We are very happy to anounce that most of our new libraries start to work: Led, DigitalIO, DigitalBUS, Serial (to Uart, USB, GDB). With great enhancements over previous versions. You can update your SDK libraries following the tutorial here.

We have also updated the gdb monitor with an small bugfix, and added console output support , now when you compile your code for use with GDB (make GDB=yes on new libraries), the libraries will detect that the Espardino gdbmonitor is running, and it will output all usb serial data to the GDB console, which is much more handy for debugging.

This is an small code example:

#include <micro214x.h>

int main(void)
{
   Led led1(LED1);                // declare led1, connected to led: LED1
   Serial output(USB_TX,USB_RX); // declare the serial connection, USB
   DigitalIO my_output(P0_0)  // declare my_output attached to P0_0
   DigitalIO my_input(P0_1);   // declare my_input, attached to P0_1

   // declare my_bus, in 8bits, connected to P1.24 .. 31
   DigitalBus my_bus(P1_24,P1_25,P1_26,P1_27,P1_28,P1_29,P1_30,P1_31);

   while(1)
   {
      wait(0.5);
      my_output.on();
      led1.on();

      wait(0.5);
      my_output.off();
      led1.off();

      output.printf("my_input=%d, my_bus=%04x\r\n",
                            my_input.read(),my_bus.read());
   }
}

This is the example printing out to GDB, when debugging (compiled with ‘make GDB=yes’)
