STM32F407 FSMC interface with TFT LCD

I've written some code to make a FSMC connection between my STM32F407VET6 and a TFT LCD 240x320 pixels. I was checking this several times, however I can't recognize what's wrong. I'm using 16-bit data bus with FSMC_NE1, FSMC_A16, FSMC_NWE, FSMC_NOE.…

STM32F4 FSMC 8-bit data width with 10+ bit addressing

I'm planning to interface an FPGA to a STM32F29/439 via the FSMC (Flexible Static Memory Controller). To save pins I would like to use the address/data multiplexing feature. Thus according to the datasheet for 16-bit mode I have multiplexed signals…

invalid read data from nand flash

I want to use a nand flash ic with part number of K9F1G08U0C and connect it to a stm32f429igt6 microcontroller. Although I can read the ID of this nand successfully but the written data and read back, are not the same.- I just read 0x31 - I can also…

Finite state machine boolean expression

I'm looking at this mealy machine: and this state table with the boolean expressions at the bottom. If you look at the \$S_1\$ boolean expression, it says \$S_1 = \overline S_1 S_0 B + S_1 A B\ \$. Shouldn't it be \$S_1 = \overline S_1 S_0 B + S_1…

STM32F105 FSMC Pin assignment

How do I assign certain pins to the appropriate FSMC pins? I've looked through the reference manual and the examples, but there's nothing about pin assignment except configuring them as alternate push-pull. If it helps, I'm configuring the FSMC for…

Endianess on STM32F4 FSMC output

I'm currently setting up a STM32F407 to evaluate a display module which utilizes a Renesas R61526A Displaycontroller. I was able to set up the project using CubeMX no problem, and the FSMC seems to be working. However I noticed that the output…

STM32F407 FSMC & ILI9341 – 8 bit bus width works, 16 bit doesn't

I'm trying to use TFT display with ILI9341 8080 16 bit interface with STM32F407 via FSMC. I'm using HAL. To explain a bit more, for ILI9341 command registers only lower 8 bits of the bus are used, full 16 bit bus width is only used for transfer of…

STM32 FSMC/FMC and DS90CR285

I don't want to use an FPGA. I need to quickly put together a prototype that will relay DCMI data (small resolution camera sensor) to DS90CR285. Here performance doesn't matter that much – later it will be deployed on an FPGA anyway. However before…
