Developing for STM324xG-EVAL board

[xlh1460]

I found board support files for ST_STM3220G_EVAL but no demos.

I am actually developing for a STM3241G-EVAL board but the boards are very similar (the PCBs, themselves, are identical)

If anyone has any working ones that they can share, I would appreciate it.

If not, I guess I need to get to work


Thanks.

I have no demos for you - however, you should be able to get demos from different boards working quite quickly since this is the meaning behind the board files.

I couldn't find out what TFT and touchscreen controller is used on that board - if you get those working, we'd be thankful for sharing your drivers and your board files

Hi,

Like Tectu explained you can start from any STM32F4 demo and swap the reference to the board in the Makefile (better start from a simple demo), then you need to fix the small differences such as LED names and port numbers in main.c.

I will definitely share anything I do including the support files for the display.

Incidentally, it uses the ILI9325 display chip and the STMPE811 for the touchscreen so I am hopeful that getting those working should be little trouble.

I copied the ST_STM3220G_EVAL directory to ST_STM3241G_EVAL and made the following changes to the board.h file:

Code: Select all

$ diff ST_STM3220G_EVAL/board.h ST_STM3241G_EVAL/board.h
27,28c27,28
< #define BOARD_ST_STM3220G_EVAL
< #define BOARD_NAME              "ST STM3220G-EVAL"
---
> #define BOARD_ST_STM3241G_EVAL
> #define BOARD_NAME              "ST STM3241G-EVAL"

> #define STM32_VDD                   330
>
> /*
40c46
< #define STM32F2XX
---
> #define STM32F4XX


Note that I need to add the board voltage as it missing and caused the following compiler error:

Code: Select all

Now I am getting the following errors related to my clock settings:

The board file has the clocks defined (correctly, I believe) as:

#define STM32_LSECLK 32768
#define STM32_HSECLK 25000000

Your board mounts a different crystal from the original one, you need to setup the clock-related parameters in mcuconf.h in order to have the PLL working in the correct range, this may require some study of the reference manual.

Giovanni

[xlh1460]

I see, I think.

My board has a 25MHz crystal but the mcuconf.h file in my project is one that I "borrowed" from the STM32F4-DISCOVERY demo.

That board has an 8MHz crystal which is why the settings need to be adjusted.

Is that about it?

[Giovanni]

Correct. you have to operate on:
1) input divider STM32_PLLM_VALUE
2) multiplier STM32_PLLN_VALUE
3) output divider STM32_PLLP_VALUE

Look at figure 13 on the Reference Manual in order to understand all the parameters in mcuconf.h. I think you just need to put "M" at 25 and drive the PLL at 1MHz like the other demos do.

Giovanni

[xlh1460]

You are absolutely right, I just changed the STM32_PLLM_VALUE value to 25 and it compiles fine.

I actually cheated and looked at the mcuconf.h file for an Olimex board with a 25MHz crystal.

I'll have a look at the reference manual too, though since this is pretty important stuff.

I am going to take a look now at porting some of the demos that come with the STM32F4 StdPeriph Library.

Thanks again for your support.

[xlh1460]

I have a very simple demo running on my board now which I have attached.

This exercises the 4 LEDs and the 3 pushbuttons available on the board.

[Giovanni]

Good job

Moving the thread to the contributions forum.
