Hi guys,
I am trying to understand the ports of stm8s105c6..
I want to blink the led1 of the board on port PD0..
For what I understand I need to configure PD0 as Output, and after, drive current to the logic on front of portD0, configuring it as push pull low...
I don't like to mess with STD Libraries for now, so,
// Configure pins
PD_DDR = 0x01;//output
PD_CR1 = 0x01;//push-pull
PD_CR2 &= 0xfe;//Speed of port configured to max 2MHz
// Loop
do {
PD_ODR ^= 0x01;
for(d = 0; d < 29000; d++) {//nothing to do, only burning cycles :S
}
} while(1);
it seems that I have configured it to output push pull...but How to configure push pull low?
By push Pull low, you mean PD_ODR = 0x01, and by high PD_ODR = 0x00 ??
thanks in advnce.
regards
tux
