STM32F411 Disco incompatible with STM32F4DIS-LCD?

richoxski

Hi all,

 

I have had an STM32F411 Disco board for a while now along with the baseboard.

 

I have only just recently hooked up the STM32F4DIS-LCDSTM32F4DIS-LCD TFT display only to find out that the example code that can be downloaded is not compatible with my controller.

 

Unless I'm mistaken, the F411 controller seems to be incompatible with the TFT display.

 

From the reference manual, the F411 lacks an FSMC which is what is used in the example (The F407 controllers which are the basis of another discovery board do have an FSMC).

 

I want to begin using the LCD, so my solution is easy - Get the F407 controller.

 

But I was wondering if an alternate solution to the FSMC is possible and viable with the F411 controller? e.g. Bit banged GPIO interface

 

Has anyone attempted this with the disco boards or has anyone got a completely different solution

 

Cheers

 

Rich

    You'd need to wire power and SPI lines across to the module from the processor board. You'd also have to rearrange the mode selection resistors so that it started in the right mode (moving R5 resistor to R1 placement and R6 resistor to R2 placement would get you the SPI 3-wire mode).

     

    But, given that you'd then have to also rework a whole lot of code to drive it, it would probably be much simpler, as you've already said, for you to use the processor board that the module was intended for.

    Hi Jon,

     

    Yes - That may prove quite a challenge. It would be good if they provided a module that was flexible enough to allow mode changes and corresponding code.

     

    I will still have a crack at the bit banging - Its silly that there is now solution for the F411 boards. But I now have an F407 board so I can at least use the LCD.

     

    Cheers
