Measuring oscilloscope output ripple and dynamic response of low voltage (<1V)/high current (30-150A) power supplies has always been a challenge, with each new setup bringing its own errors. Errors in...
I am using the YLS3C2440 development board recently and I am going to use a GPRS module. This module is a USB to serial port. I connected it to the development board through the USB port and connected...
I am curious. There is no code. Can it adapt to motors with different parameters? I plan to learn more at the TI live on September 26.TI launches the industry's first codeless, sensorless FOC 70W BLDC...
Currently, ST BlueNRG -LP has realized the pairing function as a slave, in which pairing can be initiated by both the host and the slave. How can I prohibit the host from initiating pairing?...
According to my weekly plan, I have to build a circuit to power the microcontroller. Then I designed a 5V circuit diagram last time. I found a few resistors that are closest to the voltage. I soldered...
