Re: How to internally pullup TX line when using HardwareSerial + HalfDuplex?

Hello,

I'm excited to let you know that I've fixed the issue I was having. It seems that you can't use an internal method to pull-up when using Half-Duplex communication. Someone in a discussion explained this well, and you can read about it here: Link to discussion .

Once I understood this, the ...

Hello fpiSTM,

Thank you for your response.

I'm a bit puzzled as to why I'm observing different behaviors. When I configure UART in full-duplex mode, I see the following waveform in the scope:

How to internally pullup TX line when using HardwareSerial + HalfDuplex?

Dear all,

I am utilizing a board based on the Blue Pill board for my project, aiming to establish half-duplex communication with UART-controlled servo motors. To achieve this, I am leveraging the HardwareSerial API.

However, I've encountered an issue: while sending commands to the servos using ...
