Solved

I would like to implement a FFT on a STM32F103 (blue pill).So far i installed the STM32cubeIDE and set up a project.I added "CMSIS CORE" and "CMSIS DSP" (as library) in the cubeMX software under additional software.In my code i added: #define ARM_MATH_CM3#include "arm_math.h"However, when compiling, i get this error:../Core/Src/main.c:27:10: fatal error: arm_math.h: No such file or directoryWhy that?Is there a step-by-step guide for absolute beginners like me?

I am using STM32F103C8T6 with libopencm3 and FreeRTOS. Some programs I have can only flash once, even though the code function properly. The second time I flash it will say something like "unknown chip id! 0x3748. Failed to connect to target". I have to set boot0 jumper to VDD, and issue "st-flash erase" from console, then set boot0 jumper back to GND to reset the board. My question is: Is this normal? If not, what could be the problem? How can I narrow down the issue? It really is inconvenient to go through so many steps to flash a new code.

I've not been able to find anything that explicitly shows how to use TrueSTUDIO to compile onto a board, how do you do this???

Hi guys, I have a STM32 blue pill and followed instructions from a youtube video which showed me how to program the Blue pill with the Arduino IDE. After doing something I was able to load code on to it but later I wasn't able to. I am using a MacBook Pro and the Arduino is giving me an error message of this- Arduino: 1.8.9 (Mac OS X), Board: "Generic STM32F103C series, STM32F103C8 (20k RAM. 64k Flash), Serial, 72Mhz (Normal), Smallest (default)"Sketch uses 12648 bytes (19%) of program storage space.

I have such dev board and try to run it as virtual com port. I created project cubemx, enable only usb as device in CDC mode. After generating and running project with next small fixes I run it on board.int main(void){//....skip while (1) {   /* USER CODE END WHILE */    const char* str = "Test\n";    CDC_Transmit_FS((uint8_t*)str, 5);    HAL_Delay(1000);   /* USER CODE BEGIN 3 */ }gtkterm connects to the dev but no received and sent data.When I started to debug interrupt handler I found that usb device always in USBD_STATE_DEFAULT mode since start and state isn't being changed instead of ISRs..USBD_StatusTypeDef USBD_LL_SOF(USBD_HandleTypeDef *pdev){ if (pdev->dev_state == USBD_STATE_CONFIGURED) {   if (pdev->pClass->SOF != NULL)   {     pdev->pClass->SOF(pdev);   } } return USB

Now, I am using the NUCLEO-H755ZI-Q board,  Could you share how to solve the issue of using the same (shared) variable in across different cores?when I try to debug the code of freertos ,It is not going to debug after it enter this line  osKernelStart(); how to debug further. how to know my code is correctly working or not. (i am useing stm32cubeIDE)

Can I run a Machine Learning model using Tensor flow lite or Edge Impulse on STM32F103C8T6 with 64kb flash.Actually I don't have any choice but to try to run the ML model on Blue pill, because my there is unavailability of other MCU boards at the institute. Any kind of help would be appreciated !

Hello guys, I want to control 128*64 GLCD(ks0108) with STM32 blue pill.I searched many resources on the internet but I could't find any useful example.How can I use 128*64 GLCD with STM32 MCUs?Could you share library and connection diagram?

When configuring UART on the board, according to https://wiki.st.com/stm32mcu/wiki/Getting_started_with_UART the program can be flashed once. When trying to flash again the system reports:Target no device foundError in initializing ST-LINK device.Reason: No device found on target.This happens even when just the configuration is set, no data transmitted and MS_USART_UARTx_Init() is commented out. The error occurs with every UART. It does not disappear when deleting the UART configuration in the IOC editor and regenerate the code without any references to UART. With BOOT0 set to high, reconnecting to ST-Link and flashing another program without configured UART the board behaves normally again. Commenting out HAL_Init() prevents this error, but I strongly assume that leads to other problems. This only happens to the Bluepill board, testing the same configuration with an STM32F407VGT6 (STM32F4-Discovery and an STM32F401CEU6 (Blackpill) stay inconspicuously. Any ideas how to circumvent this

Hi! people! i have a stm32 blue pill board and the Si4432 module, i want configurate for conect with 433mhz module syn470r in OOK,I already have the SPI configured in STM32CubeIDE and the module connected, but i have no idea how to transmite. How to configurate for 433mhz and OOK. I need help, as iniciate my projet.

I am using CubeIDE to code on my STM32 Blue Pill to display a string on my serial monitor but it is only available on loop. Is there any way to print it on serial monitor once ??And how can I read values from the serial monitor and use as an input value ??

