I have stripped out the internals of a phone charger power supply for a one-off product of mine - obviously not an option if you want a mass production production. Just an option?

I think one terminal is connected to a pull up resistor and then sensed by the on board Atmel Microcontroller and the other terminal is ground. Dan

A pull-up resistor is often used to detect a burn ...

OK I can see what you are trying to do - but I also foresee lots of problems.

I take it the 'reverse line' is what brings on the reversing lamps and klaxon when the lorry is reversing?
So you are ...

i've just tried your code with a 16F876A and a SHT11.
it's working fine, i've just got 28°C instead of 25°C i guess it's normal (tolerency).

I have been bitten by this one myself recently. I [spam] ...

Well, now I've heavily modified the code that I was given to begin with, and it turns out that I think our flash is bad :-/

Anyone with experience with these modules? I'm getting a constant 36 mA ...

I can think of a way using a 6 pin header and a DPDT switch - but I have not tried it.
It also depends upon what your MCLR pins are connected to.

The pinout for ICSP is as follows:
1 Vpp
2 Vcc
...

I may be missing something here, but what happens if you enter this code with a value of 0x0F?

// here starts the rewritten part
if ( (data2 & 0x0F)==0x0F) // lowest nibb ...

OK there are a number of things wrong here.

In my circuit i have connected switch to pin no. 4 and LED at pin no. 5 And using internal MCLR.
and
But sometimes the microcontroller not reseting ...

INT_RA refers to a digital change on the input pin - not analogue.

#define MODBUS_SERIAL_INT_SOURCE MODBUS_INT_RDA
#define MODBUS_SERIAL_TX_PIN PIN_B0 // Data transmit pin
#define MODBUS_SERIAL_RX_PIN PIN_B1 // Data receive pin

Tx is on the wrong pin to ...

Hmm two posters with the same problem - must be homework time!

delay_ms(1000), will not work as you have found out.
You can only use delay_ms() with a 'variable' with a value of upto 255. I sugges ...

Sorry I was having a bad day yesterday.

What confused me was the fact that the 16F677 shared a data sheet with other devices which did have .h files in v3.249. I should have read Appendix A in the ...

I was hoping to start a new design using the PIC 16F677, however the .h file is missing from my copies of PCM v3.246, v3.248 and the final v3.249? Whilst I await a reply from CCS - anyone got any brig ...

One way around this type of problem is to read the analogue voltage of the digital input, then compare the analogue reading with the expected equivalent logic high/low digital value.
