Struggling to use Atollic TrueStudio v9.0.1

jpnbino — Sat, 29 Sep 2018 06:16:30 GMT

Hey there,

I've recently purchased a STM32F4DISC board and I'm having trouble to use the TrueStudio. I feel that is not enough documentation out there. Does anyone recommend it or can point to another tool?

I gave a try to Truestudio because its free ( fully- featured)

Oh, also, I haven't understood yet the folder structure so I can make a proper .gitignore file.

any help appreciated,

thanks

Edit: I already used MDK and IAR to run some codes and I didn't have problems with them, they were pretty straight forward. It happens that both tools are limited and as David pointed out in the comments the TrueStudio was purchased by ST and made it all for FREE. Also, TrueStudio runs with GCC compiler and integrates with git, therefore I considered to use it for my projects, but it seems lack in proper documentation about itself ( I even haven't been able to program my target without debugging and it seems to run slow to compiler or navigate). I guess there is some configuration out there to make my experience more fluid.

Note1: My PC is a core-i5 7th gen, 8GB RAM DDR4

Note2: About run slow, I had been working with Cypress PoC Creator and MPLABX succesfully.

I need to connect them together.

Do I need to solder something to the BB board test point 22 and then connect it to the camera connector XCLK

can I just use whatever timer output pin and set it to generate 24 MHz or whatever frequency I need directly?

What is M+? What voltage it requires to power it up?

Please advise.

Thanks.

How to use the other UART in sn8200(Discover Wi-Fi)?

Former Member — Tue, 23 Feb 2016 05:22:31 GMT

Hello,

I am a new in this conversation;

I have difficulty handling Discover Wi-Fi.

Currently, I am using keil vision and stm32f407 as a host mcu device

Also, I am trying to modify the example code but it is not working well. I need help and advice.

In the example, PB6 and PB7 are used to communicate with host mcu. Unfortunately, I have already assigned these pins to the another function. So I changed and tried several times such as UART1 to UART2, UART1 to UART3 and UART1 to UART1(PA9,PA10)

Surprisingly, It is only operated in PB6,PB7....

Does anybody know what happen in here and how to change it?

I tried the EWW website and others... it did not work..

I am really looking forward to meeting your answer.

Thanks

STM32F4 Discovery - problem interfacing SD card

Former Member — Fri, 04 Sep 2015 13:27:04 GMT

Greetings all,

I am trying to make STM32F4 (on STM32F4 Discovery board) write a text file on an SD card, but with no success at all. I have tried this example by clive1 (flashing with hex/bin file directly). And also I have tried both, SPI and SDIO examples from this site. In the project from second example I placed "debugging" LED after the line: if (f_mount(&FatFs, "0:", 1) == FR_OK) And it seems the if condition isn't met, because LEDs don't turn on. Program ends in while(1) loop.

I believe my wiring is ok and also I am using new Micro SD card (tried also SD with SPI), but no success. Does anyone have any suggestions, please, how I could resolve the problem?

Thank you and kind regards,

UVC for STM32F429I Discovery Board

Former Member — Wed, 08 Jul 2015 12:29:47 GMT

Hi,
I am developing a webcam like application with STM32F429I. I am using the discovery board for my development.
I wish to configure the USB 2.0 as a UVC device. I have instantiated the UVC code available at github.
I am successfully able to connect my kit to the PC, however the USB driver on the PC shows my device as a unknown device.
Kindly suggest if any driver is available to interface the board with the PC as UVC device.

Thanks & regards

STM32F4 Discovery LCD Expansion board with touch as interrupt

Former Member — Thu, 14 May 2015 17:49:55 GMT

I would locate the pin in the element14 expansion board with lcd. I think that I have to locate the pin in the STMPE811QTR used to raised interrupts and connect it to one of the STM32F4Discovery. My question are: How can I do that? What is the interrupt pin in STMPE811QTR and how can I reference it in my code? thanks

Discover Wi-Fi Module SPI Communication

Former Member — Sat, 31 Jan 2015 23:26:43 GMT

I've been messing around for days and have been unable to get the SPI communication with the Wi-Fi module to work, it would never respond at all. I couldn't get the demo UART code to respond either, but I need SPI for the increased bandwidth anyways. Am I doing something wrong, like missing a setup step or something? I'm not even sure if I connected the correct pins on the board, as there are 2 sets of SPI pins (SPI and SPI3), and I'm not 100% sure of which pin is the "ALRT" pin. I couldn't even get that interrupt to fire, despite numerous attempts to send data to the module. Does anyone have some working SPI code and wiring? I'm kind of at a loss here. I've put the code is this gist and this gist (too many lines to paste here), it looks rather shoddy as I was trying various things to get the module to do anything at all. I tried both DMAs and straight up interrupts, though I'd prefer to use DMAs to save CPU cycles.

When I try to build the wifi demo project I get the following error: "rtl.h: No such file or directory"

When I try to build the wifi demo project I get the following error: "rtl.h: No such file or directory"....Can somebody tell me what library do I need to get this error resolved?..I do not know if its just a matter of adding a include path or installing missing libraries.

