![]() ![]() DMA with 16-bit transfers is also supported. ![]() The use of the RP2040 PIO makes it easy to change the write cycle timing for different displays. This has been tested and the screen update performance is very good (4ms to clear 320 x 480 screen with HC8357C). Support has been added in v2.4.70 for the RP2040 with 16-bit parallel displays. These examples require a new support library here: New GUI examples have been added for sliders, buttons, graphs and meters. Here is a demo screen where a single 12kbyte font file binary was used to render fully anti-aliased glyphs of gradually increasing size on a 320x480 TFT screen: I have added TFT_eSPI specific examples to the OpenFontRender library and tested on RP2040 and ESP32 processors, the ESP8266 does not have sufficient RAM due to the glyph render complexity. Left, middle and right justified text can also be printed to the screen. The library provides access to compact font files, with fully scaleable anti-aliased glyphs. Here the smooth arcs have been used to create anti-aliased meter gauges on a 320x240 TFT:Īn excellent new compatible library is available which can render TrueType fonts on a TFT screen (or into a sprite). Here are two demo images, on the left smooth (anti-aliased) arcs with rounded ends, the image to the right is the same resolution (grabbed from the same 240x240 TFT) with the smoothing diasbled (no anti-aliasing): The arc drawing algorithm uses an optimised fixed point sqrt() function to improve performance on processors that do not have a hardware Floating Point Unit (e.g. Arcs can be drawn with or without anti-aliasing (which will then render faster). New sketches are provided in the "Smooth Graphics" examples folder. New functions have been added to draw smooth (antialiased) arcs, circles, and rounded rectangle outlines. The "RPi" interface style boards are now supported with the ESP32 S3. New board setup files have been added for the Seeed XIAO with round display, LilyGo T-Embed S3, LilyGo_T_QT_Pro_S3, ESP32 S3 Box and ESP32_S3_Box_Lite. ![]() The automatic opening of the font folder can also be disabled within the Processing sketch. The Create_font Processing sketch has been updated to automatically create a complete C header file. Use the "Issues" tab only for problems with the library. More about this board, including a full datasheet, Gerber files, schematics, and other files are available from the Nucleo Resource Page.A "Discussions" facility has been added for Q&A etc. In the end, you can pick from a wide variety of IDEs. However, if you feel more comfortable with the Arduino IDE, that could be your best option. While the Cube IDE may be a bit bulkier than its Mbed counterpart, I find that the number of time-saving features built into it are worth the installation.Įven with a plethora of libraries available, a graphical interface that assigns pins their different functions, and the fact that Cube is built upon the popular Eclipse IDE all improving the development process, the automatically generated code is what ultimately led to my decision of downloading and installing STM32CubeIDE. It is great for quickly prototyping ideas, or modifying existing projects on the go. The Mbed IDE is easy to use, simple, and available online. ![]() It can, of course, be programmed with Mbed’s IDE which is similar to the Arduino IDE, or from the STM32CubeIDE. Once the correct drivers are installed, the Nucleo shows up as an Mbed board since it is Arm Mbed Enabled compliant. It also features ST morpho headers for STMicroelectronics’s own expansion boards. The STM32 Nucleo board shares its pinout with the Arduino Uno, making it compatible with Arduino Uno shields. Even if removed, it retains the ability to program the main board if reconnected with jumper wires between CN4 and the corresponding SWD signals available on the ST morpho connector. ST-LINKĪll Nucleo-64 boards, including the Nucleo-L476, employ their integrated ST-LINK/V2-1 debugger as removable mini-boards. It is designed for IoT projects that require more I/O pins and a 32-bit processor for data acquisition. This board’s MCU the STM32L4 is one of the ultra-low-power microcontrollers offered by STMicroelectronics featuring a Cortex-M4 processor with a speed of 80MHz and a flash of 1MB. ![]()
