Today I used the internal ADC of the msp430f149 to sample (P6.1) and measured the peak-to-peak value of p6.1 with an oscilloscope. The result was 12.6V. How can I explain this? Is the sampled voltage ...
How to rewrite the RTC counter to modify the time during program running in STM32? I use the Time_Adjust function of the program to write, but it cannot jump out of the RTC_WaitForLastTask judgment....
In the document, the CAN bus is based on information rather than addresses. I would like to ask a question. For example, there are four CAN bus nodes A, B, C, and D, and the data sent by each party ne...
The welding requirements of blue and green LEDs are the same as those of white LEDs. Based on the general level of white LED welding, there are such basic requirements. The following points should be ...
