[i=s]This post was last edited by youki12345 on 2014-11-27 11:19[/i] The STM32-Nucleo board recommends an online compiler, but we are still used to using MDK. So how do we use MDK to develop STM32-Nuc...
Last night, I added reset, start, and pause. I also added a buzzer. The sound is too small, and you can only hear a little sound when it is close to the frequency of 625hz. The IO that controls the bu...
LED headlights require 3A 100V or higher power automotive-grade Schottky diodes. At the same time, due to the high temperature working environment, the heat dissipation effect of conventional packaged...
A few days ago, I played with the AD7606 module. AD7606 has two measurable ranges, one is ±5V and the other is ±10V. Because the voltage I want to measure exceeds 10V, it exceeds both ranges, so I won...
Dear experts: I can download programs to the target board through JTAG or SWD using ST-LINK and J-LINK, but when I change to another board, only VDD GND JTMS JCLK is brought out. No matter I use JLINK...
I am confused about the capture function of the LPC2148 timer. Can anyone explain it to me? After I set a pin to the capture function, if I connect this pin to an external clock, can I capture the ris...
