STM32F4 Discovery to XPT2046 (ADS7843)

ivan47 · April 12, 2015

This is link to my Keil 5 project. All user modified files (defines.h, gfxconf.h, gmouse_lld_ADS7843_board.h etc.) are located in

\01-STM32F4xx_Keil_CMSIS_uGFX\User.

I'm using STM32F4 Discovery board (it uses 8 MHz external crystal), ILI9341 display controller with SPI interface, XPT2046 touch screen controller (also uses SPI).

I'm using Tilens libraries to send data over SPI and for initialize (makes life easier).

Pin descriptions are in defines.h :

#define ILI9341_CS_CLK                RCC_AHB1Periph_GPIOC
#define ILI9341_CS_PORT                GPIOC
#define ILI9341_CS_PIN                GPIO_Pin_2
/* WRX or DC pin */
#define ILI9341_WRX_CLK                RCC_AHB1Periph_GPIOD
#define ILI9341_WRX_PORT            GPIOD
#define ILI9341_WRX_PIN                GPIO_Pin_7
/* RST pin */
#define ILI9341_RST_CLK                RCC_AHB1Periph_GPIOD
#define ILI9341_RST_PORT            GPIOD
#define ILI9341_RST_PIN                GPIO_Pin_6

#define TM_SPI3_PRESCALER	SPI_BaudRatePrescaler_2

This is link to my Keil 5 project.

Looks like the actual link is missing.

I realized I didn't paste the link...

I will paste it ass soon as I establish connection with my Cloud server

ivan47 · April 13, 2015

Sorry guys. I had some problems. My Internet provider is doing lousy job providing Internet, so I couldn't upload a file

online. Anyway here's the link:

http://www.mediafire.com/download/er4f5 ... ILI9341.7z

It is whole Keil project but like I said, user modified files are located in \01-STM32F4xx_Keil_CMSIS_uGFX\User.

I will look at it in the next few days. Sorry i can't get to it earlier, it's just very busy at my real work after the easter break.

ivan47 · April 13, 2015

Ok, thanks.

Joel Bodenmann · April 13, 2015

Same here, sorry. I won't have any time until Tuesday evening next week.

No worry, I'll work on my "primitive menu libraries" until then.

ivan47 · April 22, 2015

Did anyone figured out what is wrong ?

inmarket · April 22, 2015

I have not had time yet unfortunately. Work has been extremely busy.

There has however been something else that has come up that may be an issue...

Try using GOS_RAW32_HEAP_SIZE to invoke the use of the raw32 memory allocator. Some third party (including ones like the arduino versions) cannot handle being called with a non - native stack base and thereby cause the application to crash in unexpected places.

If that doesn't work please let me know and I will make a bigger effort to allocate that time I promised.

ivan47 · April 23, 2015

Okay, I'll do that when I find some time... Exams just started so...

ivan47 · May 10, 2015

Okay, I finaly got some time so I did what inmarket said, I defined GOS_RAW_HEAP_SIZE to 512, but nothing changed.

Sorry for it to take so long but I finally got some time to work on some strange crash issues.

I found a problem with the raw32 scheduler that affects some of the more recent gcc versions. If you can please load the latest master and see if this fixes your crashing issues.

This forum entry will provide more information on what was found.
