Hi there,I'm currently trying to get SPI Communication with the LTC1403 up and running, however I'm struggling with the timing of the Conv Signal.It seems like I need the rising edge of SCK at the same time as the Conv Signal is high. How can I achie...
My linked-list object's base address in memory is 0x200bffbc. How can I save this address in GPDMA_CxLBAR register (that holds "the linked-list base address of the memory region, for a given channel x, from which the LLIs describing the programmed ...
Hello everyone. Question about synchronous launch of three timers.Given:- CPU F0 or F4 or G4 (of course F103 is possible - I just don't like it, personal dislike);- three timers, each with its own operating frequency, Timers work via DMA, each with i...
Hi!I have a doubt as to when to choose FMC and when XSPI in regards to working with screen GUI with stm32h7s7. In few youtube tutorials, they are using FMC to load data to the screen but in the development board ".ioc" for the same the XPI1 and XPI2 ...
