Hi everyone, I am about to download TrueAtollic studio for my windows computer, but when requesting a download for the IDE, it is asking for a business email id and choose between non-commercial and business, I only have a personal email ID. But I am yet to start my business, I would like to use the code on trueatollic/STM32CubeIDE on my products, but worried any complications when I download with the non-commercial option when I haven't even started my business and my product goes on sale. Is the same also true for STMCubeIDE? Which option should I select? And how should I go about using STM's IDE's in my product for commercial use? What are the procedures that I need to follow to put the code into my products for commercial use?Thank you!

​I can read and write normally after using the EE_Init(EE_FORCED_ERASE) function to initialize. But when I use the J-Flash tool to read back all the contents of the flash and save it as a .bin file, then erase the flash and download the saved bin file to the flash, I found that the program cannot write data normally.If anyone understands this situation, please help explain what the problem is？

hey allcan I use try{}/catch{} in keil IDE?

I use STM32F103c6 timer1 for pwm input . after right config in cubemx, and in simulink enable timer1 ch1 interrupt. Then auto code gen, but code in Keil the ch1 interrupt not enable, its callback not registered, the timer also not started. Want to know how to use timer1 pwm input in simulink, look forward to reply! Already Confused for one week ...

First of all, English is not my first Language, I hope you can undestand me. I'll try to explain all the details of my problem.I'm trying to get started using STM32-MAT-TARGET, and I've tried a very simple project but it does not work. First I started the project from STM32CubeMX V 6.0.1. I selected the MCU, not the board (to keep it simple).The push but (PA0) was set as input and the LEDS (PD12 to PD15) as outputThe clock configuration was left as default:Then I made a very simple model in MATLAB Simulink (2020a) with the following Model Settings for STM32-MAT-TARGET.The simulink model is very simple. If the push button is pressed, the LEDs will be on and if the push button is released, the LEDs will be off. I used the .ioc file generated by STM32CubeMXthe model was saved as "C:\Temp\Test0\T0.slx". Then I built the model by using rtwbuid in the matlab command line.Then I loaded the generated project in STM32CubeIDE 1.4.0 and built it. I was built with 0 errors and 0 warnings.My proble

Hi community,Actually I am having issue in getting output on serial monitor of arduino ide for my stm32f407 board. I tried installing SWO LIBRARY and SEMIHOSTING , but still unable to get a response.My serial is blank. But led blinking program runs fine. My upload method is stm32 cube programmer SWD.I am attaching my setting pic.​Please do suggest me a method. I am helpless since 1 month, I am new to the platform and I tried coding in stm32cube ide, but for my project i thought i could use arduino ide.​​

Posted on January 30, 2018 at 09:47Hi,I use the REG_Access block to read the value stored in the data register of the SPI1. So I change the 'Peripheral' option from NVIC to SPI1.But it always goes back to NVIC, once the the simulink model is closed and reopened again. If I don't notice this change and don't manually set it again, it will lead to errors while compiling the code in the IDE.My software versions are as below:MATLAB: R2017aSTM32 MAT/TARGET Library: 4.4.2Best Regard,qxj#stm32-mat/target-matlab #simulink

I already used MAT/TARGET and it works pretty good. Now I have a problem with SPI I can't find enough information to build my block diagram correctly with SPI. In particular I don't understand which type of data require in Input and how can I use simulink to generate a data store that I can use to send data trough SPI. Can anyone help me? may be with some example thanks

I can confirme this bug, onlye Timer on APB1-Bus are working with the target. When I'm use Timer 2 MATLAB runs into a infinit-loop. there are a Bug in the TIMER_config.tlc at line 531. When i use the timer in encoder-mode, it generate always an ISR but it is not configurated. When I'm change the following line everthing works fine. Compare the pictures below. this is also correct:  ISEQUAL(CH1_int,“on“)&&ISEQUAL(CH2_int,“on“)&&ISEQUAL(TIM_IRQ,“on“) 3. if have also configurate the timer-channel 3/4 as output compare with enabled interrupts. Every time i generate the code it will generate the HAL_TIM_OC_DelayElapsedCallback and the ISRs I'm use via the functionscalls from the timer-block (isr channel outputs).But in the HAL_TIM_OC_DelayElapsedCallback the the generatet code will override my compare values like this: /* Set the Capture Compare Register value */       __HAL_TIM_SET_COMPARE(&htim8,TIM_CHANNEL_1,(uint32_t)((cap

I used 7bit device address as 0x51. considering A16 bit as 1 for above 64k memory locations.I am able to write though. and I confirmed it by writing to above 64k memory locations and reading it by using 7bit device address as 0x50 and doing sequential read starting at 0xFFFF and continued reading further.but if I use address as 0x51 and start reading at location 0x010000(mem address in 16bit will be 0x0000) then I am not getting the data.

 I am using stm32 F746ZG Nucleo LQFP 144. I am using stm32 MAT-TARGET to generate c code from my simulink model.I have read in the provided pdf by the Stm MAT-TARGET that stmcubeide is not well supported by this. So I am using Keil V5. Now after generating the c code from simulink when I opens my keil project , and run the main file nothing happens on my board. I am new to this please guide me. All the c and h files are generated for the respective model in my ide target, but I think the main c file corresponding to the core folder is not linked with the model files.(.c and .h). Please guide me in this regard. Attached are the related files of my project.

Hello, I'm using STML052T8.I'd like to debug while STOP mode on MDK-ARM.How can I set up the MDK-ARM for STOP mode? I'd like to know if there is a caution as this the first time to use MDK-ARM.Thank you in advance.

I've tried solutions given in other blog posts on this topic but none of them worked:using only Java RE 8reinstalling CubeMXremoving non-ASCII characters from my file pathI'm on CubeMX v6.0.1, Java RE 8 and Keil μVersion 5. Any help would be appreciated!

Hello,I'm using IAR 6.21. I'm trying to build a static library but even if my sources didn't change, the binary file is different each time I build again the lib.I tried to compare the lib.a, there is some UNIX timestamps in the file that depends on the build time.Do you know a way to prevent that? I need to have the exact same binary for the exact same sources...Thank you,Charles

Hi There,the goal is to get data from an MCU via I2C to a Raspberry Pi. I already have this working with ATMegas but would like to move to the STM32 Platfrom.Seems I'm quite spoiled as all I needed to get I2C working was this:void sendData(){ byte buffer[32]; for(i = 0; i < 32; i++) { buffer[i] = i; } Wire.write(buffer, 32);   Wire.begin(SLAVE_ADDRESS); Wire.onRequest(sendData);(the buffer would be filled with useful stuff of course).When programming the MCU via the Platform IO the i2cdetect on the RPI detects it - wiring seems okNow I got myself set up with the new CubeIDE, using a SMT32F103C8T6 for now.Got LEDs blinking, yay. Did setup I2C1 for PB6&7 (loving the device configuration tool), set the slave address. Hoping this would be enough to detect it from the RPi.Searching for Examples I started to realize it won't be 2 only 2 lines as I am used to. This is not a problem, the problem is:Where to start? What is the 'propper' way to set up a I2C Slave which shares a bu

When I simulate STM32401RCT6 with IAR，the MCU is on reset state；IAR shows the value of GPIOB register ：ODR=0x00000280；but refer to the reference manual ，the reset value of GPIOx_ODR=0x00000000.Did I do something wrong when simulated?Thanks very much.

I tried to find the frequency that the digital ports of Nucleo-F303k8 can accept data (example: the arduino works with 10kHz on these pins), but i couldn't find anywhere. Someone can help me? I need to use some sensors and I need this information to but them.
