Application background 2015 issue of the source code, after detailed notes, it is easy to understand. Source implementation is as follows:AD part: the P1.0 (CN1 5) and P1.1 (CN1 6) is given to the test voltage (partial pressure not more than 5V), the conversion is displayed on the 12864 LCD screen;DA part: to pass a parameter to the out, the DATE_IN port output corresponding voltage (up) and current (down), and through the key control voltage, current increase. Key Technology Stc15c5a60s2 microcontroller, AD module for the stc15c5a60s2 microcontroller AD conversion, DA module for the tlv5616 chip, LCD display is 12864. Including serial port, AD conversion, DA conversion and other technologies.
