ex.2 in ch11 (TIM in DMA polling mode) doesn t work.
i build examples from STM32CUbeIDE
built process has no error but led is not blinking.
Someone can help?
Read Carefully
In STM32F2/F4/F7/L1/L4 families, only the DMA2 has full access to the Bus Matrix. This
means that only timers whose requests are bound to this DMA controller can be used to
perform transfers involving other peripheral (except for the internal and external volatile
memories). For this reasons, this example for Nucleo boards based on F2/F4/L1/L4 MCUs
use TIM1 as base generator.
In STM32F103R8, STM32F302RB and STM32F334R8, STM32L053R8 and STM32L073RZ
MCUs TIMx_UP request does not allow to trigger transfer between memory and
GPIO peripheral. So this example is not available for the corresponding Nucleo
boards.
