Describe the bug

I have a new board SAMD21 M0 size as Arduino UNO, compatible with Arduino M0, native port, with ethernet shield Wiznet W5100.
I tried example code Hello World, edit all serial.print to serialUSB.print and load to cpu over Native USB port, I have selected Arduino M0 board in Arduino IDE. Then, I get this from serial monitor:

I have a company network on 192.168.0.x with DHCP. Before, this shield I used with MEGA and webduino, working.
Thank you.

This means the W5100 board is not connected correctly and is not initialized.

Show how you connected (M0 pin <-> W5100)

Try the simplest WebClient example from Ethernet library and be sure working before moving to more complex libraries and examples.

I'm closing the issue now, and won't reopen until you prove this is a bug of this library.

proasnet · 2022-08-25T05:18:57Z

Thank you for reply. I tried this with SAMD21 M0 board and with Arduino UNO. Both with the same ethernet shield Wiznet W5100, Arduino original shield and WebClient example from Ethernet Library.
In this both cases, I only remove shield from the first to the second CPU board. In HW, nothing else.
For SAMD M0, I must edit all Serial. to SerialUSB. for usb serial monitor, nothing else.
I tried an external power supply for board, without any effect.
I'm starting to wonder if the Wiznet 5100 is compatible with the SAMD21 M0, but I don't have another ethernet shield at the moment

You have to modify these lines 73-80 from

EthernetWebServer/examples/HelloServer/defines.h

Lines 73 to 80 in 4fa2bca

    
           #if defined(ETHERNET_USE_SAMD) 
        
             // For SAMD

     #define BOARD_TYPE      "SAMD Zero" 
   #elif defined(ARDUINO_SAMD_MKR1000)

If not working, you have to connect directly from ICSP connector of W5100 to M0 pins according

W5100 ICSP	<--->	M0
MOSI	<--->	23
MISO	<--->	22
SCK	<--->	24
SS	<--->	16
VCC	<--->	5V
GND	<--->	GND

If not working, you can ask on Arduino Forum for help (M0 card bad SPI pins, M0 bad ICSP connection, etc)

Good Luck,

You can also try the new EthernetWebServer v2.2.1, which will try to auto-select the SS/CS pin according to board package

The third step, I can not found this pins 16-23 on the board.
Board has pins D0-D13, AREF, SDA, SCL, A0-A5 and ICSP, where is W5100 connected currently.
Thank you.

khoih-prog · 2022-08-26T05:12:10Z

Hi @proasnet

It seems that your SAMD21 M0 board's ICSP is not compatible with your W5100 SPI bus. I don't have that kind of weird board to test and help.

If you have the multimeter, you can check the M0 ICSP is connecting to which pins.

The remaining way is to read the docs, ask around the Arduino Forum, to match the SPI pins 23, 23, 24 and 16 to your SAMD21 M0 to D0-D13, AREF, SDA, SCL, A0-A5

Somewhere you can find the SPI pins used for that special M0 board.

khoih-prog · 2022-08-26T05:20:32Z

You can compare with the schematic at

https://robotdyn.com/pub/media/0G-00005517==SAMD21-M0/DOCS/Schematic==0G-00005517==SAMD21-M0.pdf

proasnet · 2022-08-26T05:43:37Z

Its the same
arduino-M0-schematic.pdf
I only found that this board HW-819 is compatible with Arduino M0. I not found schematic from producer of my board HW-819.
I wonder if the SAMD21 G18 CPU needs to define SPI with the help of SERCOM, but I have no experience with it yet and I can't do it. Yesterday I solved SERCOM for UART on my board, because I need 4xUART for my project and so far I'm just trying to set it up. I'm not an advanced programmer, you can say that I'm still a beginner.

khoih-prog · 2022-08-26T05:47:34Z

For M0,

Pin 10 <=> PA18

Pin 16 <=> PB09 <=> A2
Pin 22 <=> PA12 <=> MISO
Pin 23 <=> PB10 <=> MOSI
Pin 24 <=> PB11 <=> SCK

With your latest test, it seems that M0 is communicating OK with W5100 (no more no chip error).

Possibly M0 is bad (SPI, etc.) It's better you buy W5500 and connect directly to M0 to try.

I suggest you use RP2040 + W5100S or W5500, such as WIZNET_5500_EVB_PICO, WIZNET_5100S_EVB_PICO. More powerful and integrated.

Good news, I'll check why we have M0 problem getting correct IP address.
Possibly recent update in Ethernet_Generic v2.4.0 is not compatible with Arduino SAMD core ???

