Hi,
http://learn.parallax.com/tutorials/language/blocklyprop/oled-display-blocklyprop/using-rgb-color-values

OLED draw rectangle at (X) 10
(y) 10
width 70
height 40
roundnes 0
color color valur from:

this block don't work,
I get the error message

Compile... Failed!

is it a library problem?
how do i insert them?

thank you and greetings

Welcome to the forum!
Are you using BlocklyProp or BlocklySolo? Are all you libraries up to date?
What board are you selecting?

borellogio

thanks for the welcome
I ams using Blocklyprop, board is Propeller activity board, original, not WX.
how do i know if the libraries are up to date?

Best regards.

Please do build the project on Solo. Solo has the latest libraries and a few new and updated blocks that will no longer work in BlocklyProp. If the project fails to compile on Solo, please post the project file and we will take a look.

I am having the same problem. I only use 'Solo'. I re-installed BlocklyProp Launcher (BPL) so I assume the libraries are up to date (no way of knowing as the BPL has no version shown). My OLED is working with other blocks. I tried a simple program as attached.

Basically, the 'color value from' block does not work since if I change it to a 'Color [x]' where [x] is a square of actual color, it works and draws a square of the selected [x] color.

The code is shown as being:

#include "simpletools.h"
#include "ssd1331.h"
#include "colormath.h"

Main Program

int main() {
oledc = ssd1331_init(17, 6, 5, 3, 2, 96, 64);
fillRect(oledc, 0, 0, 96, 63, remapColor(0x NaN, "8R8G8B", "5R6G5B"));
}


When I tried to compile it I get:

Compile... Failed!

It appears that the RemapColor block (color value from...) is not generating the correct C code. The problem is that the first argument is not evaluating correctly and is resolving to NaN (Not a Number). If you disable the block, the project compiles without error. I'll create an issue for this on GitHub.

#include "simpletools.h"
#include "ssd1331.h"
#include "colormath.h"

// ------ Global Variables and Objects ------
screen *oledc;// ------ Libraries and Definitions ------




// ------ Main Program ------
int main() {
  oledc = ssd1331_init(17, 6, 5, 3, 2, 96, 64);
  fillRect(oledc, 0, 0, 96, 63, remapColor(0x NaN, "8R8G8B", "5R6G5B"));
}
