MikroC's SPI Ethernet ENC28J60 Library

[ΔЅịMø]

Ready na. Kasi hindi naman 5V powered mcu nun.

Anong PIC model po yun sir? (wala kasing alam about PIC)

[dummy_c]

Plug and Play na yon prof.
As expained here:

may mga non-LF series PIC mcu that works fine even with 3.3V supply. i tried it with PIC18F2550, PIC18F2620. plus ung binanggit ni master Lurker na cheap PIC18F4620. these three are guaranteed working with 3.3V supply.

By the way sabay na tayo mag experiment sa ENC dahil hiniram yung module pati board ko.

On topic.
Heto yung pag configure sa iba pang pins sa PIC16f887 para sa simple examample natin sa taas.

Code: [Select]

       ANSEL = 0x0C ;          // AN2 and AN3 convertors will be used
        C1ON_bit = 0;           // Disable comparators
        C2ON_bit = 0;
        PORTA = 0 ;
        TRISA = 0xff ;          // set PORTA as input for ADC
I remove the button switches and output functions para madali lang natin ma discuss.
And madali lang din yan ma port sa ibang mcu.

@prof.
PIC18F2620. May udp bootloader na. Kaya no need for progrmmer na to upgrade firmware.

[ΔЅịMø]

Tanong po master _Lurker_. Bakit po kailangan nating gamitin ang ANA as well as ADC? Or baka i-didiscuss nyo pa po yung mga explanations ng code na yan.

OT muna sir _Lurker_:

Sir PIC, newbee question po. Ano po ang gamit ng UDP bootloader? Have googled it ang gives me this results:

Yung basic example ng mirkroC gumagamit ng ADC, button at output.
Yung button at output gumagamit ng script at looping sa HTML code niya,

Code: [Select]

<script>
var str,i;
str="";
for(i=0;i<8;i  )
{str ="<tr><td bgcolor=pink>BUTTON #" i "</td>";
if(PORTB&(1<<i)){str ="<td bgcolor=red>ON";}
else {str ="<td bgcolor=#cccccc>OFF";}
str ="</td></tr>";}
document.write(str) ;
</script>

Code: [Select]

<tr><th colspan=3>PORTD</th></tr>
<script>
var str,i;
str="";
for(i=0;i<8;i  )
{str ="<tr><td bgcolor=yellow>LED #" i "</td>";
if(PORTD&(1<<i)){str ="<td bgcolor=red>ON";}
else {str ="<td bgcolor=#cccccc>OFF";}
str ="</td><td><a href=/t" i ">Toggle</a></td></tr>";}
document.write(str) ;
</script>
Next time lang natin i-discuss yan.
Step by step lang master prof mahina ang kalaban.
Yung ADC lang muna ang i-discuss natin kasi marami din ito application like temperature and voltage telemetry.

[PlCUSER]

Ot:
Prof relate natin sa alam mong gamitin, si arduino. Si arduino ay atmega chip na may serial bootloader. Kaya you can upgrade the fw using serial comm (usb to serial sa case ni arduino).

Ung udp bootloader naman, you can upgrade the firmware of your pic mcu with enc module using ethernet port ng pc mo. Or even tru a wifi router.

Tama na daldalan prof. Makinig na ta kay master lurker. Baka batuhin na tayo ng eraser.

Yun pala. Kaya pwede ka makapag-"BURN" ng FW using USB post ng PC ko because of this serial bootloader na andun sa loob ng ARDUINO. Tama po ba sir PICUSER? Therefore, pwede kong i-"BURN" ang program ng PIC using Ethernet port ng PC.

Nyahahaha. Pasensya sir. Masyadong excited eh.

[RiDdLeR???]

Setup ko na yung breadboard ko.  Meron ako dito ideal PICs to use, PIC18F46K22, PIC18LF4680 at PIC18LF2685.  Subukan na nanatin.  Balik mikroC na naman.

[dummy_c]

Wow!
Amazing devices master alyas.



On topic,

Code: [Select]

unsigned char SPI_Ethernet_doPacket();
Process incoming Ethernet packets.
It processes next received packet if such exists. Packets are processed in the following manner:

• ARP & ICMP requests are replied automatically.
• upon TCP request the SPI_Ethernet_UserTCP function is called for further processing.
• upon UDP request the SPI_Ethernet_UserUDP function is called for further processing.

Spi_Ethernet_doPacket() must be called as often as possible.
Otherwise packets could be lost.

Code: [Select]

unsigned int SPI_Ethernet_UserTCP(unsigned char *remoteHost, unsigned int remotePort,
unsigned int localPort, unsigned int reqLength, TEthPktFlags *flags);

This is TCP module routine. It is internally called by the library. The user accesses to the TCP/HTTP request by using some of the SPI_Ethernet_get routines. The user puts data in the transmit buffer by using some of the SPI_Ethernet_put routines. The function must return the length in bytes of the TCP/HTTP reply, or 0 if there is nothing to transmit. If there is no need to reply to the TCP/HTTP requests, just define this function with return(0) as a single statement.

Parameters:

• remoteHost: client's IP address.
• remotePort: client's TCP port.
• localPort: port to which the request is sent.
• reqLength: TCP/HTTP request data field length.

Copy paste lang muna.

Ready na. Kasi hindi naman 5V powered mcu nun.

promise sir? promise ka muna!

[ΔЅịMø]

Pwede kayang i-simulate yan sya sa Prot*us sir lurker?

[Kaizer03]

^

yes...

BTW, ENC28J60 is 5V tolerant =)


--

nakakamiss ito,nakita ko na yung two boards ko for this, hope na magalaw ko ulet sya using my new workbench table

[dummy_c]

Share naman po sa nagawa mong mga projects master kaizer...

Prof iba talaga pag meron hardware.

[ΔЅịMø]

OT:

Kaya nga eh. Mata-try mo talaga sir. Di bali po sir, comming na po yung HW ko.

[dummy_c]

Excited na din ako sa new ENC at sa isa pang toy.

On topic.
Just a recap.
I have already posted the mikroC's simple hardware setup of ENC and PIC.
I also posted about how to configure the MAC and IP settings
as well as how to initialize the PIC mcu for it's CS and RESET pins.

So I think pwedi na tayo magsimula mag discuss a little about sa HTML.
Take note wala ako alam sa HTML so pleaaaaaaaaaaaaase bear with me. 

But first just a review.
We need to call "SPI_Ethernet_doPacket()" as much as possible to avoid packet loss.
Everytime we call "SPI_Ethernet_doPacket()" and an HTTP request exist (usually galing sa browser mo), it will call "SPI_Ethernet_UserTCP" to further process the request.

So based sa conditional statements na nasa loob ng "SPI_Ethernet_UserTCP" nag depend ang webpage na ilalabas ni browser.

Sana malinaw lang yan.

[PlCUSER]

excited na din akong matuto nito sayo master lurker. sa wakas....

Kuhang kuha sir.

[carlsberg11]

marami na akong babasahin nito sir lurker.. whew!! sige go lang ng go!!
