Problem with Spi Bus

#1

Hello. I need to connect a W5500 at Wireless Stick Lite V3. Could you help me with information about de pin layout and software library. Thanks very much.

#2

I have the same problem.
Does anyone have any ideas to offer?

#3

What is the problem at hand? Do you have problems with interfacing, i.e. selecting the right SPI pins? Or are you searching for any library?

Thanks for your reply.
I have both problems:
I saw that there are several libraries of the “AsyncDNSServer” family, I tried a couple of them but I couldn’t get them to work.
I tried both with the Wireless Stick Lite V3 and with WifiLora32 V3, but without success.

I Tried whit this Pins (but I’m not sure if they are correct…)

SPI_HOST: 2
MOSI: 27
MISO: 19
SCK: 5
CS: 15
INT: 4

SPI Clock (MHz): 25

Thanks again for the help

Dear. I found one solution at this problem…
You need modify pin assignment in file "pins_arduino.h " (C:\Users\mtiba\AppData\Local\Arduino15\packages\Heltec-esp32\hardware\esp32\0.0.7\variants\wireless_stick_lite) .
For example:
static const uint8_t SS = 18;
static const uint8_t MOSI = 27;
static const uint8_t MISO = 19;
static const uint8_t SCK = 5;
Then I used #include <EthernetENC.h> for ENC28J60.
and SPI.begin();
Work good with different pin assignment.

Thanks for your help.
By doing some tests I succeeded, and it was simpler than expected: just put the correct pin sequence in the WebClient.ino (for example) file:

So, In the case of the Wireless stick lite V3 and W5500, I made the following changes in the WebClient.ino file, and nothing else:

// Optional values to override default settings
// Don’t change unless you know what you’re doing

#define ETH_SPI_HOST SPI3_HOST
//#define SPI_CLOCK_MHZ 25
// Must connect INT to GPIOxx or not working
#define INT_GPIO 48
#define MISO_GPIO 18
#define MOSI_GPIO 39
#define SCK_GPIO 38
#define CS_GPIO 20

Bye,
Marco
