Zynq Design Example

DHT11 Interfacing Zynq PL.

DHT11 FPGA VHDL implementation

Tool Requirement

• Xilinx Vivado
• Xilinx SDK (for standalone software)
• Any C/C++ IDE for (Linux software)
• Linux kernel source

Hardware

• Connect DHT11 data pin to any pin of zynq device
• Create a Design in Vivado with zynq processor.
• Add local repo as ipblock folder
• Add DHT11 from ip catalog

Software

• Xilinx SDK for bare metal coding
• C/C++ using mmap to map physical address
• Kernel code with character driver / misc platform driver(my case)

NOTE

• To use kernel driver you need device tree which has to be included while building kernel.
• Please remember to change base address(AXI lite interface) according to your design.
