I use a simple delay clock code. But whenever I use this code program won't start without entering debug mode in KEIL. I plug stlink out and reconnect but it wont work if I don't enter the debug mode. Is there any solution to this. If not then what else…

Hi All,

I am using Keil uVision 5 with STM32F411RE

I have a piece of code as follows (source http://www.keil.com/support/man/docs/armlib/armlib_chr1358938931411.htm)

#include <stdio.h>

struct __FILE
{
    int handle;
};

However, I keep seeing…

I'm using Keil V5.30.0.0 and ArmClang.exe V6.14.

When I tried using std::mt19937, like so:

#include <random>

std::mt19937 mt;
std::uniform_int_distribution< uint32_t > dist(0);

auto a = dist( mt );

I got linker errors:

Hello there. I have a homework to do stopwatch, but I'm having a few problems. 
In code there are 4 button interrupt(B0-B3), 1 timer1 interrupt for 1 ms and USART2 interrupt. 
Buttons and timer interrupts work properly but USART2 interrupt work just…

Hello everyone,

I just started to study ARM this week and i was trying to retarget printf to make it work with UART. After many tries, it just started to work magically as i put the stdin and stdout lines(#16 &17) out of the main function scope. What's…

Hi!

I can simulate ARMv7 assembly code with Keil, however, I cannot simulate ARMv8. Do you know if that is possible?

Many thanks,

Hello. I'm working on a project and I need to take some values from a text file and save them in registers. I've searched in internet but there's not enought information about the set of instructions I must use to read the file. Any ideas? Any basic block…

I'm a beginner to stm32 world, and currently using STM32F407VG and the KEIL version is MDK 5.30. I started with the basic example blinky code. And when I'm trying to flash the code a dialogue box is popping with a message "Command not su…

Hi,

I'm working on a cortex M3 based MCU with Keil. After reset a device related information is stored in R4. This value is cleared after __main and before the main function. Is there a way I can store this value and later read it back somewhere after…

Hi,

I'm using a STM32F4 Discovery board which has a STM32F407VG with a LIS3DSH accelerometer which is connected by SPI. I'm trying to read a register from the accelerometer and I tried writing the address of the register to SPI->DR. But SPI->DR shows…

Hello,

I am trying to find out GPIO mapping on a board with an STM32F407 (which firmware function is related to which GPIO). I know I could do it using a LA, but pins are note very accesible.

I have no access to source code so... I only have a firmware…

Hello, i have an issue that seems to be from the compiler but i am not 100% sure. First of all the project was not made by me, but the company i work bought it from another company. As this project is related to a company i am not able to share many specific…

Hello,

 I have a custom board which is based on the design of the STM32F769I-EVAL. I need to flash the QSPI flash in Keil.

For this reason I need a custom FLM file because the QSPI CS PIN changed from PIN6 to PIN10.

Unfortunately I can't get an algorithm…

Hi all,

One question regarding including a custom FLM file in the Flash Download dialog.

Does the Keil version used to compile the FLM in the first place has any implication on whether or not the FLM can be used in other Keil versions?

I compiled an initial…

Hello. I am trying to start a project with STM32F358VCT6. I selected the MCU in CubeMX and only added one pin as GPIO to start with. When I open the project with Keil and try to compile it, I get this error:
