The schematic diagram is attached. Now use 2 PWM to control the 2 channel op amps of LM358 to output 0~10V respectively. The problem occurs: PWM with the same duty cycle: Channel 1 outputs 10V Channel...
I originally planned to modify the example and add the function of serial port outputting temperature and humidity data, but I don't have the J-LINK download tool for the time being. At the same time,...
[size=4]Background description: This is a low-power single-phase photovoltaic grid-connected inverter. When it is powered on again after a large-scale power outage in the city grid, the resistor R1 in...
The AD of the MSP430F169 I selected has large fluctuations when sampling. AD is the internal reference. I still cannot achieve stability after averaging the data. Using an oscilloscope, there is a lar...
I'm new to Stellaris. The only USB routines I've seen are from BULK, and they're written using library files. I read the source code, modified it, and compiled usblib.a, but I don't know how to use it...
The intelligent driving community has its own rhythm. Some are busy pushing new versions and focusing on R&D, others are busy with publicity and promotion, and still others are immersed in mass pro...[Details]
Flip-chip and ball grid array (BGA) are two widely used packaging technologies in the electronics industry. Each has its own advantages and limitations, and in some cases, they can complement each ...[Details]
New energy vehicles are increasingly popular with consumers due to policies and energy conservation. Once you've purchased your vehicle, maintenance is essential. However, due to the different powe...[Details]
