"Four wire" SPI and 8 bit parallel interfaces are supported. Direct Memory Access (DMA) can be used with the ESP32 and STM32 processors to improve rendering performance. The library can be loaded using the Arduino IDE's Library Manager.
#ARDUINO EMULATOR MAC TFT 32 BIT#
The library is targeted at 32 bit processors, it has been performance optimised for STM32, ESP8266 and ESP32 types. The dial rim and scale is a jpeg image, created using a paint program.Īn Arduino IDE compatible graphics and fonts library for 32 bit processors. To run this example the TFT must support reading from the screen RAM. See setup file "User_Setups/Setup35_ILI9341_STM32_Port_Bus.h".Ī new "Animated_dial" example has been added to show how dials can be created using a rotated Sprite for the needle. This gives a dramatic 8 times better rendering performance for the lower clock rate STM32 processors such as the STM32F103 "Blue Pill" or STM411 "Black Pill" since no time consuming data bit manipulation is required. The DMA Test examples now work on the ESP32 for SPI displays (excluding RPi type and ILI9488).Ī new option has been added for STM32 processors to optimise performance where Port A (or B) pins 0-7 are used for the 8 bit parallel interface data pins 0-7 to the TFT. The library now supports SPI DMA transfers for both ESP32 and STM32 processors. The interface is 8 bit parallel only as that controller does not support a SPI interface.Ī companion library U8g2_for_TFT_eSPI has been created to allow U8g2 library fonts to be used with TFT_eSPI. The library now supports SSD1963 based screen, this has been tested on a 480x800 screen with an ESP32.
The GUIslice library will make use of this feature to speed up the rendering of GUI objects ( see #769). The coordinate datum by default moves to the top left corner of the viewport, but can optionally remain at top left corner of TFT.
When a viewport is defined graphics will only appear within that window. See "Viewport_Demo" and "Viewport_graphicstest" examples. The library now provides a "viewport" capability. This operates in the same way as the TFT viewports, see 2. spr.setViewport(5, 5, 20, 20) so graphics can be restricted to a particular area of the sprite. Viewports can now be applied to sprites e.g. At the moment only SPI interface displays have been tested. The setup file "Setup60_RP2040_ILI9341.h" has been used for tests with an ILI9341 display. The library now supports the Raspberry Pi Pico with both the official Arduino board package and the one provided by Earle Philhower. Thanks! NewsĭMA can now be used with the Raspberry Pi Pico (RP2040) when used with 16 bit colour SPI displays such as the ILI9341. Use the "Issues" tab only for problems with the library. Comments in discussions tab (not issues at the moment please) are welcome.Ī new "Discussions" facility has been added for Q&A etc. A Beta test branch has been created, this has some new anti-aliased line functions (drawSpot, drawWideLine and drawWedgeLine), see the new Anti-aliased_Clock_v3 example.
