ENC28J60 Ethernet chip driver for MicroPython (RP2)

Last update: Nov 16, 2022

Overview

micropy-ENC28J60

ENC28J60 Ethernet chip driver for MicroPython v1.17 (RP2)

Rationale

ENC28J60 is a popular and cheap module for DIY projects. At the moment, however, there is no driver for the MicroPython environment. The Python implementation seems easy for further improvements and self adaptation.

Installation

Copy enc28j60.py to your board into /enc28j60 directory.

Wiring

Wiring requires pins for SPI: SCK, MISO, MOSI and ChipSelect and optionally Interrupt. Example wiring that uses SPI1 bus:

ENC28J60 Module	Rassperry Pi Pico	Notes
VCC	3V3	requires up to 180 mA
GND	GND
SCK	GP10	SPI1 SCK
SI	GP11	SPI1 MOSI/TX
SO	GP8	SPI1 MISO/RX
CS	GP13	SPI1 CSn
INT	GP15	Optional

Example code

Packet transmission

Example of packet transmission to broadcast ethernet address:

from machine import Pin, SPI
from enc28j60 import enc28j60

spi1 = SPI(1, baudrate=10000000, sck=Pin(10), mosi=Pin(11), miso=Pin(8))
eth = enc28j60.ENC28J60(spi1, Pin(13))
eth.init()

srcMac = eth.getMacAddr()
tgtMac = bytearray([0xFF,0xFF,0xFF,0xFF,0xFF,0xFF])
payLoad = bytearray(64)
pktType = bytearray([(len(payLoad) >> 8) & 0xFF, len(payLoad) & 0xFF])

eth.SendPacket([tgtMac, srcMac, pktType, payLoad])

Packet reception

Example of packet reception:

from machine import Pin, SPI
from enc28j60 import enc28j60

spi1 = SPI(1, baudrate=10000000, sck=Pin(10), mosi=Pin(11), miso=Pin(8))
eth = enc28j60.ENC28J60(spi1, Pin(13))
eth.init()

pkt = bytearray()

while eth.GetRxPacketCnt():
	eth.ReceivePacket(pkt)
	print('srcMac:', ":".join("{:02x}".format(c) for c in pkt[6:12]))

Using your lib with a pico

Hi I'm having a bit of trouble - I'm using a Pc running PacketSender in UDP mode, testing the Packet reception script on Pico

I think I should be seeing the rxBuf in the Thonny shell, I see this :-

MAC ADDR: 0e:5f:5f:20:58:28 ENC28J60 revision ID: 0x00

but thats all, on the PacketSending I'm sending out "thing" every second.

The only difference is that I'm using the instance of SPI with this detail

spi1 = SPI(0, baudrate=10000000, sck=Pin(6), mosi=Pin(7), miso=Pin(4)) eth = enc28j60.ENC28J60(spi1, Pin(5))

My enc is connected to those pins.

Does it have to be on SPI(1,........) ?

(the lib file is on the Pico in the /enc28j60 folder)

Question regarding the recieving and print of data

Hi Looking at and testing your 'Packet reception' script - when I run this code (altered the SPI pins to suit), all I see is the following -

I'm testing it by continuously sending out a data stream from PacketSender

I'm using Port 7 After your line rxBuf = .......

I simply added print(rxBuff)

Can you provide any hints ?

I was hoping to see the data

no stuff is not good what I'm sending at 100ms intervals - somewhere in the Rx packet