Releases v2.4.0

Using raw_address() as default instead of private IPAddress data

Add missing LibraryPatches for ESP32

Update Packages' Patches

If you're willing to spend some time to help test and fix the bug (as I currently don't have the same SAMD21 M0 board), I'll reopen this issue.

Steps to test

Install Ethernet_Generic v2.3.1 to replace Ethernet_Generic v2.4.0
Use the same example code of this latest EthernetWebServer v2.2.1

You forget to patch the core.

Anyway, add to defines.h

#define BOARD_NAME     "SAMD21 M0"

Great. You did it. Then change to use Ethernet_Generic library

proasnet · 2022-09-01T04:06:16Z

I updated previous comment, please see up. Thanks

Try comment out to see if better ???

// For other boards, to change if necessary 
  Ethernet.init (USE_THIS_SS_PIN);

It not help, the same result.

khoih-prog · 2022-09-01T04:24:32Z

OK, I think I found out the issue.

Try to add to defines.h before

#include "Ethernet_Generic.h"

such as

#define USE_W5100     true
...
#include "Ethernet_Generic.h"

and put back after OK to test

  // For other boards, to change if necessary 
  Ethernet.init (USE_THIS_SS_PIN);

The reason is old Arduino Zero can't use W5100-based shields faster than 8 MHz

Dear @khoih-prog ,
only as note, if this working with ethernet.h, is any reason for unuse it?
Only for my project, I am not need universal ethernet library.
Of course I'll help you debug the library.

Sorry, one more step ( to reduce clock to 8MHz from 14MHz) before we have to wait

The actual issue is that the W5100 is too old and it's better to use W5500.
The new Ethernet_Generic is the merge of several Ethernet libraries, such as Ethernet, EthernetLarge, Ethernet2 and Ethernet3 to deal with performance and support to many new Ethernet shleds, such as W5100S, Large buffer, faster clock, etc.

If you're using W5100, you can use Ethernet library, without problem.

proasnet · 2022-09-01T04:46:05Z

Thank you for the information. I bought my shield 3 months ago, there are a lot of them in e-shops. I also looked at the W5500, but I couldn't find one for a normal price as a shield, which is not on the wires, but as a plug-in module.

proasnet · 2022-09-01T04:47:42Z

I would also like to ask you if you would not modify the WebServer example with the ethernet.h library so that it is clean only for my SAMD21 M0 board, without the maze of else, else if endif, etc. It would take me a long time to clean it up .
Thank you very much

khoih-prog · 2022-09-01T04:48:44Z

One more change, if you have time to help

Comment out

https://github.com/khoih-prog/Ethernet_Generic/blob/main/src/utility/w5100.h#L110

//#define SPI_ETHERNET_SETTINGS SPISettings(30000000, MSBFIRST, SPI_MODE3)

Good news. That's really because of the too old W5100 requires slow clock.

I have another W5100 but never have this kind of slow-clock issue.

I'll make some notes and user configurable settings for W5100 in the new release.

proasnet · 2022-09-01T05:00:54Z

Good. Thank you.
Please, when you have time, please make me an example for my board and W5100 as a webserver with basicAuth.

PS: Bad luck that I just received the M0 board and it broken at the first try. So great quality. Have to order 2 more to keep for testing in the future.

I'm sure missing some lines somewhere. Still OK with Ethernet_Generic's WebClient_SAMD21_M0 ?

You have to wait some time until I receive the new boards ;={{

Okay, I am waiting :)
Thank you

hi @khoih-prog,
this example working.
Thank you.
Where was a problem?

khoih-prog · 2022-09-27T06:51:59Z

Missing

// Default to use W5100. Must change to false for W5500, W5100S, for faster SPI clock
// Must use true for SAMD21, such as Zero, SAMD_FEATHER_M0_EXPRESS, etc.
#define USE_W5100                           true

That's why the library tried to use the more aggressive SPI timings for newer boards, and SAMD Zero can't take it.

proasnet · 2022-09-27T07:27:57Z

Dear @khoih-prog , if this working fine, I trying find example with some form, for example as in old library, that I used in my project and I am reworking all for your library - setting ethernet parameters by web, setting other program values stored in flash.

After login to server, user or admin can display web form with traditional network settings, that is saved to eeprom in the mega case, with SAMD M0 to flash.
Can you recomed me some example with similar form, please? In your examples I can not find some POST forms.
Thanks.

khoih-prog · 2022-09-27T14:52:21Z

HI @proasnet

You can check the POST-related examples in this library, such as

If you need help, I suggest that you do some little Google-research, or post the issue on Arduino Forum, to ask for help from many experts there. I'm sorry I wish I have time helping and dealing with personal project.

Good Luck,
