Abstract: This application note discusses techniques to connect Maxim's daisy-chained SPI™-compatible display drivers and GPIO to 3-state SPI devices. This application note discusses techniques to connect Maxim's SPI™-compatible display drivers to other SPI devices on a common SPI interface. T...
Example https://github.com/Bodmer/TFT_eSPI/tree/master/examples/Generic/ESP32_SDcard_jpeg with SD not working with Esp32 S3 because TFT uses HSPI and SD lib not. So the SPI bus brakes when using both TFT and SD. Solution Platform esp32:e...
The communication interfaces can include General Purpose Input/Output (GPIO), parallel ports, and serial communication interfaces. Some of the typical serial communication interfaces supported in microcontrollers include UART, USART, I2C, SPI, 1-Wire, Microwire, USB, and others. The microcontrollers als...

Although 8051-compatible microcontrollers with SPI ports are available, a lower cost device with an SPI port bit-banged through GPIO pins often suffices for many applications. The code shown here takes advantage of features specific to the 8051 core to create a fast SPI port with minimal effort...

下面举例gpio DM驱动模型来介绍它们之间的联系,如下: 在uboot全局变量中保存了gd->uclass_root,它就是uclass的head。我们可以通过成员struct list_head sibling_node遍历整个uclass list,然后找到想要的uclass。它们之间的关系如下: 在uboot命令里面有一个dm命令,可以打印整个DM驱动模型tree,可以帮助我们更好的理解DM。

10.1.2 GPIO Ports for Communication Most microcontrollers have programmable input/output (I/O) pins that can be set in software to act as inputs or outputs. If an SPI controller is not available, the ADS1118 can be connected to GPIO pins and the SPI bus protocol can be simulated. Using...
