I have a sensor which send LIN message to vehicle, I want to read value of current, voltage, etc, form this message by SMT32. I connect LIN Wire to IO of MCU. How can I connect and analyze data?

Using an STM32H723 I started with a non interrupt USART connection onto a wifi module.I set up the connection on UART3 implementing nothing more than that and using these instructions  int len = sprintf(tx_buff,"AT+GMR\r\n");HAL_UART_Transmit(&huart3,tx_buff,len,100); Followed up with polling instructions to capture the data. if( USART3->ISR & UART_IT_RXNE ){rec1_buff[reccount] = USART3->RDR;reccount++;}Now the above works so now I wanted to do this using interrupts.I then set the interrupt and used the above transmit instruction but no receive packets are ever returned.I have a workaround I put the same receive instructions in a standard timer interrupt and capture the data so I have a solution that works for me. Systick is too slow but I can set a really fast timer interrupt instead for capture. I am puzzled why no packets are returned and the interrupt handler (I just put a breakpoint in the handler) never fires at all. Any advice on this

Hi I'm KIM from south Korea. My MCU is "STM32H735ZGT6". I want to change the clock of ADC1 within the code.I set up the clock of ADC1 in CUBEMX Clock Configuration about 80Mhz, but I want the clock of ADC1 about 75Mhz. How can I change the clock? Thank you.

This should be simple, but I can't find documentation.   I am running an STM32L4P5 at max clock speed (120 MHz), and I have moved all code to SRAM so it is running with zero wait states.    I have an extensive calculation to do using the FPU -- I am optimizing retained constants and such in the FPU registers.  I am wondering if any of the FPU instructions take longer than a single clock tick to execute.   Divide?  Square root?  Are there any inserted wait states?If there is a solid answer and it is in the documentation, please point to where it is docced.    Thanks!

Hi ST, can you please look into this link STM32CubeProgrammer & STM32CubeMonitor support SEGGER's J-Linksand let us know which version of the cube programmer support jlink. A.Satt

We transitioned from BLUENRG-M0L to BLUENRG-M2SP. We did some basic application testing with the X-NUCLEO-BNRG2A1 platform, and we had the example application up and running seamlessly.However, we’ve encountered an issue when integrating the BLUENRG-M2SP with our existing boards. I’m having trouble running the example application. The module and the main controller talk via SPI. While going through the data sheet, I discovered that the BLUENRG-M2SP module must be in Mode “100” pin configuration to be able to talk via SPI with our main controller. Question:Does the module come in “MODE 100” out of the package or is this something we must do at our end. Any clarity on the topic would help us a lot.  

Hello Team,  We want to develop a BDLC driver with high power. We went through the below product, it matches other requirements except for output current, it is only up to 1.5AMotor Control Nucleo Pack with NUCLEO-G431RB and X-NUCLEO-IHM16M1can u suggest a similar module that can support high voltage of up to 60V and a current of up to 20A.it should be able to operate sensored and sensorless  and also on encoder feedback. Regards,Sayali 

In the reference Manual of STMH730, on Table 543, page 2825, there's a Port "ETH_PHY_INTN" listed. Where ist that port? Or where can I configure the GPIO to use for it? I cannot find anything in the datasheet.

Hello,    I am trying to better understand the relation of how the SYSCFG_EXTICRx and the EXTI_RTSR1 registers correspond. In the manual as I understand, the SYSCFG_EXTICRx registers are used to setup a pin on the EXTI line for interrupt use by setting your desired port config. Looking in the manual at the EXTI_RTSR1 register, I believe the 0-15 bits are used for the corresponding lines that the SYSCFG_EXTICRx register sets. However, there is bits 16-21 which if anyone knows what or how they are used?       Any clarification would be appreciated. I am just trying to clarify my understanding is correct and what these other bits are referring to. Thanks

Hi, i have a custom board with a STM32 and a Touchscreen.The TSC is connected via I2C to the STM32.There are other I2C slave devices connected to this I2C bus, as well.And i have two threads, a system thread and a gui thread (where Touch GFX is running in). So when a Touch is detected, the TSC is firing an interrupt and the TSC driver is reading the TSC registers.But when i do this TSC driver stuff in a TouchController class it is executed in the gui thread, right?So when in the system thread are I2C accesses to other I2C slaves, too, sooner or later a collision will occur.So the only way to deal with this as i see it is:- ISR of TSC sets a flag bTouchEvent- in the system thead is:  {    if (bTouchEvent)    {       Read_Out_TSC_via I2c();   }  do_other_I2C_device_stuff }-  Driver Instance of TouchController just reads a structure where Read_Out_TSC_via I2c() stored the touch. No I2C acce

I have a question when I read the reference manual of STM32F405, and it says that "for odd values of RCR, if  the RCR was written before starting the counter, the UEV occurs on the overflow (which should be underflow  as I have seen in TIMx_RCR function description from STM32F103 to ST... - STMicroelectronics Community)And the reference says that  any write to the TIMx_RCR register is not taken in account until the next repetition update event . So my question is in center aligned mode if it is the first time we write the RCR after starting the counter and when will the first UEV happened ?

