- Is the RJ45 connector a type with built in transformers? Yes the RJ45 connector has built in transformer - Does one of the leds light up when you connect a network cable to e.g. a hub? No none of the leds light Up - Is your hub capable of handling 10 Mhz connections (not only 100 Mhz)? Yes it is c...

Serial Ethernet Schematic
Dear All I tried to work with the schematic specified in the MB help file for SPI Ethernet. The connections seems to be ok, but there is no response from the board. I'm using 10/100 Base RJ45 Connector, PIC16F877A, 8Mhz Crystal. I checked out the schematic for Serial Ethernet board and there's a lot...

Convert Multiple Inputs to One Wire
Dear Friends I have about 120 signals that makes 120 LEDS to glow. Not all LED's will be glowing all the time. Bases on the signals from 120 motors the LED has to glow. In short.... if motor 1 is in ON state the LED-1 will glow. The problem I have is that... the machine that is having the motors is ...

Hello dejan_mrtt and Xor I somehow managed to do it out. But the only problem I have is the flickering that happens. I even tried to reduce the ref voltage, but it keeps on flickering from 26 to 27 and then back to 26, 25 etc.. Is there a way to check if the value holds for some X seconds and if it ...

Dear Dejan Thank you very much for your code and advice. I tried it out, but nothing seems to work it shows a lots of variation even after I take the average of 20 - 40 values. I cant amplify it more using opamp becuase it comes from PT100. I think I have to move to an external 16 bit adc as you sai...

Thank you
Sir Thank you very much for your reply and I understood it. As I said sometimes the output I get on the LCD is 0 , 19 etc.... I'm measuring very small changes (millivolt) but that shows a big variation. Is there any solution to solve this without amplification ? Or If I use PIC16F877 will this issue...

I'm using PIC16F73 for the below program and I'm trying to measure small voltages. The program shows the correct voltage but often it fluctuates.. For eg when measured in the ADC input the Voltage is 0.037 but at the same time the text I get on the LCD is 00025 , 000022 , 00019 etc. The question is ...

Throw away a few digits
dim rrrr as float dim CurrentValue as float dim text as chat[10] CurrentValue = ADC_read(2) rrrr = CurrentValue*(5000.0/1024.0) CurrentValue = rrrr wordtoStr(CurrentValue,Text) Lcd_Out(1,1,Text) The result I get in the LCD is something line 03535 , 02123 etc....... Since Pic has higher accuracy the...

hi copynpaste
I started learning some stuff long ago and I stopped it since I had some exams and I'm back to it again that's y i said that I'm a begineer. Here is what I did To make the adconLCD2 program in the examples folder for PIC16F877 work with PIC16F73 I modified the code as follows and it worked fine. :D ...

I'm tired of trying up with the seven segment. I tried using PIC 16F72 with the ADC on LCD example. Everything seems to be ok. But the analog voltage displayed is too low when compared with the original. i.e the voltage I read on the LCD is 1.25 but when I measure it it shows 4.xx. Is there any modi...

hi
Thanks for your reply guys and extremly sorry for posting threads. The reason is that I'm a begineer and I'm quite curious to know what that exactly means. I posted this after I a long time since I was searching over the internet.
