Solved

When I setup the UART i activated both DMA TX and RX, and I turned on the UART Interrupt in the MX program. Looking at the code in stm32f4xx_hal_uart.h Around line 680/* Callbacks Register/UnRegister functions ***********************************/#if (USE_HAL_UART_REGISTER_CALLBACKS == 1)HAL_StatusTypeDef HAL_UART_RegisterCallback(UART_HandleTypeDef *huart, HAL_UART_CallbackIDTypeDef CallbackID, pUART_CallbackTypeDef pCallback);HAL_StatusTypeDef HAL_UART_UnRegisterCallback(UART_HandleTypeDef *huart, HAL_UART_CallbackIDTypeDef CallbackID);#endif /* USE_HAL_UART_REGISTER_CALLBACKS */So how do you do an idle_line interrupt using the HAL? I am using STM32F446.

Posted on April 14, 2017 at 22:44Tried to get this working, no success.HID is OK, virtual COM, MSD, everything works fine.Audio class is recognized as composite device only. I've connected USB DP, DM and GND only. VBUS sensing is OFF.  12 MHz external HSE clock implemented, PLL for usb is generating 48 MHz correctly.I'm on the latest cubeF4 version (1.15.0) and IAR IDE. Any ideas, why it's not working? #stm32 #cubemx-f4 #usb-audio #cubemx

I am designing a sensor board from scratch. It will be similar to evaluation board ..\STM32Cube\Repository\STM32Cube_FW_L4_V1.16.0\Projects\B-L475E-IOT01A.I have tried example projects, they work great. Since ST do not have .ioc files for the this board, I do not know what IDE was used and how the codes were generated with correct configuration and correct driver files in the correct directory structure.I tried recreating a project with this board (using CubeMX ) and adding one component only from It created the project with this structureIt builds without any errors. So far so good.Now I want to copy just one function from the example such as while (1) {    Temperature_Test(); }This code will look for the associated driver files, API and other supporting configuration codes.Can someone guide me or show me a procedure to identify the files with their locations and copy them to relevant directory and also paste the codes (with any changes if necessary)

I've gone through AN2594 and the associated examples. They're all for the standard peripheral library which is now deprecated.Someone has an example of a port on github that looks reasonably complete https://github.com/lamik/EEPROM-emulation-STM32F1-HAL/blob/master/Src/eeprom.c and at this stage it looks like I will be using thathowever...I'm wondering it ST have (or are planning to have) an official update?

I have an STM32H743 connected to a screen that uses ST7789 via FMC (i.e. parallel connection) using 8-bit bandwidth and A18 to select between command and data.The current code has an issue that the screen output is messed up (see pictures below) if I don't add a sleep to my write functions that uses FMC.The code is working (no need for delay) under STM32CubeIDE but I ported it to work as part of MicroPython.Things that I already considered:Python speed - The code in C is a nested for loop and calls writeData so it isn't a python speed thing.System clock/FMC - I copied the whole code of FMC initialization (including Msp), GPIO and systemclock to MicroPYthon without any fix.HAL version - MicroPython uses a different stm32 HAL version but I copied the SRAM/FMC files and it still didn't workAny pointer on what might be the issue? Is it a FMC clock configuration? some configuration on external memory location?Any config that slows down the FMC as RAM accessAppendix:#define COMMAND_LOCATION

I was able to open the ST25R3911B_DISCO_FW's included DISCO-STM32L4x6.uvprojx file. It builds and debugs easily, until... I try to uncomment back in the functions in its main and while (StreamDispatcherInit, ProcessIO and dispatcherWorker), which then promptly breaks Keil's own 32k size limit for the free version.  Well, that'll get the hopeful STM32 newbie seeking an alternative to an expensive Keil uVision license right quick, won't it?  So, I'm trying to drag the code over to STM32CubeIDE and build there, beginning with ST example code in the CubeIDE appropriate to the ST25R3911B-DISCO board's host MCU (an STM32L476).Any best practice for dragging code over from uVision to CubeIDE? Thx.

Hello. For my automotive project I need to imitate motorcycle handlebar that uses LINbus for buttons many buttons. Since I can't always take handle off motorcycle I need to make emulator of it.This is Typical frame, and I mapped all bits of this burst. Brak , sync, ID is by my understanding is generated by master ( ECU ) and data is generated by handlebar controller.Is where any example how to use LINbus? My understanding it should be something like CANBus, I get I whould get IRQ then ID is matched and simply send data just like regular UART message as well as calculate message CRC ? Any information would be welcome. Thank you !

