Hi Michael,
Thank you very much for your answer.
Well, there isn't really much source, here we go:
#include <conio.h>
#include <unistd.h>
#include <remote.h>
#include <dsensor.h>
int my_lr_handler(unsigned int etype, unsigned int key) {
cputw(key);
return 1;
}
int main(int argc, char **argv) {
lr_startup();
lr_set_handler(my_lr_handler);
ds_active(&SENSOR_1);
while (!shutdown_requested()) {
lcd_digit(LIGHT_1 / 10);
msleep(200);
}
lr_shutdown();
ds_passive(&SENSOR_1);
return 0;
}
The main program just displays the reading of a light sensor on the right
digit, while the remote handler should display any received key value.
However, when I run this program and press some buttons on the RC, only the
IR indicator flickers.
As the remote control is working for you, I guess I am probably missing
something simple here.
Could you please point me to the right direction?
Regards,
Christian

| (...) I compiled your program and it did everything. No problem on my side. If you don't start your program, does the remote control work? Attach a motor at A, B and C and try to run it with the remote. Or try to run your program with the P1 button. (...) (21 years ago, 28-Jul-03, to lugnet.robotics.rcx.legos)

| Try removing the calls to lr_startup() & lr_shutdown(). I think these already get called outside of your program. (Sorry, don't have time to test right now).
