Hello
I am a professor of electronics and microcontrollers. Due to covid-19 I can no longer do practical work with my students.
I have PROTEUS ISIS with VSM for ARM.
There are examples on STM32 F401 which work very well.
On the other hand I am unable with the online compiler to compile correctly with the .HEX extension which is recognized by PROTEUS.
I recover the .bin then I create a .hex with the ARM tool
srec_cat.exe a.bin -binary -o a.hex -Intel
I get a .hex, I link it with my PROTEUS scheme, the simulation runs but it doesn’t work.
Can you help me
Hi,
You could use Mbed Studio for compiling. If you modify mbed_app.json and add there line
“target.OUTPUT_EXT” : “hex”,
inside of “target_overrides”: {
Mbed Studio will compile and build .hex file. You can use Mbed Cli as well. And you can add / modify the same mbed_app.json file in Online compiler and it will compile hex-file.
Regards,
Pekka
Hi, Pekka
Thank you for help, I tried your solution without success with mbed studio.
I have the error message

Hello,
I can now have a .hex but program does not work.
When i run it on proteus i can read an error message in terminal
This is my program
#include “mbed.h”
#include “platform/mbed_thread.h”
#include “mbed_trace.h”
#define TRACE_GROUP “main”
// Blinking rate in milliseconds
#define BLINKING_RATE_MS 200
int main()
{
DigitalOut led1(LED1); // Nucleo PA_5
DigitalOut led2(PA_6);
DigitalIn btn(PC_12);
Serial pc(SERIAL_TX, SERIAL_RX); // Nucleo PA_2, PA_3
int cpt=0;
pc.printf(“Hello\n”);
mbed_trace_init();
tr_debug(“message d erreur”);
while (true) {
led1 = !led1;
thread_sleep_for(BLINKING_RATE_MS);
if (!btn) led2=1; else led2=0;
pc.printf(“cpt: %d \n”,++cpt);
}
}
I can see on proteus terminal

Hi, could you please help me with finding the “mbed_app.json” location in the directory?
Hello,
if you not have the mbed_app.json
file in your project folder, you can create one.