We have designed a custom bootloader solution that works on multiple STM32 devices, however when we attempted to use it on STM32L496VE we realised HAL_FLASHEx_Erase did not clear the flash, even though it returned HAL_OK.On further investigation, it was found that the HAL library assumes any stm32L4xx has 2 banks, with each bank having half the FLASH_SIZE. This meant that FLASH_SIZE is set to 512KB, and FLASH_BANK_SIZE is set to 256KB for STM32L496VE, whereas the datasheet states that this IC has 1 bank of 512KB.Note - we have modified the defines to ensure STM32L496VE has only 1 bank in the HAL Library, however HAL_FLASHEx_Erase still does not work. Potentially the assumption that the device has 2 banks causes a lot of ripples throughout all the other libraries for the same device.Is there any assistance you can provide with this please?Regards,Kaz

Hi,We are currently evaluating the possibility of using the LSM6DSO and LPS22HH with the MotionFD library, to detect when our product has been dropped from height (up to 9 meters).One of our requirements is that the product always monitors for fall events even when the main MCU is off/standby. Seeing as we do not need a real time indication of a fall event (just keeping a log of events), we want to try and utilise the FIFO buffer on the accelerometer to collect data that can retrospectively be passed to the MotionFD algorithm for analysis.According the the MotionFD user guide (https://www.st.com/resource/en/user_manual/dm00427990-getting-started-with-motionfd-realtime-fall-detection-library-in-xcubemems1-expansion-for-stm32cube-stmicroelectronics.pdf), the library requires "accelerometer and pressure sensor data sampling frequency is 25 Hz".Upon review of the LSM6DSO datasheet, it was found that the closest batching data rate that can be used for the FIFO is 26 Hz. Will this mismatch b

Hello everyone,I'm debuging a project with 2 recent commented lines, and the debug is executing this lines: I previously builded that project, I don't understand what's happening, maybe you can answer me that question.Thank you in advance!

Hello,I am using GCC and eclipse CDT. I need to execute an external interrupt very fast (every 4µs). There is not a lot to do in there but I use about 2.5µs of time in the interrupthandler. I tryied to put the handler in to ram wich gave me the relocation truncated to fit: R_ARM_THM_CALL against symbol error. I put the handler into the data section with __attribute__ ((section(".data"))) . The reset handler copies the data section to ram. In the linker the data section is defined with   .data :   {   _data = .;   *(.data)    /* Data memory */   _edata = .;  } >ram AT > romNow my question is what could be wrong. The STM32F103C8 has 20K of RAM. That should be more than enough plus all the variables.Alternative would be to pre cache the interrupt code and keep it in code. Is that possible?When I look at the code execution by toggling a pin it seems the interrupt fires about 900ns after the inte

Hello,I'm using CubeMX with X-CUBE-BLE2 3.1.0 Software Package to generate the SampleApplicationI am generating for my L073RZ-NucleoBoard.The code generated work, but each time I generate, I have to make modification in the generated file Drivers/BSP/STM32L0xx_nucleo.cSo I would like to make the modification in the original file, but I could not find it:STM32Cube_FW_L0_V1.12.0/Drivers/BSP/STM32L0XXNucleo is not the same fileIn X-CUBE-BLE2\3.1.0\Drivers\BSP there is only a L4XX fileSame in X-CUBE-BLE2\3.1.0\Projects\STM32L476RG-Nucleo\Applications\SampleApp\SrcSo, either I am missing the correct location, or maybe MX is using a template, but where is it to modify it to generate the file with my modificationThank you for your help

Assembly of the device is extremely tricky since the terminals are all hidden from view and one can never be sure of the correct alignment. Also the terminal 1 is marked only through a notch on the terminal 1 and the dot on the top surface isnt visible.

