I want to set up some generic SDRAM as a component (board) to support the
ILI9341 LCD screens. I tried a few boards now (L476RG, F407VE, etc.), but
all seem to come short in (SD)RAM fort he framebuffer.
What do you advise? And is there already a solution in Nuttx for it?
There are dozens of them. For the STM32 family that you seem to prefer,
there are only a few boards:
* stm32f429i-disco- 64-Mbit SDRAM
* stm3240g-eval - 16 Mbit SRAM
* stm3220g-eval - 16 Mbit SRAM
* stm3210e-eval - 8-Mbit SRAM
* axloti - 8 MiB of SDRAM (Alliance Memory AS4C4M16SA)
I prefer the NXP LPC54 to any of those, however.
Actually, my recommendation (as if I were doing the job on an STM32)
would not be to use any ILI9341 LCD but something based on the SSD1963
which as a 1,215Kb framebuffer built into the LCD controller. I love
that part and it has been on my list for a long time to buy an LCD with
an SSD1963. The are cheap. There are some around $45 on eBay.
