Howdy Folks,

i made a maths game for my kid. Pretty simple stuff. Written in c/c++ using the arduino toolchain.

new version of the maths quiz game for my offspring.
new quiz types include:

• 2 levels of multiplication (2, 3, 5, 8, 10 * 1 to 10 and 6, 7, 9, 11, 25 * 1 to 10)
• round a random number to 10 or 100

Hello NYCMS, WOuld you mind pointing me the tutorial or similar you used to get your VSCode and Arduino CLI toolchain working?
Thanks.

It works now, thank you!
(I had forgotten about that option)

i love my 2 cardputers, have been using them to make maths toys for my youngest kid. recently have run into a problem i dont know how to fix.

on a razer laptop on ubuntu using the arduino toolchain i uploaded the following code:

#include "M5Cardputer.h"

typedef void (*thread_t)(); // define a simple type for a function pointer

static int constexpr num_threads = 2;
thread_t threads[num_threads];
thread_t current_thread;

void thread_01() 
{ 
  Serial.println("Thread 01");

  // M5Cardputer.Display.drawString("Thread 01",
  //                               M5Cardputer.Display.width() * 0.25,
  //                             M5Cardputer.Display.height() * 0.25 );

} 

void thread_02() 
{ 
  Serial.println("Thread 02");

  // M5Cardputer.Display.drawString("Thread 02",
  //                               M5Cardputer.Display.width() * 0.75,
  //                             M5Cardputer.Display.height() * 0.75 );

} 

void setup(){

  auto cfg = M5.config();
  M5Cardputer.begin(cfg);
  M5Cardputer.Display.setRotation(1);
  M5Cardputer.Display.setTextColor(GREEN);
  M5Cardputer.Display.setTextDatum(middle_center);
  M5Cardputer.Display.setTextFont(&fonts::FreeSans18pt7b);
  M5Cardputer.Display.setTextSize(1);

  Serial.begin(115200);

  threads[0] = &thread_01;
  threads[1] = &thread_02;

}

void loop() {

  Serial.println("Main Loop");

  M5Cardputer.Display.drawString("Hello",
                                  M5Cardputer.Display.width() / 2,
                                M5Cardputer.Display.height() / 2 );



  for ( int n = 0; n< num_threads; n++) {
    threads[n]();
  }

}

now when i USB power the device it shows Hello in large friendly letters, but will not accept any new serial uploads from the ardulapino ide or from M5Burner. Though I can see the "Main Loop" text in the serial monitor of the IDE.

Does anyone here know how to get back from this predicament?

Thanks,
Sean
