Hi,

Thanks for the reply.

The idea is that I want to concatenate the token that contains the (.) period char. regardless of what language that I use!

Hi,

I want to write a macro that performs the following:

#define PORT_PIN(__x,__y) __x##.F##__y

so, when calling it with:

#define LEDS PORTB
#define LED1 0
PORT_PIN(LED ...

Hi,

Can anyone help me how to connect this HM2007P with a PIC?

And what kind of PIC should I use (P16F877A, P18F452, P18F4550, or else)?

Thanks

Hi,

I'm currently using this schema, also I will use its analog value.

In PIC,
I made the port A as analog, and I tested it and it works, I don't want the converted digital value, I just want 0 ...

guys,

i found a solution that works for me:

but output is analog, how can I convert it to digital without using the ADC in t ...

Hi,

I've removed the LED and putting 220ohm, so 5v to 220ohm to the anode.
And measured the V between Anode to the ground which is 1.27v

is that correct?

Hi,

Thanks, but here what I have:
1. Sensor OPB705, consists of Diode, a Transistor (Emitter, Collector)
2. A 100ohm connected to 5v, and from this resistor to the anode of the LED, and the cath ...

Hi,

No, I am doing this in real, ignore the name of the components, I've used that device because it has a diode and a transistor, same as my sensor, just to show my sensor's component.

Thanks

Hi again,
Sorry guys, I cannot start this sensor :(, the connection can be shown in the link below, any advice??

As seen in the schema, the Voltage from the first node of 300ohm resistor node is 3 ...

Hi, again

I connected what you've said, but it didn't work, it always return 1, I've used 300 ohm in the diode, and 10k in the collector.

is there any wrong?

I'm using OPB705,

please help ...

Thank you so much, you are good, man.
Just to ensure, is that correct regarding the collector connection?

Thanks, that really helps.

But, can you draw a schema showing the PIC and the sensor, I want to read the distance (not actual distance, just to know if there is an obstacle or not) from the sensor, ...

Hi,

I've recently purchased a reflective sensor (OPB705),
