I had used WIZ7010B in past and now trying with WIZ812MJ and having some problems
- What is the LEDs status if I just connect the Power pins of the module (Will both be ON ?)
2)What is the maximum (or minimum) data rate for SPI communication to these modules ?
I am trying to write/ and read back few registers to ensure that I have setup proper communication to the module, but I am getting some strange response. (All Registers appears to be 0xFF)
So I wrote a loop to read 0x15 registers in a sequence (from 0x0000 to 0x0015) the result I got was register 0x0000 was 0x00 and rest of them were 0xFF.
I changed the direction of reading ( from 0x0015 to 0x0000) so now result is changed 0x0015 is giving me 0x00 and rest of them are giving me 0xFF.
Is there any other way I can be sure that my communication to the module is OK ?
I am using Silicon Labs C8051F340 to communicate with the module. I had tried with 3000 bit rate to 10000 bit rate but same result.
Can you suggest anything ?
I had connected only 10 pins of the module and rest of them are floating. ( I am currently testing it on my proto board and will pull up/down the remaining pins in my final design)
These 10 pins are
2 ) MISO
I am not connecting any ethernet cable to it right now, and still my module is getting slight warm
