Roboard Simple Example of Digital IO

Thanks very much! That was exactly the example I was looking for. Now I just have to build the roboio.lib for MSDEV 6.0! It seems to be fighting me with the various DEFS needed. right now it has initialize errors.

Code:: #include #include int main() { int val; roboio_SetRBVer(RB_100); // set the RoBoard version // roboio_SetRBVer(RB_110); // use this instead if your RoBoard is RB-110 // use all PWM channels as GPIO channels if (rcservo_Initialize(RCSERVO_USENOCHANNEL) == false) { printf("ERR: rcservo_Initialize() fails (%s)!\n", roboio_GetErrMsg()); return -1; } printf("out logic 1 on PWM channel 0 (pin: S1)\n"); rcservo_Outp(0, 1); getchar(); printf("out logic 0 on PWM channel 0 (pin: S1)\n"); rcservo_Outp(0, 0); getchar(); printf("read digital input from PWM channel 1 (pin: S2)\n"); val = rcservo_Inp(1); printf("the value of digital input is %d\n", val); getchar(); rcservo_Close(); return 0; }

Roboard Simple Example of Digital IO

2010-08-04T02:27:09+01:00

I have the Roboard, loaded the OS, have MS development studio and a pretty good programmer. However, all the examples I find for the Roboard are to control a complex organization of Servos (Play, replay, etc).

Does anyone have the simplest main() loop code example minimum which can designate a pin for digital input and a pin for digital output? From that I should be able to program till the late hours of the night.

The available downloads (that I have found) from the Roboard site all deal with PWM/Servos.

I have done a lot of programming in various languages and using various processors (embedded or other) but seem to have a hard time finding the examples to get going on this new project of mine.
