This function is also normal when tested on stm32f407 board

The font files are stored in sdcard

The display speed is much faster than that of esp32

Rgb565 mode can support 128 × 160

The 16 color mode can support 320 × 240

Firmware feature update By adding 4-bit look-up table conversion function, TFT can be driven by 4-bit FB The background color of character display is added. When the background color is 0, it remains transparent Fixed RGB24 BMP display color error Demo added ST7567 monochrome LCD module 128x64 ， esp...

The Chinese font library is downloaded from the file system. Without using Chinese, you can also get large English fonts, enlarge, rotate, and reverse

I don't know the rules of open source very well. I'm willing to share the code that needs to be modified The Chinese font library comes from the font library of windows system. It is captured after displaying the screen picture. It is not confirmed whether there is copyright conflict Because most of...

Modify framebuf.c implementation

In addition to Chinese support, it also provides FB large character display, 8 megabyte / 16 megabyte flash precompile, and BMP file display and storage

https://github.com/wangshujun-tj/mpy-Framebuf-boost Precompiled 1.13 firmware, support the combination of spiram and 4 / 8 / 16 MB flash, 6 versions Provide GB2312 and GBK complete font library, with 12 / 16 / 24 / 32 four choices, the number in the file name represents the largest font, will also c...

I use the method of modifying partitions files to recompile the firmware and get the firmware that is suitable for 16 megabytes. I actually store and test more than 8 mega bytes of files and confirm that they are normal

can you help me? use command: make -j3 BOARD=GENERIC_SPIRAM USER_C_MODULES=../../../micropython-ulab all output: CC ../../../micropython-ulab/code/scipy/optimize/optimize.c CC ../../../micropython-ulab/code/scipy/signal/signal.c CC ../../../micropython-ulab/code/scipy/special/special.c ../../../micr...

Can the DMA double buffer non-blocking mode be achieved? Unfortunately, it is not possible to reliably collect real-world continuous data

I have also encountered similar problems, which can be solved in the following ways through exploration. 1. Directly define other UART ports to overwrite repl on gpio1 and gpio3, but it will cause complete failure of repl, including ctrl-c. if the automatic operation of main.py is set, the board can...
