comment: Like a dog with a bone, I'm back.Think I've found the OEM of the module. http://www.emartee.com/product/42059/ appears to be it.I've downloaded the schematic and pictures.It does show a real ...

comment: Well I checked your drivers vs mine and they are the same except for the order of the variables.
I chose to do this...
void ds1307_get_date_time(BYTE &yer, BYTE &mth, BYTE &day, ...

comment: Well I'm at a loss to explain why you've lost the day data. I'm even using your fprintf to the PC to view the data on Realterm and it's 100% right, even after yanking off the power for 10 min ...

comment: on my Terminal Window I get 45:85:85-45/25/-1
45:85:85 looks familiar! Have you got the proper I2C bus pullup resistors? With 5 Volts I use 4k7, in fact have a 46k22 using ds1307 in front ...

Try using force_hw on the I2C, and see if anything changes.

Also explicitly set the I2C clock rate to 'SLOW' (the chip only supports this). With your CPU clock it is unlikely that there is a speed ...

Post your complete test program that calls the ds1307 driver functions.
I.e., post the #include line for the PIC, #fuses, #use delay, etc. Post your variable declarations. In other words, post th ...

Hello!
I use this DS1307 driver

Several things needed for -ve.

1) You'd have to add an ability to display '-' to your display.
2) Test if the temperature number is -ve before converting to digits. If is is turn on the -ve in the ...

The approach is flawed in a number of ways:

The interrupt is called every 65536 processor cycles (256*256) = 15 times per second.

Great! Display don't blink!
But now I have another problem. ...

Would you care to:-

1) Show a schematic
2) Provide code which is complete and compilable.
3) Explain how you think the display works.

Hello everybody!
I use PIC16F877A, 4-digits 7-segment display, DS18B20 temp sensor.
My program compiles successfully, display on my real hardware show current temperature.
But it blinks. I think, I ...

CCS provides tested code to send text via RS232.
Use theirs, rather that write your own.

Mike
I try this
void main() {
while(TRUE) {
putc(getc()& ...

Try sending plain text to confirm that terminal and PIC are talking at the same baud rate.

You don't have a #FUSES HS or similar.

I try this
#include <16f877a.h>
#device *=16
#u ...

idea #1
you specify a stream in the RS232 setup but don't specify it in the fputc send.

suggest remove "stream' and try again.

The same. I have "C0" in hex, "11000000" ...

Hello everybody!
I use simple program to understand, how rs232 works.
#include <16f877a.h>
#device *=16
#use delay(clock=20000000)
