How to use 1 channel encoder on STM32F103?

[HPham.1590]

Hello, I'm using STM32F103 on CUBE MX, when I used an encoder which has only 1 channel, nothing was added to encoder register. I get data from this function: __HAL_TIM_GET_COUNTER(&htim3).

So does it has any different when we config encoder mode with 1 channel and 2 channels?

Many thanks
