Hello,I have matlab 2015b and I can not use simulink blocks of MAT-TARGET whereas the datasheet v2.2 claims that it can.Simulink tells me that the blocks have been done with a newer version (R2016b) and can not be used.Is there older blocks for 2015b?Regards

..

I am really confused that is it necessary or not. Because if I am going to the series STM32F030 these controller doesn't have in built EEPROM memory.

Hi,I'm trying to run the "Test_PIL_IIR_Filter" example and during the build I get a configuration error for the toolchain used by the parent file and the child file.In the configuration parameters window, the selection menu is grayed (not available). How can I change the toolchain for the child ?Regards,Bruno

Hi,In my next try to run the "Test_PIL_IIR_Filter" example, I'm faced with an other error.Does someone can help me on undersdanding and fixing this error?Regards,Bruno

I try the STM32demo /PIL/Test_PIL_IIR_Filter with the matlab 2018， ###Startup file:    ###Startup path:    ### Start compile .c source IIR_Filter_int32.c   ### Successfully compiled source IIR_Filter_int32.c   ### Start compile .c source main.c   ### Successfully compiled source main.c   "### BUILD_MODE model_reference"   "### Generated IIR_Filter_int32_rtwlib.lib model_reference"   "### Created IIR_Filter_int32_rtwlib.lib successfully (or it was already up to date)"   ### Real-Time Workshop build procedure for method: 'after_make  ### modelName: 'IIR_Filter_int32  ### gcs: 'IIR_Filter_int32  ### bdroot: 'IIR_Filter_int32  ### Real-Time Workshop build procedure for method: 'exit  ### modelName: 'IIR_Filter_int32  ### gcs: 'IIR_Filter_int32  ### bdroot: 'IIR_Filter_int32

Hi,Using Windows 7,MATLAB R2018b,STM32-MAT/TARGET 4.4.2uVision V5.22.0.0I'M trying the STM32-MAT\STM32\STM32demos\PIL\ADC\TestAdc.slx Simulink Model.

I use the STM32demo /PIL/"Filter" with the matlab 2019a, Then , I get the next information And when I used the matlab 2018b, there are some others errors"invalid index"", if the STM32-MAT target is older ? so which matlab version is best matching? @Amel NASRI @PascalR

Hello!I have installed the ​STM32-MAT/TARGET toolbox.My operating environment：matlab 2018bSTM32CubeMX 5.1.0STM32-MAT/TARGET 5.1.0​There are two question about CAN communication example!​Question 1:There is a error about CAN_IT module as follows when I simulate the CAN communication example in STM32demos.​I have tryed to solve this error.However,It seems that we need to modify S-function.But the S-function is saved as .p file,we can't view and modify.​Question 2:I want to delete CAN_IT module and simulate in polling mode.However,it still can't send or recieve CAN messege.The CAN state which gets from CAN_Get_State module is always “reset�?.The attached are the Simulink model and the .ioc configuration file for STM32CubeMX of question 1 and question 2.Please any help! Thank you!

Hello, I' m working in team on a project using stm32 f100 series board. I should use an eeprom to storage and read some data, the eeprom is the following: CAT24C512WI-GT3 and I also have the init code for this I2C eeprom:void io_ee_scl(char s) { if(s) GPIOB->BSRR=GPIO_PIN_6; else GPIOB->BRR=GPIO_PIN_6; }   void io_ee_sda(char s) { if(s) GPIOB->BSRR=GPIO_PIN_7; else GPIOB->BRR=GPIO_PIN_7;   }   void io_ee_wp(char s) { if(s) GPIOB->BSRR=GPIO_PIN_5; else GPIOB->BRR=GPIO_PIN_5; } char read_eeprom() //read eeprom function { return ( (GPIOB->IDR&GPIO_PIN_7) ? 1 : 0 ); }so I know the pins conected to my eeprom. Considering I'm new in stm32 I need your help to understand how I can read and write datas on my eeprom.... Thank you

Hi,I just uploaded the MPU6050 library to communicate with my STM32F103.Example program is MPU6050DMP6.All works fine when I use I2C1 (default I2C bus).But I want to use the I2C2 bus (controller has 2). I found information stating: #include "Wire.h"extern TwoWire Wire1;And in my setup part use:    Wire.begin();    Wire1.begin(); /Wire1 should use second port...For the rest there are no more Wire instructions in the MPU6050_DMP6 program.I can compile it, but when downloading, it just crashes....Any idea's what goes wrong or where I can find more data?Thank you

Hi!This is my first post on this forum.I just got an STM32F103C8T6 board from Ebay, ( https://www.ebay.com/itm/STM32F103C8T6-Minimum-System-Developmen-Board-Module-Core-Learning-For-Arduino/323747797666?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 ) and I have a question regarding programming it.I use Arduino IDE 1.8.9 for programming and the correct board manager.For upload I use an USB FTDI card that I run in 3.3V mode. I have connected the FTDI as follows: VCC to 3.3V, GND to GND, RX to A9 and TX to A10.I load the Blink example and upload it to the board using arduino IDE. The settings I have used in Arduino is Board: Generic STM32F103C seriesVariant: STM32F103CB (20k RAM 64k FlashUpload method: SerialCPU speed: 72 MHzI have switched BOOT0 jumper to "1" position.The program uploads and this is what appears in the output window:http://stm32flash.googlecode.com/Using Parser : Raw BINARYInterface serial_w32: 115200 8E1Version    &nbs

