Want to write a formaldehyde detection based on the microcontroller program, requirements to fixed value will call the police, can record test data and flip for many times, with lcc1602
Please everyone a great god help!!!!!!!!!!

CodePudding user response:

With what kind of data transmission, block a EEPROM program, a display program, you one by one

CodePudding user response:

EEPROM and LCD, you next document, formaldehyde detection sensor data lines connected to the circuit boards, according to the agreement to read it

CodePudding user response:

Mainly is the single chip microcomputer is partial, can't write it's built-in AD converter,

CodePudding user response:

The MCU AD version, specific and didn't try, you can consult STC51 AD program, check the DataSheet

STC51 microcontroller is not wide, general 889 c52 is ok, on the other hand, in a variety of specifications for example should say is quite comprehensive, direct copy can be used, including some set tools like website, 1206 driver search on the net, a lot of, can use directly, E2ROM drive is very much also, down can be used directly,
