13- SD Card Programming on STM32F7 Discovery Board using Keil uVision

توضیحات:

Create a project in Keil uvision for micro SD card interfacing on ST STM32F746 Discovery Board. 32GB uSD (micro SD ) card has been used with 1-Bit SDIO (SD Host) mode to create the project. I have created this code by using ST STM32CubeMx for Keil uvision v5. STM32F7 Board has one user led and 2 push button. It supports Arduino morpho connector as well as parallel camera and sd card interface. In addition to this, STM32F7 supports floating point hardware on the chip and it is running at the maximum speed of 216MHz. It supports ethernet as well as audio in and out. NVIC interrupt is closely coupled with the core to reduce interrupt latency. It supports 1-240 external interrupt with dynamic prioritization. It has three ADC with multiple channel and resolution of each ADC is 12 bit but resolution can be set the minimum as 6 bit. The board does not support DAC however processor has DAC on the chip. It has dual ALU to support higher processing rate with 64-bit prefetch unit. Board also support other general-purpose microcontroller function such as UART, USART, Timer, SPI, I2C, JTAG, Camera, SD Host, DMA and much more...
The STM32F746G-DISCO discovery board (32F746GDISCOVERY) is a complete demonstration and development platform for STMicroelectronics ARM® Cortex®-M7 core-based STM32F746NGH6 microcontroller.
