I configure the ADC1 of the STM32H735 like bellow:The ADC Clock = 20MHzADC_HandleTypeDef hadc1; DMA_HandleTypeDef hdma_adc1; /* ADC1 init function */ void MX_ADC1_Init(void) { /* USER CODE BEGIN ADC1_Init 0 */ /* USER CODE END ADC1_Init 0 *...

I have developped a graphical demo with the STM32H735 discovery kit, and the minimum frequency of the OCTOSPI to have a clean display is 66 MHz (framebuffer = 480x272x32). Now I want to use in my application an External RAM with QUADSPI (framebuffer...

Hi allI don't know what I'm going to say, but maybe you don't believe me.I put back the same configuration that I wrote in my question, and the ADC works correctly now despite there being no change.Apparently, I will spend some time reproducing the p...

Hi @Community member The only discovery kit I have found with an external serial RAM that can store a framebuffer is the STM32H735g-DK but it has HyperRAM with the octospi Hyperbus.In my project I have to use an external serial RAM with a no-BGA pac...

Hi @Aime Thanks for your reply.I didn't properly explain what I was asking for. I put my question differently.I am talking about the bandwidth of the external RAM.How do I calculate the bandwidth of a QUADSPI external SDRAM?Best Regards,Saif.
