I am trying to develop a program using the nRFGo kit from Nordic Semiconductor. I built a simple example would turn off LEDs when I pressed a button on the board. I wanted to modify this code such that if I pressed a combination of buttons then a binary representation of the button pressed would be displayed with LEDs on the board. My code compile fine and I can get the code to download into the board but it does not appear to function at all like I intended.
Here is an excerpt from my main.c

mcu int function
void mcu_init(void) { P0 = 0; // Port setup P0DIR = P0_SETUP; //0xF0; // P0.0 - P0.3 output LEDS // P0.4 - P0.7 inputs BUTTONS P0CON = 0; P1 = 0; // Port setup P1DIR = P1_SETUP; P1CON = 0; RFCKEN = 1; // enable L01 clock RF = 1; // enable RF interrupt }
I am trying to turn on one LED on PORT0 and 3 on PORT1, but only one of the LEDs will only light up when I download the code to the board. If I turn off power and turn it back on, none of the LEDs will come on.
Does anyone have any suggestions? Thanks for the help.
I can't see the definitions of P0_SETUP, P1_SETUP.
By the way - your code can shrink a lot if you compute a number and then use the individual bits of that number to control the leds.
LED0 on if (button_value & 1) != 0; LED1 on if (button_value & 2) != 0; LED2 on if (button_value & 4) != 0; LED3 on if (button_value & 8) != 0;
Sorry I forgot that I did not add the P0_SETUP and P1_SETUP.
#define P0_SETUP 0x8C // P0.2, P0.3, P0.7 as inputs BUTTONS #define P1_SETUP 0x71 // P1.0, P1.4, P1.5, P1.6 inputs BUTTONS
Do I need to be doing something different with P0CON and P1CON registers? Thanks for the code reduction suggestion. I will try it.
Does anyone have a schematic for the nRFGo Motherboard? I had a programming adapter built that has flying leads on one end and pogo pins on the other end that will get attached to test points on my prototype boards. I have attached my flying leads to what I assume are the appropriate header pins on the nRFGo Motherboard but when I try to program the board it fails.
My Programming adapter supplies the following connections: FSCK PROG FMOSI FMISO FCSN VCC GND
I took one of nRFGo Motherboards and pulled the LE1 board off and then took the wires for my programming adapter and connected them in the following manner: (I am trying to program the 32 pin part) P0.5 FSCK Pin 25 of Mod A PROG P0.7 FMOSI P1.0 FMISO P1.1 FCSN Pin 2 of Mod A VCC Gnd pin of one of the header strips GND
Anyone have any thoughts or suggestions as to how I can program my prototype boards using the nRFGo Motherboards or any other manner? Thanks for the help.

Errrm... how about Nordic Semiconductor, then?!
I have tried Nordic. Just thought I'd try the forum as well.
I figured out why I could not get the P1 port to work properly on the LE1. If using uVision to program the board, the correct device needs to be selected as well as making sure debugging is disabled.
In uVision go to Flash -> Configure Flash Tools. Up pops an options menu, select Utilities tab.
Make sure it says, nRFProbe Keil Driver. Click on Settings.
Select device (mine is 32 pin device), and deselect Enable Debugging.
Then compile the code, and flash the device. It works perfectly now.
Now I need to figure out how to get the firmware off of the nRFGo motherboard and onto my prototype boards...
I should have read all of the documentation over again. I looked at nRFgo Starter Kit User's Guide V1.1 and found in section 2.1.10 the information that I needed for In circuit Programming. In this section there is detailed figure which shows the pin out for a ISP interface. I attached my pogo pin programming adapter to these pins and using nRFgo Studio, I was able to program my prototype board. I guess that proves that you need to reread all of the documentation a couple times to make sure you don't miss anything.
