I haven't had a sample for a long time. I heard that TI is now strict about sample application. People who used 163, QQ and other email addresses before can no longer apply. I decisively applied for a...
When creating a new project file for simulation, an error occurs: "target voltage seems to be below operating range for this device family. Make sure the target is powered on and try again." I have tr...
The EEPROM datasheet has the following description: If you use GPIO to simulate I2C to operate the EEPROM, 1) How to distinguish whether it is Standard (100kHz) or Fast (400kHz)? 2) How to use the fol...
The motor (12V/20A) is driven by a half-bridge, from (power supply +) -> (high side) -> (motor +) -> (motor negative) -> (power supply negative); all are covered with very wide copper foil. Question: ...
