@r_255
Dont know, you would have to ask rop but you can directly print the variable with one of the m5's lcd print commands. -
I did try it, but failed hard...
thanks ! -

thanks !What code are you using?
-
Any string that is supplied to any of M5ez's functions can also be a String variable.
So:
#include <M5ez.h> void setup() { ez.begin(); } void loop() { String header = "Hello World !"; ez.msgBox("M5ez minimal program", header, "Settings"); ez.settings.menu(); }
works as well as the version further above...

Okay, i am going to try, as i want a value above my slider :O)
Thanks ! -
@Rop I can't get my example to work, can you help?
I'm trying to use this image file
hello.h file hosted on github.But when I compile and upload, the image doesn't show. Can you see what i'm doing wrong?
This is my code:#include <M5ez.h>
#include "hello.h"
void setup() {
ez.begin();
ez.header.show("Hello World");
}
void loop() {
ezMenu images;
images.imgBackground(TFT_BLACK);
images.imgFromTop(40);
images.imgCaptionColor(TFT_WHITE);
images.addItem(hello_jpg, "Hello World");
images.run();
} -
@ajb2k3 If I try your hello.h, it doesn't compile because of double commas that I had to take out first. After doing that, it doesn't display an image indeed. But your image also doesn't display if I do
m5.lcd.drawJpg((uint8_t *)hello_jpg, sizeof(hello_jpg)); delay(2000);
In the
setup()
function. I don;t have the source JPG, but for now I'm assuming your JPG may be in a format that the M5Stack JPG library doesn't display, or something else is wrong with it.Also: if you want the menu to have a header, you should add it in the declaration of the menu:
ezMenu images ("Hello World!");
The menu clears the screen before displaying anything when you run it. You'll rarely need to use
ez.header.show
if you use standard M5ez functionality. -

Interesting /\ the forum isn't showing the image above.
I think it may be the conversion to array that is causing issues. I had this before but can't remember how I solved it. I also needed to check that it wasn't just my code that was at fault (excluding the hello.h)I left the header clear to give more screen room.
-
@ajb2k3 is this issue solved yet? I am also having difficulty adding image even using SPIFFS by imageSPIFFS example.
-
@orthodudz I worked it out now and currently writing up how for my handbook project.
I have managed to get an image to load without m5ez using UIFlow but you will need to see the face book group for the progress.
