How to setup a Timer to output a squarewave?

The Cube is not clear in this. I want to output squarewave 1kHz-0.1Hz from a pin. There are no examples about this and explanations are not clear either.

I want to use STM32F1 CPU. #je-ne-l'aime-cube

PWM with 50/50 duty,Toggle?

50% off, 50% on, it is not very critical. What is toggle in this context? Keying or gating with an other signal? Let's keep it simple, I can fine tune details myself, I hope.

I found a DM00154093 pdf which talks about the Cube in a way. There is something about timer modes and the Cube tool itself has something similar. I understand a little more about the Cube. I'll try again with the project.

And with  extra parenthesis. Code from the Cube: else if((htim->State == HAL_TIM_STATE_READY))

I found an example which does what I want

STM32Cube_FW_F4_V1.11.0\Projects\STM32F4-Discovery\Examples\TIM\TIM_TimeBase There are no CubeMX projects in those packages. I wonder why. I'll ask ST to include CubeMX projects in their examples.

Hi mich.lei,

You find the examples for STM32F1 at

http://www.st.com/web/catalog/tools/FM147/CL1794/SC961/SS1743/LN1897/PF260820

at this path stm32cubef1\STM32Cube_FW_F1_V1.3.0\Projects\STM3210C_EVAL\Examples\TIM

The CubeMx does not aim to create a hole project but , infact, it helpsto generate an initialization code to be a start point for the project developement. -Hannibal-

I just noticed a new post.

We are talking about projects and CubeMx projects. In my opinion Cubemx is a good idea, I mean the visual setup the HW. But it must be used and supported. Giving just initializing code without CubeMx is not so useful, there already is one such interface, I think. Timers have quite many operating modes, so they are one place where CubeMX could help. Besides, Cubemx shows which pins are available and which are taken.
