How to use cpld to drive ds18b20 to measure temperature and store the read temperature data in the register of cpld?

18B20 is quite simple. I don't know much about CPLD and have never used it.

If you want to ask about the code, you can go to ChatGPT and ask, and the code will be written for you.

The cpld drives the ds18b20 to measure the temperature. For relevant information about the ds18b20, please refer to the manual. Add a readable and writable register to the CLPD, and implement it by operating the read enable, write enable, address and data bus.

When I ask specific questions, I immediately don't know how to answer them. I used to look at the board and read the materials but still didn't understand anything.

Hi, is it possible to measure the temperature data of multiple temperature sensors and store each temperature data in its own separate register?

What if it's FPGA, sir?

I remember that 18B20 has an address, which can be used to distinguish multiple sensors. It is easy to download the manual. I haven't used it for a long time.

18B20 can be read as long as the logic matches.
