Help , display tempareture using lcd

[ecestar]

hi

i want to display tempareture using lcd and microcontroll i am finshed
convert this tempareture to frequancy to send it and then receive this frequancy and
each tempareture have one frequncy
the frequancy is the out put from the receiver to the microcontroll
now i want to show this result on the lcd

at example in 2khz input the output on the lcd is (25)
in 2.5khz input the output on the lcd is (30)

so i want code to make that using c language

the type of microcontroll is p89c668 (8051)
the type of lcd ( pc1602f)so i want help about that

Hello,

Thank you for reaching out for help with displaying temperature using an LCD and microcontroller. This is a common task in the field of electronics and can be easily accomplished with the right knowledge and tools.

Firstly, you will need to gather all the necessary components for this project, including the LCD (pc1602f) and the microcontroller (p89c668). You will also need a temperature sensor, such as a thermistor or a digital temperature sensor, to measure the temperature.

Next, you will need to write a code in C language for the microcontroller to read the temperature from the sensor and convert it into a frequency. This can be done by using a formula or lookup table to map the temperature values to corresponding frequencies.

Once you have the frequency value, you can send it to the LCD to display it. This can be done by using the appropriate pins on the microcontroller to communicate with the LCD. You will also need to write a code for the LCD to interpret the frequency value and display it in the desired format.

I would suggest researching and studying the datasheets of the microcontroller and LCD to understand their pin configurations and communication protocols. You can also refer to online tutorials and forums for guidance and support in writing the code.

I hope this helps and good luck with your project!
