I am currently writing code for a project, specifically interfacing with sensors via an STM32 Nucleo F411RE board. I set the pins/peripherals etc. using STM32CubeMX, then generated the code with the Makefile toolchain for programming in Visual Studio Code. Everything is compiling fine, but the IDE/Intellisense for some reason doesn't pick up any use of uint32_t; any occurences are red-squiggled, with the error reading variable "uint32_t" is not a type name.

I have #include <stdint.h> at the top, and uint16_t and uint8_t are both recognized in the same file. Peeking the definition of those reveals their lines in stdint.h, while the same does not work for uint32_t. I have attempted the solutions suggested here and here, neither of which worked.

I am working in C11 (not c++, which isn't an option for my project) on Windows, here is my c_cpp_properties.json file (with all the extra defines cut out for compactness):

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "databaseFilename": "${workspaceFolder}/.vscode/browse.vc.db",
            "windowsSdkVersion": "10.0.17763.0",
            "compilerPath": "C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.16.27023/bin/Hostx64/x64/cl.exe",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x64",
            "compileCommands": "${workspaceFolder}/compile_commands.json"
        }
    ],
    "version": 4
}

Here is <stdint.h> - all types are clearly declared together, with no apparent condition for uint32_t:

Both uint_fast16_t and uint_fast32_t have no problems when I use them, which rules out type being an issue - they are both unsigned int, the same as uint32_t.

EDIT: While making an MCVE, I narrowed the problem down to #include-ing "stm32f4xx_hal.h" - without this #include, a uint32_t declares fine. Here is a file that demonstrates the problem (changing the order of the includes does not make a difference):

#pragma once

#include <stdint.h>
#include "stm32f4xx_hal.h"

#define MA302_READ_MASK 0x4000
#define MA302_WRITE_MASK 0x8000
#define MA302_ADDRESS_MASK 0x1F
#define MA302_READ_BLANK_VALUE 0x0000

typedef struct {
    uint32_t tester; // 'variable "uint32_t" is not a type name"'
    uint16_t current_raw_16; // declares fine
    uint8_t current_raw_8; // declares fine
    float current_angle;
} ma302gq_p_t;

uint8_t ma302_read_register(SPI_HandleTypeDef *hndlr, uint8_t address);
float ma302_get_angle(SPI_HandleTypeDef *hndlr);
float ma302_raw_to_degrees(uint8_t raw_bit_size, uint16_t raw_angle);
void ma302_init(SPI_HandleTypeDef *hndlr);

"stm32f4xx_hal.h" is part of the code generated by STM32CubeMX, and itself #includes "stm32f4xx_hal_conf.h". Adding #include <stdint.h> to "stm32f4xx_hal.h" allows uint32_ts to temporarily declare in that file; however, switching to the above file and back in VSCode causes the declaration to glitch, and when hovered over, show <error-type> uint32_t

EDIT 2: Here is the first problem file; I didn't include it before as it is automatically generated. "stm32f4xx_hal.h":

STM has a huge web of files all #include-ing each other, there's only so much I can put in one post. Anyone with STM32CubeMX and VSCode should be able to replicate this.

    If you already have looked in the <stdint.h> header file for the uint8_t and uint16_t types, why not keep reading the file to see if you can find out under what conditions the uint32_t type is defined?

  • There don't appear to be any conditions; all uint types are simply typedef-ed unconditionally in <stdint.h>. Some posts referenced some things that needed to be #defined-ed, as in the solutions I mentioned, but adding these made no difference.

    Does Microsoft's c compiler even support c11? Does it support embedded ARM targets?

    Since the problem only occurs when the header file: stm32f4xx_hal.h is included, so we need to see the contents of that file

The stm32f4xx_hal.h header will mess with your stdint.h types if you have not defined your MCU in the vscode workspace. In c_cpp_properties.json, make sure you include:

"defines": [
    "STM32F411xx", // (or whatever your makefile defines)
    (...)
],

  • Thank you so much! I spent ages and I could not figure out what was causing the problem. This solved my problem 100%.

    How do I determine what my generic device name is? I'm using a STM32L476QEI6TR, and I see references to STM32L4xx_HAL_H, so I'm assuming STM32L4xx but that doesn't work.

  • You can check MCU GCC Compiler settings in Cube IDE under Project Properties menu in c/c++ build section. Look for the "gcc" command option, it contains actual mcu name as parameter. Another way to catch it is from verbose build output menu. Or just create empty Cube MX project for the same MCU and generate makefile that will eventually contain the name.

New answer from vscode-cpptools issue. The same problem as mentioned by @vxhht: some STM32 library mass up the stdint.h. But it is not caused by missing MCU definition:

It's not a bug -- in core_cm3.h, it needs to have a compiler define set, such as __CC_ARM or it hits a "#error Unknown compiler".

So add __CC_ARM to defines section of c_cpp_properties.json solve the problem.

all you need to do is:

  1. define your microcontroller
  2. define USE_HAL_DRIVER
  3. define your compiler __CC_ARM

in cpp_properties.json file enter image description here

Oddly uint8_t and unit16_t types for declarations in Visual Studio 2019 C++14 are fine, but uint32_t is not. All these types are fine for IAR compiler cross compiled for STM32F413. But goal is to unit test the target code with Boost Test on Visual Studio C++. Preprocessor symbol STM32F413xx was added to Visual Studio project but did not improve situation. It is true comment out the stm32f4*.h and #include <stdint.h> is fine for uint32_t but must have the stm32f4*.h headers to BoostTest target code though #ifdef out hardware accesses. Previous answer does not say how stm32f4xx_hal.h messes with uint32_t.