Someone knows this board?With MCU STM32F103C8T6

 I am trying to program STM32 blue-pill board with STM32F103C6T6A  microcontroller and using STM32CUBE IDE. But nothing is able to upload the program to the microcontroller. When trying to upload the program, the following error messages are showing. Is there anyone in this forum? Who has done blue-pill board programming using STM32F103C6T6A  and STM32CUBE IDE before? What is the problem here? How to resolve this problem?Here is my bug report*******************(*)********************************************

I have tried to upload a blink program to a Bluepill (STM32F103C8T6) board through ST-LINK V2 while doing so i get the error as "Target no device found Error in initializing ST-LINK device. Reason: No device found on target." and        "Failed to execute MI command:target remote localhost:61234Error message from debugger back end:localhost:61234: Connection timed out.Failed to execute MI command:target remote localhost:61234Error message from debugger back end:localhost:61234: Connection timed out.localhost:61234: Connection timed out"Could anyone help me out with this problem.

I downloaded the USB boot loader (generic_boot20_pc13.bin) to STM32 Blue pill and I am able to detect the board in Arduino IDE. But when I flash the simple blinky code to board from Arduino IDE, the board looses connection. When USB boot loader is flashed again the board detects. Looks like I am missing something while programming boot loader or application code. Can someone help me on this?

Hi all,This is my first embedded programming project and Blue Pill is my first board to work on. Since I've got some experience in C++, I wish to use that language to make a project for blinking the Blue Pill's LED. Amongst various IDEs out there I picked up STM32CubeIDE because I suppose they both are from a family and they're better to be used together.There are very many tutorials regarding Blinking Blue Pill's LED on the Web, but the problem with all I came across were two things: they all use the C language to program and also a pre-made code for the project. I want to use C++ and write the code myself.After installing the IDE, I created a new STM32 Project called "Blinking LED" and then selected C++ as the target language and I'm stopped there. What I need now is a guidance to conduct me from that point up to the IDE's code editor where I can put my own C++ code for the project to be run on the board.

Hello,i am working for now on a diy project.In this project i am interfacing LoRa SX1278 (SPI), MPU6050 (I2C) and NEO-6M (UART) with the STM32F103C8 (blue pill).All in all it is working but because all this sensors and modules are served in the loop, it is affecting the speed of the µC.I am thinking of using Free RTOS for that purpose.The goal is that every 10 - 15 seconds the STM32 reads  NEO-6M and packs the results in a Buffer to send it with LoRa to the receiver.Would free RTOS be a good idea?Any suggestion is appreciated.Thanks in advance

Hi AllToday I wanted to start working with Bluepill DAC that turn out in STM32CubeIDE there is no DAC peripheral and I was shocked. Does anyone know what the h... is that issue? and how to solve it? I don't like to configure it by myself.

HI!I recently purchased some ST products, attempting to program and debug.I initially purchased a STM32 Blue Pill (STM32f103) along with a Mini St-Link V2 (Clone). Then I purchased an STM32F3VE board.I was able to program both boards using ST-LINKV2 (clone) and CubeProgrammer but not to debug via CubeIde, as I understand ST no longer allows debugging via cloned STlink.Wanting to debug I purchased a STLINK-V3minie, but I can't even connect with the CubeProgrammer Software to both cards. I have checked the connections over and over again and they are correct.I changed the firmware version of the Minie, believe me I've tried them all. I checked with the oscilloscope whether the CLOCK/Data are present, and everything is OK.What do you think about it? Is it possible that the cards have cloned chips and therefore the minie doesn't connect? If, yes, how can I check from CubeProgrammer whether they are genuine ST or not? Looking at the ICs case/mark they look Genuine.Thanks in advance 

I would like to know whether the stm32f103c8t6(Blue pill) can be supplied using a 5v source through the regulator ( 5V pin); I've seen a lot of people indicate that it was possible but the datasheet clearly says that the maximum voltage the regulator can take is 4.0v. In addition, I've read that the regulator is disabled in stop mode, does that mean that I cannot use my external 5v source in while in stop mode? and is the onboard usb regulator the same one used on the 5v pin? ( I've only seen one regulator in the blue pill schematic) Image to see what portion of the datasheet I'm referring to :

Hello!I have Blue Pill board and ST-LINK/V2 programmer. When I open STM32CubeProgrammer on Windows 10, my ST-LINK is detected properly but nothing happens when clicking on connect. No error messages, nothing. I can click all day and nothing. At the same time if I connect my ST-LINK to an Linux machine, STM32CubeProgrammer connects to my Blue pill without any problems. I have found couple of threads on Google with similar issue, but they seem outdated and are not working for me. I have tried re-installing JRE multiple times, but nothing changes. I hope you guys could help me, as I am really willing to start learning STM32.
