I am a novice in learning MSP430. I feel that this thing is very complicated. After watching videos and reading books for many days, I have gained a little bit. But now I have encountered a more diffi...
Is the keyboard connected to a fixed position for the arm9 chip? If it is not a standard keyboard, is it also in a fixed position? Is there any information?...
I have two 3.3V-1W isolated power modules on hand, because I need to power a 3.3V LCD and a single-chip microcomputer, but the power of the LCD plus the power of the board is greater than 1W. So I wan...
Suddenly I realized that I hadn't considered the tickets earlier this year. I remembered the experience of queuing for 3 kilometers last year, so I decided to shamelessly ask which great person can ge...
I recently helped a friend push some recruitment information and learned that the company has an internal recommendation mechanism. The people recommended by the company are equivalent to a level of s...
LT3572 is a step-up chip, VIN is 2~5V, Vout is 30V. During use, I used a voltage regulator to supply 3.3V, with a current limit of 100mA. After power-on, the voltage regulator dropped to 2.2V, the cur...