Hello,My O.S. is Linux Lite (ubuntu).I am getting "No such port: '/dev/ttyACM0' msg when I try to open the internal serial monitor in the IDE. I also tried /ttyACM0, etc.. When I use the Aruduino ide I can access the port successfully.ThanksTop

I am using the System Workbench as IDE with a STM32F746G-DISCO Board. I am trying to build an application based on the Audio_Play_and_Record Example. Now I am having problems with debugging the project, because every "Step into" action I try to make, I land in the "HAL_HCD_IRQ_Handler" and it gets a never ending cycle. My Question is if there's a way just to exclude a certain part of code from the debugging session, like in my example the "HAL_HCD_IRQ_Handler" function? Or any other solution I can't think of?Thank you for every possible answer, maybe it helps.If I forgot to mention an important info to solve the problem please tell me.GreetingsMartin

Hello,We are using application with stm32, and all works well.But we now want to divide it into: bsp HAL library and an application.The issue is that we are not sure where the interrupt files should be inserted and the start assembly files.Does anyone knows if it is possible to divide the big application like this , and where to put the interrupts and assemble files ?Thanks,ran

i have called a function big , and then found some memory overwrite

Hi everyone.I have been properly working on my project up to now but however i'm gettting this error when i start debugging. I don't remember if i accidently change any settings in my project. What are the possible causes of this "No source available for "__aeabi_dadd() at 0x80001e4" " error.Thanks a lot. Note: I configured as hardware implementation and FPv4-SP-D16.

I loaded a blank Arduino program, and now it's not recognized by mass storage (USB). Is there a way to get the board back? Do I need to buy a special cable? run a certain program?

Hi,I want to use the STM32F302R8 evaluation kit to create a sensor board. I would like to have around 10 input signals and use the Simulink Tool to create the code and, most importantly, to visualize in the Simulink scopes in real time all the input signals.I have given it a go, here's a picture of my Simulink "code":the input is at pin D13 - there is a square signal with period smaller than 0.1 second, which makes the LED on board blinking. Then, I have a wire on board that connects pin D13 to pin D8. I see the output of pin D8 through the scope in Simulink in real time. Everything works fine as long as the sampling time of the square signal into pin D13 is equal or higher than 0.1 second.If the sampling time is lower than 0.1 second, then it looks like there is some data missing and I got results like this one:It is fine if the sampling time can be big (above 0.1 second) but for my application I need a smaller sampling time.Was wondering if any of you had the same problem/issue and i

There seems to be a problem when trying to program an external flash chip via TrueStudio.I have created an external loader to program a QSPI chip that is connected to an STM32F469II.My loader is working via the "STM32 ST-LINK Utility", "STM32CubeProgrammer" and STM32_Programmer_CLI.When I try to use the loader via TrueStudio I run into the problem that the external memory is not programmed.I have selected the external loader via the property screen of the debug configuration.When I try to program the device when the external loader is set I get the following error.the log message that I get when programming.STMicroelectronics ST-LINK GDB server.

HI everyone, i'm trying to do an a SPI communication between the board STM32F746 and the MAX7219 to controller a matrix. i'm working in keil uvision 5 and programming without libraries, DMA, CMSIS or other. i programm through registers putting '1'. i want a full-duplex communication, as slave and onliy are one slave. i add the code that i do. it's on spanish that is my languaje. i hope that all can understand me and solve this. thanks // Code /* Pines: PB3: SCL PB4: MISO  PB5: MOSI */// ************************ LIBRERIAS ************************ #include <stdio.h> #include "STM32F7xx.h"// ***********************************************************// ************************ VARIABLES GLOBALES ***************// ***********************************************************// ************************ FUNCIONES ************************ void enviar_datos(char comando, char dato){ char recibido=0; // Espera mientras la busy flag esta activa while(!(SPI3->SR & SPI_S

Hi, there, I am not sure this is the right place to ask if it's concerning IDE.Just got my new STM32H747 Discovery kit, running CubeMX examples,All running well, except for debugging:(I am using MDK Keil (V5.27 / V5.28) and on-board STLink V3)I found that while debugging, if the data memory is outside DTCM (0x20000000~0x2001FFFF), Keil's watch window and memory window just don't update as program executes.That is, I can still see the data variable address in the watch window but the data just don't update as the code execues. So far I've seen that if data are in AXI SRAM or SRAM4, the data just don't update. I am not sure if this is ST-Link setting problems or Keil IDE problem.I would like to know if anyone faces the same issues, if so , is there any solution?!Thanks for reading this post, :) Zt.
