Today I am using STM8L151K6 as output enable for ADP3110A, so I configured the IO port as follows: PC1
GPIO_Init(ADP3110A_EN_PORT, (GPIO_Pin_TypeDef)ADP3110A_EN_PINS, GPIO_Mode_Out_PP_High_Fast);
GPIO_SetBits(ADP3110A_EN_PORT,ADP3110A_EN_PINS); //Turn on ADP3110A_EN
However, the oscilloscope measurement revealed that it was only about 1.4V. Checking the data sheet
Found that there is only T7 in the output port. View comments
In the open-drain output column, 'T' defines a true open-drain I/O (P-buffer, weak pull-up and protection diode to VDD are
not implemented).
If this pin is set as an OD gate, an external resistor must be connected to enable a high level.