Hello everyone,I am trying to setup the clock of my STM32G070KB using a 8MHz external quartz. I tried 2 different ways, one from CUBEIDE, the other from libopencm3. I didn't succeed to make my application work yet. CUBEIDE : I see a warning near the RCC tab in the mx configuration but i can't figure out what is wrong. Here is attached what i see and also the config clock tab. Do you see something wrong ? It seems the HAL code is waiting the HSE to be ready and timeout but i am not sure of it. Also i don't see the MCU is sending pulse to the quartz.libopencm3 : Just use the structure attached and the rcc_clock_setup function (for those that used it). I just want to say that i didn't have any trouble with other MCUs.Thanks for your answer,Best Regards,Thomas

Hiii All,I am new in CMSIS2 RTOS Development .I used STM32F072RB UC. In that I am using CMSIS2 RTOS . I have created two processes, One is for reading the key pressed detection and second is for handling leds according to key pressed and released. How to sent key pressed and released data from one process to another process. my Process one is,void StartDefaultTask(void *argument){ /* Infinite loop */ for(;;) {  for(uint8_t i=0;i<0x0F;i++);     if(0== HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_0))     {   // Want to sent data to another process     }  } /* USER CODE END 5 */}My second process is ,void StartTask02(void *argument){ /* USER CODE BEGIN StartTask02 */ /* Infinite loop */ for(;;) {// If data received from process one then want to toggle the led HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_9);   osDelay(100); } /* USER CODE END StartTask02 */}Y

I am developing a custom bootloader for OTA purposes. I successfully did this under one assumption, that the .bin file is divisible by 4. which means since it is 32 bit even the last part will be inside one full memory cell. Is it correct?

I have just installed SPC5Studio 6.0 and I have opened GTM DPLL Test Application. I am getting the "Unresolved inclusion" error for#include "components.h"#include <build/mcs/mcs0.h>How do I resolve this? I don't seem to have any folders like the ones given for previous versions.

Hello all, I have a problem when I try to use VL53L0X GUI application: it doesn't recognize the NUCLEO-L476RG board. First, I install STSW-LINK007 and STSW-LINK009 as manual says.Then I connect X-NUCLEO-53L0A1 + NUCLEO-L476RG to my USB port, start the application and get the next error: Why is this happening? Does VL53L0X GUI only works with NUCLEO-F401RE but not with NUCLEO-L476RG?Note: I know my NUCLEO-L476RG and my X-NUCLEO-53L0A1 aren't damaged because I can download the VL53L0X examples and they work well: Thanks in advance.Regards.

So I have some tiny stepper motors I've been working with. Very small 8mm tall x 7mm diameter and coil resistance is 40 ohm. We're designing some tiny digitally controlled dial gages around these and wanted to direct drive the needles instead of tiny gear trains. Tested with common stepper driver (non-st part) in 1/32 and was fine - too high current, too high voltage, but worked fine. I figured the STSPIN220 with it's 1/256 microsteps would provide the boost in accuracy and be designed for low voltage battery operation. However in 1/256 mode or any of the higher res (1/128 or 1/64th) it's operation is smooth then jumps, smooth then jumps. It's like it's cogging. So after hours I pulled out a NEMA17... and immediately perfect in 1/256. So I probe the coil and the voltage looks pwm'd sine-wave with the nema 17 but on the tiny motor it's sine-wave like for maybe 1/10th the time and full on. Is there some way to get the STSPIN220 to work with these small motors? Or is this something this d

I am working on the STM32MP157A. Setting PLL in the STM32CubeIDE does not work as expected. 24 MHz HSE DIVM4 = /5 DIVN4 = X84 DIVQ4 = /5 should = 80,460,000 . The MX program says 80,960,039. I do not understand. If the MX program is right, then what is the equation? I am trying to find the right combination to exactly get 460800 baud to work. The numbers I used should have worked.

Having problem on driving a motor with L6470 at speed range around 120 - 300pps where motor vibrates and making buzzing noise ,especially louder at 150 step/s, or mounting on a panel where the whole mechanical piece parts is vibrating together.Already followed the parameter optimization step stated in the application notes AN4144, which is target to optimize the compensation curve so that the current output is stable across the application speed range. However the vibration still happened and the measured current wave showing distortion.I suspect the vibration is due to the resonance frequency of the motor but I already drive it with 128 micro step... Lowering the current and operate beyond the motor's resonance frequency range is not possible to be the solution for my application.Not sure if anyone facing the same problem and could give me any guidance on this? Perhaps someone who experienced on motor can help me to confirm that the root cause is due to resonance frequency of the moto
