Product Description
Instructions for use:
1) Wide voltage (3V-5V) power supply. The chip is X9C103S; PCB board size: 2.7*1.3CM
2) 10K full-scale potentiometer.
3) The middle tap of the potentiometer slides between 0-10k for a total of 100 levels (the typical impedance of the potentiometer sliding end is 40 ohms)
4) The VL and VH ports of the digital potentiometer correspond to the low and high ends of the sliding rheostat respectively, and the input voltage range is allowed to be -5V to +5V.
5) The digital potentiometer module comes with a test program, the program code is C language code, and is written in modules. The code includes: main function, display sub-function, key sub-function and header files of each module. You can use KEIL4 to open the source code for testing and learning.
Test part
1) If you only need to test the module, you don’t need to study the source code, and download the .HEX file in the test program to the target board.
