  converting with gd2asset
Posted by:  jblazeg - 20-11-2017, 23:33 15 - Forum: Herramientas para pantallas - No Replies

hello,

i tried to convert graphics with gd2asset but with no luck. The screen stays dark after uploading.

Even a already converted asset which seem to work elsewhere keeps the screen dark (see attachment). WHat am I doing wrong? I tried to convert with gd2asset and gd3asset - no change. After gd2 conbversion i get no error - just the normal "Assets report"

Cheers
Hendrik

attached is the jpg-file. converted gd2 is here: http://hsitc.de/t/heise.gd2

header:

Code:
#define LOAD_ASSETS()  GD.load("heise.gd2");
#define HEISE_HANDLE 0
#define HEISE_WIDTH 46
#define HEISE_HEIGHT 43
#define HEISE_CELLS 1
#define ASSETS_END 3956UL
static const shape_t HEISE_SHAPE = {0, 46, 43, 0};

ino:
Code:
#include <EEPROM.h>
#include <SPI.h>
#include <GD2.h>

#include "heise.h"

const unsigned int LOGO_TAG = 42;

unsigned int logo_x;
unsigned int logo_y;

void setup() {
 GD.begin();
 LOAD_ASSETS();
 set_logo_position();
}

void loop() {
 GD.ClearColorRGB(0xffffff);
 GD.Clear();
 
 GD.Begin(BITMAPS);
 GD.Tag(LOGO_TAG);
 GD.Vertex2ii(logo_x, logo_y, HEISE_HANDLE, 0);
 
 GD.ColorRGB(0x444444);
 GD.cmd_text(240, 136, 30, OPT_CENTER, "c't Hardware Hacks");
 
 GD.get_inputs();
 if (GD.inputs.tag == LOGO_TAG)
   set_logo_position();
 
 GD.swap();
}

void set_logo_position() {
 logo_x = GD.random(480 - HEISE_WIDTH);
 logo_y = GD.random(272 - HEISE_HEIGHT);
}

  Como usar BUS I2C2
Posted by:  lightcalamar - 12-11-2017, 14:20 45 - Forum: STM32 - Replies (7)

Estoy usando mi placa STM32F407VET6 y necesito conectar un modulo con bus I2C, pero lo deseo poner en I2C2 por el problema de tolerancias.

En el I2C1 la lógica es a 3,3 voltios, como por ejemplo, modulo radio, memoria 24C32 etc y en el I2C2 quiero poner un LCD alfanumerico tipo 20x4 estoy usando la librería que modifique para STM32 concretamente esta; https://github.com/lightcalamar/LiquidCrystal_I2C_STM32

Pues no me funciona en el bus I2C2 siendo :

  • SDA = PB11
  • SCL = PB10
Alguna idea?, es un problema de la librería?

  Scissor for Poly
Posted by:  jblazeg - 26-10-2017, 15:55 18 - Forum: Programación graficos por computadora - Replies (2)

Hope it's ok when I use English because I'm German and I do not have that much space lef tin my brain for another foreign language ;-)

I'm using Poly to draw a certain graphic, but now I want to use Scissor to restrict the painting area. It's not working because "Poly" uses Scissor itself. Any ideas how to move forward?
