Is there a HAL example of a memory to memory, or memory to peripheral DMA operation triggered directly by a TIMER event (not via a timer ISR) on the STM32H7?

I've read a ton of app notes, the STM32H7 reference manual, posts here, and I can't figure out how to have the timer UP event trigger a DMA operation. I'm sure this is obvious to someone with more understanding and could be gleaned from other STM32 m...

STM32G030J6M6, SPI

Hello.Is it possible to use hardware SPI with  STM32G030J6M6 (SO-8)?SPI1 use PA1 (NRST pin) for CLK without remap possibility.SPI2 also use PA1 (NRST pin) for CLK, but has CLK remap to PC14. In that case no MOSI pin.I try to use SPI1. PA1 configured...
