Pull up resistors stm32 reset circuit of 10 k hot, what is the

CodePudding user response:

System work?
1. Check whether capacitance on both ends of the short circuit, most likely,
2. Check whether the NRST is wrong pin

CodePudding user response:

STM32 reset circuit is not recommended to add resistance, external a 0.1 UF capacitance

CodePudding user response:

Connection capacitor grounding can again

CodePudding user response:

refer to the second floor weixin_43061026 response:

Connection capacitor grounding can again

reference 1st floor zhouml_msn response:

system to work normally?
1. Check whether capacitance on both ends of the short circuit, most likely,
2. Check whether the NRST is wrong pin

Should be normal, I perform other operations are running normally is hot

CodePudding user response:

If R1 measurement under 10 k

CodePudding user response:

Upstairs right, 10 k resistor if directly connect 3.3 V power supply (3.3/10000=0.33 mA) should not be hot, unless the value is wrong, to a few European level to get hot
