  1. Hello, I have some troubles with displaying BMP monochrome picture on display. I use the ugfx library with the 128*64 display (ssd1306 controller) and STM32F103CBT6; FreeRTOS uses HEAP4 memory manager. uGFX starts working in a dedicated task (uGFX init) and LOGOis displayed. In process task I try to drawing image (BMP 24*24 pixels). void displayPainter::vPrintScreen(uint32_t numScreen, screenPayload_t& data) { switch (numScreen) { case 0: { static gdispImage myImage; gdispImageOpenFile(&myImage, "gasoline.bmp"); gdispImageDraw(&myImage, 0, 0, myImage.width, myImage.height, 0, 0); gdispImageClose(&myImage); } break; case 1:// Gazoline for station in km break; case 2:// Error menu enter break; case 3://Error entity break; case 4://Eraze error break; case 5://No eraze error break; default: //Startup LOGO and TEST break; }; } But code breaks into the HardFault Handler in gdispImageOpenFile() function (in allocating memory procedure for priv->palette value). This error occures with images, strings and LOGO are drawn correctly. I tryed to insert Image drawing code to uGFX initialization task. Same error occured. What's the matter? What am I doing wrong? Thanks in advance/
