PCA10000 Tx

I just got stung by this too.

Turns out I have an earlier version of the PCA10000 board. Check your board to see if you have V1.0 like I do. If so, this fix is easy... once you know anyway.

Go to Includes/boards/pca10000.h. There is an #if /#else construct for selecting between board versions. Change to #if 0 for V1.0 and away you go.

In the EK_User_Guide, Page 24, the Development Dongle v2.0 UART lines are connected to pins P0.08 to P0.11 as shown in Table 5. The actual problem is the pins changed.

I have the same problem, but I tried using Docklite and example: uart_example. When I connect board pca10000, and run example for that board, Docklite screen is empty. When pca10000 is connected and used example for pca10001 everything works just fine. Then I tried copying pca10001 main code into pca10000 main code, but the mistake has been retained. Program stops at:

uart_start();

and in there:

simple_uart_putstring((const uint8_t *)" \n\rStart: ");

simple_uart_put(ch);

also here it stays forever:

void simple_uart_put(uint8_t cr)
{
  NRF_UART0->TXD = (uint8_t)cr;

  while (NRF_UART0->EVENTS_TXDRDY!=1)
  {
    // Wait for TXD data to be sent
  }

  NRF_UART0->EVENTS_TXDRDY=0;
}

During this changes (between examples for pca10000 and pca10001) I haven't connected and disconnected little board, so I think that COM ports haven't changed).

Also example: led_radio_example, doesn't work. I think the main problem is with uart communication at pca10000. First mission is to understand why doesn't UART work with example for pca10000, but it's working with pca10001? Also when I connect pca10001 and run matching uart_example everything works just fine.

Thanks for reply. I have tried the sample code "uart_example" with PCA10001 and it works. I suppose the COM ports would be available.

Try checking the COM ports available... I had a similar problem and it turned out to be a question of drivers!

Best of luck...
