I think ( but i am a noob) that the location of your libraries are not right.
Got multiple versions of the arduino ide installed ?
C:\arduino-1.8.7\libraries\WiFi
C:\arduino-1.8.7\hardware\espressif\esp32\libraries\WiFi
C:\arduino-1.8.7\portable\sketchbook\libraries\M5ez\
My best guess is to clean up other versions..... or update all versions on your system to m5ez 2.01
Having fun with m5ez
Now i am a copy and paste my own code .... coder....
Copied my slider and made a mechanism that selects and sets each slider.
Next and previous makes you jump between each slider, left and right sets the value , ok publishes the value and up gets you back to the main menu.
I still have issues to get my values in to m5ez object like the header, text works fine but int is still a issue. Tried to convert them to chars, but failed....
So much to learn at once.
Okay, i am going to try, as i want a value above my slider :O)
Thanks !
Is the hello world text replaceable with a variable ?
You could also add just an image to your mez screen.like this. But it has to be on a sd card.
M5.Lcd.drawJpgFile(SD, "/c50x50_light_icon_off.jpg",20, 75, 50, 50);
Below is my experiment to make my own dynamic slider to get familiar with the arduino ide and m5ez
The end goal is to read the value from mqtt and set the slider to the known value of the dimmer and set it
int bar_position = 25 ; // START POSTITION ( TO DO : READ THIS VALUE FROM MQTT AND SET IT )
Drop the line above in top of the m5ez to set the start position of the bar. Paste the below code in de the m5ez demo add to the main menu.
void menu_brightness_slider(){
int Bar_step_amount = 10; // bar is devided in XX steps ( for on/of set to 1 )
int Bar_lenght = 275; // Length of the slider bar
int Bar_height = 28; // Height of the slider bar
int Bar_steps = Bar_lenght / Bar_step_amount;
int Top_hLine_Start_X = 22; // X postion on screen from the left side
int Top_hLine_Start_Y = 150; // Y-postition on screen from the top
int Top_hLine_End_X = Bar_lenght + Top_hLine_Start_X ; // X End line postion on screen from the left side
int Top_hLine_End_Y = Top_hLine_Start_Y;
int Bot_hLine_Start_X = Top_hLine_Start_X;
int Bot_hLine_Start_Y = Top_hLine_Start_Y + Bar_height ;
int Bot_hLine_End_X = Top_hLine_Start_X + Bar_lenght ;
int Bot_hLine_End_Y = Bar_height + Top_hLine_End_Y ;
int Start_Point = Top_hLine_Start_X;
int End_Point = Top_hLine_Start_X + Bar_lenght;
int But_Radius = 10; // size of the slider indicator
int mid_button = Top_hLine_Start_Y + ( Bar_height/2 );
int bar_start_position = Top_hLine_Start_X + ( But_Radius ) ;
int bar_end_position = Top_hLine_End_X - ( But_Radius ) ;

// Prepare a JSON payload string
String payload = "";
payload += "{";
payload += "\"command\": \"switchlight\", \"idx\": 143, \"switchcmd\": \"Set Level\", \"level\":";
payload += dimmer_value;
payload += "}";
// Send payload
char attributes[100];
payload.toCharArray( attributes, 100 );
client.publish( "domoticz/in", attributes );

menu_brightness_slider();// Loop and restart slider
}
Not as dynamic as i wished, but its a start and with some parameter adjustments the slider bar can be converted to any size and even one that looks like a on and off switch, with only 2 positions.
Why not just draw a rectangle instead of 4 lines ? Well the lines could be replaced by bitmaps, so the slider button will run between bitmaps instead of over ( stacked bitmaps give me a kind of interlaced images and looks odd )
in this example i convert the slider bar to a scale of 0 - 100 and post in to my domoticz setup thru mqtt ( json formated )
The mqtt part of the code is missing, but thats nothing more than adding the library in the arduino ide and set the parameters.
Next step will be separate the mqtt part and run that on a different core, so connection won't stall over time.
void menu_brightness_slider(){
ezProgressBar bl ("Keukenlamp dimmer", "Set brightness", "left#off#ok#up#right#on");
while (true) {
String b = ez.buttons.poll();
if (b == "right" && brightness <= 90) brightness += 10;
if (!brightness) brightness = 100;
if (b == "left" && brightness > 11) brightness -= 10;
if (b == "left" && brightness < 11) brightness = 0.01;
bl.value((float)(brightness));
if (b == "ok") break;
if (b == "off")brightness = 0.01;
if (b == "on")brightness = 100;
if (b == "up") loop();
}
// Prepare a JSON payload string
String payload = "";
payload += "{";
payload += "\"command\": \"switchlight\", \"idx\": 143, \"switchcmd\": \"Set Level\", \"level\":";
payload += brightness;
payload += "}";
// Send payload
char attributes[100];
payload.toCharArray( attributes, 100 );
client.publish( "domoticz/in", attributes );
Serial.println( attributes );
menu_brightness_slider();
}
This works ! :O)
Now a long press set on or off or back to menu
Hey Rop,
I agree, and what you see is just a image from my design program. To get a estimate on how it looks in total on the m5. In the working model i use your header and buttons.
i did just adjust the dark theme a bit and in between my image shows.
Just playing with your work and see where the limits are. So far my programming is what limits me.
Stuck on how to get the _brigtness value into my mqtt.
Tried almost everything i can think of, did look into other code
did look how variables are used, but this syntax is over my head. This publishes _Brightness as text but not as value.
