I have DS18B20 sensor which works on the one wire protocol & it was interfaced to STM32F030C8T6 controller.
But it was failed to communicate(respond) with the device over UART2.Below is the uart to device connection Fig.
I am using 3.3V for to power the device and 2.2K pull-up on the bus(as mentioned in the datasheet).
How to Generate reset signal (480us low on the bus) on the uart pins for one wired device.
please help me on this issue
