STM32F429 Chrom-ART™ Makes Eye-Catching Graphics Easy for MCU applications!
Article describes advantages and how it works with sample code to help you get started.
The STM32F429 integrated Chrom-ART Accelerator™ (DMA2D) allows easy integration of complex graphics in your MCU application without complicated code and without bogging down core processor performance. How...?
The DMA2D with the help of other STM32F429 peripherals (SDRAM and LCD controller) essentially calls bitmaps from memory (Flash, RAM, SDRAM) and displays them directly to your LCD. More importantly, the DMA2D can manage the merging of multiple bitmaps on the LCD while respecting their position, layering and transparence.
Francis Lamotte describes how this is done in this informative and complete article at Embedded.Com. He provides simple explanations for how the DMA2D works with samples from the code that is available in the STM32F429 EvoPrimer example sources.
Standalone Programming with EvoPrimer & Open4
An upgrade to "LAB" capability is now available that allows users to program STM32 microcontrollers in standalone operation using their EvoPrimer or Open4 base. In addition, users can monitor application variables and addresses while the application executes using the tool's monitoring capabilities.
Upgrades include all necessary connection accessroies, SD card and firmware upgrade to support standalone programming and monitoring features.
Note: The ST EvoPrimer products are derivative products of the Raisonance Open4. The same Primer Target Boards, extension boards, software tools and sample applications are used with both EvoPrimer and other Open4 derived products. Open4 is a versatile tool platform that allows a wide range of derived primer and other tool products.
