Hi,I've set up timer in PWM mode with circular DMA in CubeIDE.I would like to change buffer with halfcplt and cplt callbacks but i have no idea how to do that. I can't find any example on internet neither in documentation.Should i somehow register th...

Hi! I know overall idea of DMA and i need to use it but i have no idea how to do it. I found one post with same question but i didn't found any helpful info for me. I'm not advanced in case of using registers. I used them to directly change CCR and A...

as i said above, i can't find it anywhere edit: ok, hal is confusing

I've seen callback for ADC and UART several times on google but i can't find such just for timer in pwm mode

It turned out that i don't need DMA at all. I thought I needed because weird things were happening when i was updating ARR directly with TIMx->ARR = y. It turned out that I was doing that when counter was waaay beyond my y value. I just added line to...

It does not work, just returns HAL_ERROR. Standard version is working correctly.Also your example is not correct, when you are calling the function you should put uint32_t pointer as pData, not uint8_t. When i changed that it was working back again.

You use HAL_TIM_PWM_Start_DMA function but if i understand it correctly, it can access only TIMx_CCRx registry but i need TIMx_ARR
