The main goal of this tutorial is to show how to convert monochromatic bit map for HEX file and run by Attiny85 and OLED display SDD1306. Lego Harry Potter Years 1-4 Pc here. Due to running campaign for on Indiegogo I receive question how did I do graphics for SDD1306 OLED display. Instruction in pdf can be downloaded from web page. This tutorial will give expanation for this question. Step 1 - What do we need? Step 2 – Converting bitmap to HEX Step 3 - Run AVR Studio Step 4 – Preparing graphic file Step 5 - Pacman on the screen Step 6 - Extras. Depend on the AVR studio version GUI can be different.
Convert compatible images for emWin. LCD Bitmap Converter for emWin is an image converter tool, which helps you conveniently convert images into an emWin bitmap. Lcd-image-converter - Tool to create bitmaps and fonts for embedded applications, v.2. Windows 7 Ultimate 32 Bit 10mb Images on this page. DisplayModule's FREE Image Converter, will convert 24-bit bitmaps to 16-bit bitmaps (565, flipped row-order).
Currently I'm using Version 4.18 which is still OK for this purpose. Create new project Choose AVR Simulator and ATtiny85 Copy source from bitbucket.org to project folder (D: OLED_SSD1306 OLED_SSD1306) In AVR Studio mount corelated files First from subfolder called ssd1306xled_test load main.c Then from subfolder called ssd1306xled load num2str.c ssd1306xled.c and ssd1306xled8x16.c If everything was done properly all files should be in the Source Files Double click on main.c On the main window you will see source code of the main.c file Before we go further it is worth to check if source code can be compiled. To do this go to the top bar Build and run function Build On the bottom line of AVR Studio you will see statu after compilation. Green lights and 0 warnings – this is our goal. Now it is time for pacman file prepared in Step 2 Open pacman file with text editor. You will see char table with hexadecimal value. This is the representation of bitmap file.
Mark everyhthing from brackets and copy ( Ctrl+C) Now open folder D: OLED_SSD1306 OLED_SSD1306 ssd1306xled_test and open file called img0_128x64c1.h Structer of this file will be similar to pacman file. Roni Size Reprazent In The Mode Rar on this page. Delete everything inside a brakets.
And copy content by (Ctrl+V) from pacman file Save ( Ctrl+S) and close the file. Now go to AVR Studion and one more time Build and run function Build After succesful compilation in folder D: OLED_SSD1306 OLED_SSD1306 default we will find file called OLED_SSD1306.hex.
