(一)前言: 驱动小外设模块,无非就是读写寄存器而已,但是接口可能是spi/i2c/uart/qspi/mcu等等。考虑到这种共识性, 本文将这些共性进行了抽象和归类,定义了一个通用的HwInit类,这个类接受一个command_list,并由外部定义和传递读/写函数,即可实现对外设的读写访问。这使得驱动各种电子模块,只输入输入一个command_li...

6.1.1 Version 1 All commands include a continuation bit C. This bit is also included in the byte used to set the DRAM address. If the continuation bit C = 1, the control bytes continue and the next byte will be a command too. If the continuation bit C = 0, the byte is the last...
These interfaces are used in general for the display initialization commands or for the touch panel control. Figure 13 shows a display panel connected to an STM32 MCU, using the LTDC interface signals illustrated in Table 5. Figure 13. LTDC signal interface STM32 HSYNC VSYNC DE PCLK RGB The...
