    • RE: How to scale with display.drawJpg?

      Thanks,
      Indeed,
      This works :
      display.drawJpg(JPG_buffer_processed, Append_this_Struct.JPG_size, 0, 0, Append_this_Struct.JPG_width,Append_this_Struct.JPG_height,0,0,JPEG_DIV_2);

    • How to scale with display.drawJpg?

      I know this is not completely the right topic.
      Anyway,
      I want to scale my jpg, lets say to half its size. I am trying to understand the syntax, but no luck.
      This is what I use :
      display.drawJpg(JPG_buffer_processed, Append_this_Struct.JPG_size, 0, 0, Append_this_Struct.JPG_width,Append_this_Struct.JPG_height, 1.0f, 0.5f)
      assuming the last two floats are a scale factor.
      But my jpg stays the same size.
      Anyone any idea how to scale my jpg ?
      thanks

    • RE: SIM7080G CAT-M/NB-IoT+GNSS Unit Issues

      #include <HardwareSerial.h>
      HardwareSerial Comm(1);

      Comm.begin(115200, SERIAL_8N1,TX_pin,RX_pin); // TX RX

      Comm.print("AT+IPR=115200\r"); // Set text mode

      Last command should return an OK. If not, it could be that you have mixed up TX and RX pins or a power issue.

      To read the reply from the module you could use something like this :
      while (millis()<wait_until)
      {
      while (Comm.available())
      {
      ccc=Comm.read();
      //Serial.print(ccc);
      if (k<buffer_size-1)
      {
      Receive_buffer[k]=ccc;
      k++;
      }
      }
      Receive_buffer[k]=NULL;
      if (strstr(Receive_buffer,StopCharArray)!=NULL)
      {
      //Serial.println("OK found");
      // SIM7600_Error=0;
      Receive_buffer[k]=NULL;
      return false;
      }
      }

      You may also try to remove the simlock of your card.

    • RE: M5paper void disableEXTPower()

      @felmue But that is great. That means that I can turn off the SIM7080 module during sleep mode. Ha Ha. (this topic was also addressed in another threat).
      Btw I now also read the M5EPD.h and schematic and understand your explanation. Thanks.
