I use GPIO to simulate I2C to operate EEPROM (24C512), but I can only read but not write. The EEPROM hardware is not write-protected. When writing, each ACK is normal (low level). However, in the main
1. Purpose
The microphone array is arranged in an array to focus on picking up the sound signal in the space, so that the picked up sound is enhanced and the effect of long-distance sound pickup is ac
Help
I want to make a boost and buck circuit, but there is no buck. How to fix it?
As a result, the output pin voltage is the same as the input pin voltage, both are 3V
