The chip I bring to you is still produced by TI - ads1115.It is best to prepare the datasheet of ads1115 before reading this article.
1. Introduction to the chipADS1115 is an I2C compatible ADS111x, u
1. Current sampling (capacitors must be added to the input and output amplifiers)
To collect the current at a point, use a small precision resistor to collect the voltage, and then divide it by the re
The main reason is that the power supply line, power supply circuit, single-chip microcomputer, etc. have abnormal operation. Inspection and steps 1. First check whether the voltage of the power suppl
The kernel driver can not only compile the driver into the kernel, but also dynamically compile the kernel driver. This document describes how tocompile the kernel driver in a module way.To compile th
