DMA_ISR with active bits even if I didn't enable the interrupts
Hi,I'm working with DMA on an STM32F745. I have enabled a DMA interrupt for Transfer Complete on SPI RX, when the data is ready to be read. To do this, I set the TCIE bit in the DMA_SCR register. In the interrupt routine I read the data and I disable...
Resolved! What is better "Direct Resistor access or using Library"
Hi all,from last 8 yrs i am writing programs for microcontrollers (mostly project on microchip, st) 8 bit/ 32 bit.i always write programs by writing directly to the registers. i never used any library like SPL, HAL, LL doesn't matter how long the cod...

Operating SD Card at 1.8V directly
This post: https://community.intel.com/t5/Intel-Makers/Low-Voltage-Signaling-SD-Cards/td-p/490563 seems to imply that newer SD cards can operate directly at 1.8V with no translation to 3.3V. Can anyone confirm if STM32H743 supports this?If so, does t...
Timer registers to be updated simultaneously
Hi,I am using STM32G474 with TIM1, TIM8 and TIM20 and working with STM32CubeIDE.I want to updatethe ARR, CCR1, CCR2 and CCR3 regs at the same time. I taught that with the preload register it can be done but it doesn't work for me.So how can I do to s...
