A replica of ST's SPI screen expansion board X-NUCLEO-GFX01M1. On the basis of ensuring compatibility with the original version, the screen is replaced with a more easily available 2.4-inch SPI interface TFT-LCD.
The X-NUCLEO-GFX01M1 expansion board adds graphical user interface (GUI) development capabilities to the STM32 Nucleo development board.
It has a 2.4 (official version is 2.2) inch SPI QVGA TFT display, and a 64mbit SPI NOR flash memory for storing graphic images, text and textures. The expansion board also provides a five-way switch for GUI navigation.
X-NUCLEO-GFX01M1 uses ST morpho connectors. It is compatible with Nucleo development boards in the following models: NUCLEO-F030R8, NUCLEO-F070RB, NUCLEO-F072RB, NUCLEO-F091RC, NUCLEO-F401RE, NUCLEO-F410RB, NUCLEO-F446RE, NUCLE O-G071RB, NUCLEO-L053R8, NUCLEO-L073RZ, NUCLEO-L412RB-P, NUCLEO-L433RC-P, NUCLEO-L452RE, NUCLEO-L452RE-P, NUCLEOL476RG
Because the 2x19Pin double-row female connector is not easy to purchase, the 2x20pin double-row female connector is used here. Please leave the 4 pins marked NC unconnected. Although the hardware of this project is compatible with the official version, in terms of software, ST's Demo relies on the TE signal of the display as the vertical synchronization signal, so when downloading the official code, you need to slightly modify the code: disable the TE signal or use a Timer sends TE signal at 60Hz frequency. (You can refer to the modified version of Demo provided in the attachment: GFX01M1_HelloWorld.zip
) If you need 100% perfect compatibility, you can go directly to the ST official website to download the Gerber file proofing of this project. It should be noted that the official display screen is DT022CTFT, and the price on Taobao is about 200 yuan.
