Dear members, I'm trying to get the 18F2420 to work in i2c slave mode. Below is my code. I modified it from my working 16f1938 code, yet it does not work on 18F2420 nor on 18F2550. I guess I'm missing some registry setting - although I double checked it - no luck. Help much appreciated! // Lcd pinou...

Hello,

I have PIC18F4620 connected to ENC28J60.
I would like to use my PIC as a simple web CLIENT - it should request "http://192.168.2.10/data.php?v=VALUE"
There are some examples of http server but not a client.

Please advise.
best regards,
pepesz

@Mince-n-Tatties It's not a 'must have' but it can be handy. I'm using the function with 6 arguments, while in most cases only two are needed. If I'm using this function 20 times and only 2 times with all 6 arguments than it is much more handy to write func(a, b) instead of func(a, b, 0,0,0,0). It i...

Thanks Filip,

Your workaround will not work i.e.
add(1,2,3) will return 3 instead of 6.
I'll try another approach.

Thanks again.

Hello,

Is i possible (and how) to use optional arguments in functions in mikroc?

Something like this: and use it as: ?

I couldn't find it. Thanks a lot!

Showing the code would help diagnosing your problem...
What does "DONT GET WORKING" mean? Can you be more specific(like: nothing on the screen, garbage on the screen....)?

If you want ppl to help you - you have to help us to understand your problem.

Dear All, Does someone have experience with interfacing the LCD16x2 with PIC via I2C port expander? I have the PCF8574 I2C expander and I assume it shouldn't be difficult to physically interface it, however I'm too newbe to even thing of writing my own library to access the LCD. If someone has exper...

Where is your LED connected? Should be to RA0 if it has to work with your code.
If you want to modify only one pin use PORTA.F0 = 1 or 0; where Fx is PORT pin number

I think I know what you want to say. If i'm not mistaken in your example when something appears on the RX the interrupt read single char, thats it. so when next char appears the interrupt will read the next char. In between something in the main loop is executed. Am I correct? The trick is as you sa...

@drdoug I used your example http://www.mikroe.com/forum/viewtopic.php?t=19530, although I'm not sure if my approach is good. Here is my code void interrupt(){ if(PIR1.RCIF) { // test the interrupt for uart rx GGA = 0; do{ if (Usart_Data_Ready()) { rxchar = Usart_Read(); if (rxchar=='$') {count=0;} h...

If I place the LCD_OUT outside 'if string GPGGA or GPRMC detection' but still within the do {...}while then I'm not detecting anything. The best would be to move inside of do...while into the separate function and then call it when data arrives (how?) and exit the function after receiving both strin...

Hi all, I have the small program to read GPS NMEA strings via USART and display the time from two strings: GPGGA and GPRMC. Example of those strings: $GPGGA,hhmmss.ss,llll.ll,a,yyyyy.yy,a,x,xx,x.x,x.x,M,x.x,M,x.x,xxxx*hh $GPRMC,081836,A,3751.65,S,14507.36,E,000.0,360.0,130998,011.3,E*62 The problem ...

@THE_RB I do have already the conversion routine. I was more interested in the routine which drives the FET for strong pull-up. Why you use only 120us delay after issuing CONVERT_T ? The conversion time is at least 200ms! meaning that you in fact displaying the temperature fron the PREVIOUS measurem...

It has 3.7 battery inside with the charging unit feed from my 5v line.

It is working now :D I'm still using usb cable (1,5m) and 20MHz xtal. I made simple (2 bipolar transistors plus couple of resistors) voltage level shifter - it was easier then using mosfet approach for which I would require use of 3.3V regulator. It goes Hi when input is above 2.5V Thanks a lot for ...
