I took a look at it when it was first released, and I passed the exam. I feel it's pretty good. It's quite suitable for beginners, but I don't know if the author has time to improve the course. I hope...
I am a newcomer in the world of electronic information engineering. As a newcomer, I have an obsession with technology. I always think that one day I will be able to play with single-chip microcompute...
I use DMA to read the serial port data "￥1234", 5 characters at a time, the first character is ￥. If there is an error, I will start reading from the second '1' and reread it if I find it is wrong. Wi...
In today's society, heart disease has seriously affected people's life safety. Many patients with sudden heart attacks are threatened because they cannot get timely treatment. Traditional ECG monito...[Details]
In some applications, such as data loggers, it is desirable to have multiplexed analog outputs. When only a single output is active at a time, a voltage-output DAC">digital-to-analog converter (DAC) a...[Details]
Pulse oximeters, non-invasive instruments used to monitor a patient's blood oxygen saturation, are benefiting from moving away from expensive discrete component solutions toward more integrated design...[Details]
Currently, it is impossible to dynamically obtain patient information in medical monitoring. Once the patient's condition worsens, emergency treatment cannot be implemented in the first place, and the...[Details]
