274: P176 : getReceivedValue Key:i, value:-840 7227274: P176 : getReceivedValue Key:s...

giorgino

ok the problem was the INTERVAL, now it works but I still got nothing publishing in the task, with or without the "send all togheter" on Victron#All Do Publish,'VvoltageV',[VictronBMW#V] Publish,'Wvoltageall',[VictronBMW#all] Endon on Clock#Time=All,**:** do // will run ogni minuto Publish...

giorgino

and this is some (testing) rules:

Code: Select all

on Victron#All Do
  Publish,'VictronBMW#V',[VictronBMW#V]
Endon

on Clock#Time=All,**:** do    // will run ogni minuto
  Publish,'VictronBMWvoltage',[VictronBMW#V]
  Publish,'WaterLevel',[DimmiWaterLevel#GetLevel] 
endon

giorgino

in the DEVICE summary screen there is:

V:0.00
I:0.00
SOC:0.00
ERR:0.00

but inside the DEVICE screen it is allright...

This is strange, do you?

note: with HWSERIAL 1 noting has change