STM32F4 Discovery board & ST-Link Utility - Core Lockup

Former Member — Fri, 26 Dec 2014 18:54:32 GMT

Greetings all,

After about a year I have returned to playing with STM32F4 Discovery board. Last time I have used the board and ST-Link Utility everything worked as it should.

This time however, it doesn't. I connect the board with ST-Link ( USB driver ), erase the flash, and upload a .bin program ( the demo program that MCU came flashed with at purchase ). Hex program and ST-Link worked well last time I used it.

Now when I go to Target -> MCU Core and select "System Reset", I get "Core State: Lockup". Therefore I can't Run the application ( I get "Unable to run application" ).

What could be the problem in my case ? What could change since the last time I used the board, when it all worked well ?

Thank you and kind regards,
A

Cannot build WiFi_Demo_V2.2_20130620 in MDK-ARM-Lite 5.12 - rtl.h is missing

hetcnc — Wed, 19 Nov 2014 15:00:15 GMT

I am trying to build demo code for the Discover-Wi-Fi board - "WiFi_Demo_V2.2_20130620". The problem is build fails as it cannot find rtl.h header file, which is needed by sn8200_core.h and sn8200_api.h.

I have searched for it in Keil MDK-ARM-Lite 5.12, but there is no such a file. I have installed Keil software pack for STM32F4, but it didn't help.

How to make it build?

Problem with http request

Former Member — Wed, 29 Oct 2014 12:12:27 GMT

Hi, we work with st discover wifi and we are using the api that the module have in the web. But we have a problem when we send a req from http. Sn8200 return this

.HTTP RSP code: 8448, seq#: 0, Content Length: 0, Type: , More data: no. What is the problem?

Pd: We are using CoOS as real operative system.

This is an example to the code:

strcpy(domain,"www.murata-ws.com");

sendHttpReqTest(domain, 0);

int sendHttpReqTest(char *domain, char isHttps)

{

char tmp[100];

char method = 0; //GET

char contentType[] = "text/html";

char otherHeader[] = "";

char content[] = "";

unsigned char timeout = 10;

printf("Enter URI after the server name: ([CR] to accept %s)\n\r", uri);

strcpy(tmp,"/");

printf("\n\r");

if (strlen(tmp))

strcpy(uri, tmp);

return fillNSendHttpReq(seqNo++, domain, uri, method, contentType, otherHeader, strlen(content), content, timeout, 0, isHttps);

}

LCD35RT Example Program with stm32f407 with base board with LCD connected

Former Member — Tue, 28 Oct 2014 22:25:35 GMT

Hello

(I am just beginning so don't know a lot!)

I have just got into programming this chip and require some help I have tried for hours trying to get examples to work and fail.

I have downloaded the example LCD_35T which I can get working with the text and the three bars. but you cannot edit this program as it is a read only and I cant seem to change it.

I am hoping someone could send me a example of a program that would work so I can add to it. I am just doing the blinky projects turning leds on and configuring inputs and outputs and analoge inputs.

I just want to be able to printf to the LCD to help me fault find and maybe show the status of my inputs.

If anyone could help I would be grateful thanks!!

Discover WiFi - DNS Resolution

andyw999 — Fri, 03 Oct 2014 13:18:16 GMT

In sn8200_core.h there is SNIC_RESOLVE_NAME_REQ which is referred to in page 72 of the SN8200 SNIC Serial Interface Specification.pdf

(Optional) SNIC_RESOLVE_NAME_REQ to resolve a host name to IP address

If you try to do a query with it then handleRxSNIC get returned 0x8A which is not a member of SNIC_subcmd_id_e in sn8200_core.h, in fact it has been deliberately left out :-

SNIC_SEND_RSP = 0x82,

SNIC_CLOSE_SOCKET_RSP,

SNIC_GET_DHCP_INFO_RSP = 0x89,

SNIC_IP_CONFIG_RSP = 0x8B,

Does anybody know how to make this work and if the SN8200 UART firmware even supports it?

I have asked Murata but do not know if I will get a response...

Edit - just had a response from Murata and the version 2.3 of the SNIC serial interface specification.pdf is a lot more up to date.

Thanks

Andy.

Wifi Module API

Former Member — Wed, 27 Aug 2014 19:39:38 GMT

Hi,

I am using the STM discovery board and need a WIFI interface. I'm evaluating the module shown here. I want to understand how I send/receive data to this module. It uses a serial interface so how are TCP/IP packets delineated? Is there a document describing the software API.

I am using freeRTOS on this project so it would be great if it just "worked"....

Discover WiFi

andyw999 — Mon, 25 Aug 2014 09:42:13 GMT

Is it possible to get the source code for the SN8200 as I have a simple application that does not need the resources of an external CPU.

Thanks

Andy.

are there software examples for ethernet based on the HAL drivers?
