My project needs a lot of pictures, so I need to use external flash. The Norflash I use is w25q256 different from the development board n25q256. So I have to write my own stldr file. I use the mpu is stm32f469, but I can not find the demo project ...

My current project uses "en.stm32f4_dsp_stdperiph_lib", version 1.60, which implements the finished product function using standard library. Since stemwin GUI was added to use Mipi lcd, I found only a simple DSI example in the standard library.Does S...

Hi：Let me ask you a question. When use 32 bits of SDRAM in STM469 official routines, DMA is configured as follows: /* Configure common DMA parameters */ dma_handle.Init.Channel = SDRAM_DMAx_CHANNEL; dma_handle.Init.Direction ...

Your answer gave me an idea. The current version of my product is built on SPL using the IAR compiler. I need to add a DSI driver. Can I mix HAL and spl? Can I compile the HAL and SPL libraries in one project? If the compilation is successful, I have...

Thank you for your reply�?It's sad to hear that reply. Because this means that previous projects developed using SPL will be troubled by updating module functions and developers who are already used to using SPL in the future.

Because the data width of my product SDRAM is 16 bits. So I wonder if I want to change the data width of SDRAM dam to 16 bits.