[EDIT: S'OK, I need to think about this more, but I can't find a way to delete a message so am just marking this as one to ignore]I am just moving from STM32F4 to STM32U5.  ThreadX seems to be the thing for STM32U5 (if one doesn't want to use Zephyr) but I need to be able to use FreeRTOS also, so I have moved all of my code to CMSIS (V2).  However, I am not able to find cmsis_os.h/cmsis_os2.h for ThreadX.  For instance, in the STM32F4 case the CMSIS API for FreeRTOS can be found under the Middlewares/Third_Party/FreeRTOS/Source directory.The STM32CubeU5 only contains "template" cmsis_os.h/cmsis_os2.h files but I don't want a template of my RTOS interface, I want the actual RTOS interface that ThreadX will abide by.  The cmsis_rtos_threadx directory of STM32CubeU5 only contains the .c file, no headers. The ThreadX repo doesn't contain a CMSIS adaptation at all.Where do I find the CMSIS adaptation API that ThreadX will abide by?

I have generated code for STm32U5G9J-DK2 via cubeMX, included FreeRTOS and touchGFX designer middleware. Once I compile I get error "sorry, unimplemented: Thumb-1 hard-float VFP ABI" from multiple locations (total 29 errors). I ma not sure what I am missing or the root cause of these errors.Need help with it. Thank you.

Hello,I'm new to STM32 MCU and have just started learning about them. I want to interface the PS2 keyboard with the NUCLEO-F446RE board. I don't know what hardware will I require to do it. Will I be requiring any adapter board for it?Please help me.

Hi,Run from CubeIDE had not seen any issues until yesterday, but since then I can't run from CubeIDE, and don't know why.Download in CubeProgrammer is OK. I found if I do a mass erase on full chip in CubeProgrammer, then I can run once in CubeIDE. This is the error message:RegardsChao

Dear ST Community,   I need to use an SRAM with the STM32H743AII6 MCU. When I try to configure the project on CubeMX, a warning appears next to the FMC line. I feel like I should fix this before going further with the configuration. I am curious why I am getting this warning even when FMC is the only peripheral that was already configured. Has anybody experienced this before? Are there any suggestions to resolve this? Here is a summary as background information: The warning text says "Partly disabled conflict with FMC Chip Select NE1". Warning stays even if I use NE 2/3/4. The package is UFBGA169, and NE1 pin is available on that specific pinout. CubeMX version is 6.11.0 but the issue was present with earlier versions as well. A screenshot is attached below. Thanks, JD

Hi,Hope this is a simple question.I use this device: STM32H753ZIT6I don't intend to use USB so looked in the datasheet and found the belowDoes that mean I can safely connect VDD33USB to GND?Thank you. 

Dear experts,  I have worked with the SPI of  SPC563 without any problem before. Also, I checked the example of the SPC564 and I am not seeing any differences. now I am trying to config the SPI of a SPC564A70 myself. When I monitored the chip select pin with osciloscope, I saw that the logic of CS pin is inverted. meaning that it is low all the time and when I send the message it becomes high. I also checked the inactive state of the pin in configurations and all of them are "inactive high". can you help me regarding this issue? Thank you

Hi Everyone, I'm working with a SPC570S discovery board. I uploaded a code with my SPC5-UDESTK debugger and the codes were successfully uploaded. But suddenly I couldn't upload any code using that, and its green LED still works. But I tested the same code with another similar SPC5-UDESTK debugger and it worked. I checked my SPC5-UDESTK debugger with other development boards also. Unfortunately, it is not working but its green LED is working. Please help me to sort this issue out.Thanks Yohan 

Good Day,I've been experimenting with transitions on TouchGFX. I'm not a huge fan of the 1990's style transitions that come out of the box, and wondered if I could define a transition myself with custom behavior. Basically, I want sections of my screen to slide off in different directions before going to the next screen.Using the transitions already defined as an example, I was able to use the Snapshot widget to do what I want to do, but I'm currently unable to compile, as the transitions that come with designer are declared in `FrontEndApplictionBase` which is generated code.I guess I'm not looking for a hard and fast solution here, but more just asking the open-ended question of, "has anyone else tried/succeeded in doing something like this?" I'm also open to suggestions of better solutions, but I really like the idea of this clean implementation.Thanks,Jack

Hello! I bought the development board for SPC560B! When using SPC5STUDIO programming software, I found that I don't know how many functions defined in C language are defined! I just want to ask if you have explanations for the initialization definitions of functions such as clocks, SPI, interrupts, etc., so that I can understand them better! Also, is there any documentation and a summary of common problems related to the programming software SPC5STUDIO that I would like to learn and use!Thank you!

hi community,can I use  "SPC5-UDESTK-PLUS" for flashing and debugging for "AEK-AUD-C1D9031", which contain"SPC582B60E1" microcontroller. Regards,Shiva

Hi all,I'm trying add FPU exception to my project and I'm bit confused because two sources points two different interrupt vectors for this. Book E says, FPU exception is under IVOR33 but SPC58xH manual points IVOR10. And SPC5Studio libraries have "decrementer support" under IVOR10. I suspect SPC58xH is right for me but I want to be sure.  regardsMichal
