Hello~ Everyone~ The new week's review information is here~~ Tomorrow is National Day~ I wish you all a happy holiday! Let's get back to the topic, let's take a look at the latest review information~A...
Use P1.2, P1.3, P1.4, and P1.5 as sampling channels, taking the demo's msp430fr231x_adc10_10.c file as an example.
1. Configure the above 4 pins to ADC mode:
P1SEL0 |= BIT2 + BIT3 + BIT4 + BIT5;
P1SEL...
Although the use of the STM32 DSP library for FFT is somewhat inflexible (because it is a radix-4 FFT, the number of FFT points must be 4^n), its execution efficiency is indeed very high, as can be se...
This is a single-power supply voltage follower circuit I designed to measure ±5V. The input terminal of the circuit is connected to a 5V voltage reference source. The circuit voltage is a "12V isolate...
If you want to have confidence in your oscilloscope readings, you need to understand the strengths and weaknesses of the different acquisition modes: normal acquisition, average acquisition, high reso...
The voltage and capacity of a single battery are limited, so in many cases, they must be connected in series to form a battery pack. However, there is a problem of balance among the cells in the ba...[Details]
