M5Paper, using canvas in procedure
-
Have wrote a simple program, with a procedure that use canvas.
When compile the program get error message
"canvas1' was not declared in this scope" .This is my program:
#include <M5EPD.h>
void setup() {
M5.begin();
M5.TP.SetRotation(180);
M5.EPD.SetRotation(180);
M5.EPD.Clear(true);
canvas1.createCanvas(960, 540);
canvas1.loadFont("/fonts/GenSenRounded-R.ttf", SD);
DisplayDisplayWindSection(480, 270, 300, 3.5, 40)
canvas1.pushCanvas(0, 0, UPDATE_MODE_GL16);}
void loop() {
// put your main code here, to run repeatedly:}
void drawWindroos()
{
canvas1.loadFont("/fonts/GenSenRounded-R.ttf", SD);
canvas1.createRender(30);
canvas1.setTextSize(30);
}The error is shown in the first line of the procedure drawWindroos.
How to avoid this error?Cheers,

@powersoft
Do you only have 1 canvas? Trycanvas
instead ofcanvas1
.BTW, you can enclose your code in three back ticks (```) to make it easier for us to read, like this...
this text has three back ticks before and after it
