Author: Zhu Mingwu (Mingmo)The fuel gauge has three security modes: SEALED (locked), UNSEALED (unlocked), and FULL ACCESS (full access). Different security passwords are required to switch between dif...
I am using the msp430 2234 chip, using the timer to simulate the pwm output of the p3.3, and the p4 port is used for the led output. When I don't add the pwm output, the led display is very stable. Wh...
Why is the operating current of this circuit twice as large when the voltage is 12V than when it is 28V? The voltage range is 4.5V to 40V wide input. Does it mean that the higher the voltage, the more...
In the TTP299 chip, in the 16-key input mode, only the serial output mode can be used, using the 2-wire serial communication mode. How to write this method? Please give me some advice. It's urgent. Th...
Today, when I was adjusting SPI communication, I encountered a situation where the value in the send register was not what I wanted and an unexpected receive interrupt occurred. = (BIT2+BIT3+BIT1); IE...
Has anyone designed an integrated ultrasonic transceiver circuit? I recently want to make an ultrasonic distance measurement circuit. Now I have built a circuit by myself after finding information onl...