So close and still far away... It frustrates me over the past 2 days now.
client.publish("domoticz/in", "{"command": "switchlight", "idx": 143, "switchcmd": "Set Level", "level": _brightness; }");
It's just the basic skills i am missing, but in general i can understand what is happening.
I agree on usability like in rgbw, but left or right and next option will set the previous isnt that hard. Less pushes makes things more use able, thats something that is my experience.
a double push to go a level up/cancel might be more easy to understand for end users of the interface. While a enter or a level down is a single push of the middle button.
Again, thanks for all your hard work ! and i do hope that the community contributes a bit more as in sharing experiences and code. So we dont expect 3.0 but there is still hope for v2.99 ;o)
cheers
Robin
Happy with v2.0
The slider works fine now !
While looking into your code to find the brightness slider i realized you did a shit load of work in a short period ... Amazing!
Big thank you!
Also made one based on the image menu and let the slider jump in steps of 20 and simply change the image
Still having a hard time with the programming, but slowly i am getting some where.
Everything you see is just work in progress and hand drawn in vectors( sunday morning frustrations ). Ill make a bundle with stuffbut sofar its just all in one screen and vector. Would be great to make it a community effort and make it into a demo file that is included with M5ez.
Not sure about what the end point is, can we scale sliders. re position them.
I did re use most of my old gfx for a ipad interface
and that is downloadable here
This is spinning in my head... next to this dual core thingy. I guess this is what you get when i get frustrated from programming... lol
Its all yours..... Adjustments is no problem, its all vector gfx.
You can drop me a line at my hotmail.com account for the changes, just add my forum nick in front.
Cheers
Hey Rop,
Nice you are making progress!
I would like to see if i can move the slider in a negative way, not sure if i am much of a help with my skills.
But thats all up to you. Happy with all your efforts anyway.
Meanwhile i spend some time on doing what is more familiar to me.
Hi @ Moelski
@bobolink
yeah, i did find the guy with the funny accent ;o) video including the skeleton file.. thanks for the link!
I totaly agree! It might not be made with the intention to be remote controller, but it could be a nice one.
Not sure about battery life, but there is still much to gain on that subject i guess. Screen brightness for instance will help a lot.
I guess there are also a lot of things you could hook up on to the slider
Like a dimmer, volume controller or even stuff like tv channels, Where a double press could be 10 up or 10 channels down. where a short press is just one.
Or in a horizontal menu indicating where you are.
Not sure if the ezslider bar could be re positioned or combined with a image, but i guess we will find a way.....
Still wondering how i could do a rgb device in a easy way besides giving every color its own page.
:O)
Thanks bobolink, i will find some lessons about using the 2 cores of the esp32.
Cheers!
Thats good to know, so it could be that it isnt me... Learned a lot the past days! Thanks
Still have some issues on loosing connection over time, but not sure if that is me or the m5stack. Am i the only one ?
PS: backlight dimming would be nice on a ProgressBar, if it isnt to much work.
Okay i can get some value in to pb now and raise it once with + 10 by pushing a button and then i stall.
void add(){
ezProgressBar pb ("Dimmer", "Dims te kitchen light", "LEFT#UP#RIGHT");
pb.value(val);
while (val <= 101 && val >= 1 ) {
String btnpressed = ez.getButtons();
if (btnpressed == "UP") loop();
if (btnpressed == "LEFT") {
pb.value(val - 10);}
if (btnpressed == "RIGHT") {
pb.value(val + 10);
}
}
}
but i am not giving in until i got this running.
Any one that can give this noob some pointers ? It doesn't have to be a fixed solution but after some days of learning i am kind of blinded
I am failing hard on the progressbar, is there any other pointer or example people could share.
I have been reading for a few days, but i just dont get it.
I am not sure about pb.value(float val)
i want to add or distract 10 on a button push, but i am failing hard.
if (btnpressed == "up")
break;
else (btnpressed == "left"); {
pb = pb + 10; ;
}
if (btnpressed == "right"); {
pb = pb + 10;
}
Would be nice to abuse the progressbar for things like volume or dimmer status and if any one has a pointer. thanks in advance.
Hi Rop,
I finaly found some time and as non programmer i did manage to use your code and make it talk mqtt just copy and pasted some code from you and the pubsub lib and it does work.
Below the code i used to control my domoticz setup thru mqtt :
I had to make some adjustment to PubSubClient.h and made some values higher like socket timeout, max packet size and degraded version.
So i guess it isnt that hard after all. To make sure you understand that i am a compete noob and dont even know what language i have been copy and pasting.
Next try will be to use the ezProgressBar and let that drive the dimmer based on pb.value. But that will be a real challenge for me as copy and paste coder.
adjustment to PubSubClient.h:
#define MQTT_SOCKET_TIMEOUT 60
#define MQTT_MAX_PACKET_SIZE 1024
#define MQTT_VERSION_3_1 3
Now the code below runs fine sofar ( 15 mins or so )
#include <M5Stack.h>
#include <M5ez.h>
#include <WiFi.h>
#include <PubSubClient.h>
const char* ssid = "xxxxxx";
const char* password = "xxxxxxxxxxx";
const char* mqttServer = "xxxxxxxxxxxxxx";
const int mqttPort = 1883;
const char* mqttUser = "xxxxxxxxxxxxxxxxt";
const char* mqttPassword = "xxxxxxxxxxxxxx";
WiFiClient esp32Client;
PubSubClient client(esp32Client);
