8/19/2023 0 Comments Photoartist program![]() It is theoretically supported on multiple platforms, and related environments should be set up by users themselves. The program is written based on the C++ SDK of Rpi Pico and compiled using CMAKE.Note: This program is open source and does not come with technical support (bugs are welcome to be reported).Note: this open-source demo is only for users to develop, and we do not provide technical support for it.How to use: directly drag the picture to "convert.exe" for single picture conversion, or you can put all the pictures in the file folder and double click "converterTo7color_all.cmd" to convert in batch.The program converts images to the right resolution and optimizes them with the dithering algorithm, supports most formats, recognizes the orientation of images, and automatically stretches and crops them.Convert images using tools we have written, application, and source code for: 7 Colors Dithering Pictures Convertor.To create a scatter plot using tools such as PS, please refer to: E-Paper Floyd-Steinberg.Note: If you want to use the AUTO mode, you can install the button cells on the RTC chip or use a USB interface to power on. Finally, power on the PhotoPainter, you can choose the 5V Type-C USB interface or the 4.2V Lithium battery to power on.Next, insert the memory card into PhotoPainter, and note that the power supply should be cut off.(Note that the length of the file name is less than 100 characters and the file number is less than 100.) Then, please prepare a memory card in FAT32 format, and create a "pic" file folder in the root directory of the memory card.In addition, here are some sample images that show good results. Please refer to the next section for #Picture Production. The PhotoPainter only supports images in 24-bit BMP format, and the resolution must be either 480*800 or 800*480. Firstly, you need to prepare the picture to display.PWR indicator: each time before refreshing, the self-test will flash five times if the power is low it will light up during lithium battery charging and turn off after being fully charged.ACT indicator: each time before refreshing, it will flash three times if the self-test is normal it will flash rapidly when reading or writing to a memory card.Please note that the NEXT button is still active in AUTO mode. The trigger interval can be modified in the program and is 12 hours by default. In AUTO mode, the RTC signal triggers the picture switching. If you want to switch to the AUTO mode, you can turn it to "ON". AUTO-NEXT switch: this switch is for switching the operating mode of the PhotoPainter, the default setting is "OFF" and the RTC signal will not be processed. ![]() Please note that if the name or the total number of the pictures on the memory card changes, it will re-create the new index and play from the first picture. NEXT button: this button is for switching pictures, and the screen switches to the next picture after pressing it.
