STM8L051 TIM2 & TIM3

Can TIM2 or TIM3 be attached to a quadrature encoder and up/down count? The data sheet says yes, but the reference manual is vague. Has anyone attached an encoder to these Timers yet?

Did you ever get a reply to this question as I too was wondering the same thing!? However, from what I've seen built in support for quadrature encoders via timers appears to only exist in the 32 bit devices.

Thanks,

Ian

I think the manual is quite clear, only advanced timer TIM1 has encoder modes.

The relevant settings are marked as reserved in general purpose timers(SMCR_SMS).

I suppose it's a bug in datasheet.

Hello,

Does anyone know if there is any example code showing how to use a detent rotary encoder with TIM1 in encoder mode?

Thanks,

Ian
