Thanks baxter, I'll be sure to make a post when the driver's ready so that I got something to show you.

your radio or host board? I've flicked pwr_en high and low just fine, so maybe double check the wiring, maybe it's OK!
The radio, when trying to set the pwr_en input pin high by applying 3.3V to it, it seems to result in a short circuit.

Hi guys, I'm back from my holiday now and was looking forward to work on the PCB that I set out to do in Eagle, but...
While I was gone, my commercial IO board launched so I need to attend to that in improving the software, writing docs, creating sample projects and so on. This means I won't have time to work on the PCB for a good while.
I'll be happy to see someone else pick it up instead and since I didn't get farther than removing the mosfets, there's little point in me posting the Eagle files.

It's based on the RAK410 module, specs are here:

To the left is a PeekyPokey used to explore the API since it's more conveniant to do directly from the PC. When I'm done, I'll move the code to the Netduino.

Great, those are some really good guide lines!
Admittedly, I haven't read your posts all that thoroughly yet (it's late over here) and surely there are things to be discussed but just to be clear that I was merely picturing a really basic (yet powerful and versatile) Wifi board for the common Netduino user to benefit from, not the next "Wifi Ûbershield" :-)
Primarily, I was thinking a Netduino specific board with header layout to match. Heck, the world is overwhelmed by Arduino stuff as it is, and it's not like we would be making a zillion unit thing with a technical height that could withstand more than a week on eBay given every little peace of additional hardware adds to overall costs in terms of time and consequently that of gold.
Basically making a few simple mods to that github board (undoubtedly nice work) in order to get a cheap, quick and dirty wifi board for the whole Netduino family of boards (not excluding the mini) with a managed driver to go as I know of which the ancient lady warrior being extremely resourceful when it comes to the latter of things :-)
@ziggurat29: Have you ever considered politics or have they perhaps already got to you?

SCI_VOL is a h/w register of the vs1053b chip, so you need to write the value 0x2424 to the register. You do this using the serial command interface (hence the "SCI" prefix) over SPI.
// Write to an SCI register
private void WriteRegister(byte address, ushort data, bool waitForDREQ = true)
{
wr_buff[0] = 2; // write command
wr_buff[1] = address; // register
wr_buff[2] = (byte)(data >> 8); // high byte
wr_buff[3] = (byte)(data & 0xff); // low byte
SelectCommand(); // select SCI
if (waitForDREQ) AwaitDREQ(); // wait for dreq to go high
spip.Write(wr_buff);
}
// example of setting volume
WriteRegister(REG_SCI_VOL, 0x2424);
The code snippet above is taken from my source code (puplished earlier).
I would use a rotary encoder but if you want to use a potentiometer, you can set it up as a simple voltage divider GND - 3.3V and then read the voltage of the wiper using a Netduino analogue pin. You would then need to add software to continuously poll the analogue pin for any changes in voltage, executing the corresponding volume adjustments.

The 16 bit register is divided into two bytes of 8 bits (256 steps) each, you need to set the two bytes separtely like so:
byte left_vol = 45; byte right_vol = 90; ushort vol = (left_vol << 8) + right_vol; WriteRegister(REG_SCI_VOL, vol);

Great, that you found it useful!
I saw your antique radio project and I really love the mix of new and old that you get from putting new internals in old machines.
My late mother used to have one similar to yours, you'd have to wait for like 15 minutes for it to get warm before you could use it. Sadly, we didn't keep it.
Cheers!

Great to see that something useful came out of this and I hope you were able to reuse some of the code from this thread.
Also, thanks for recognizing our work, to which I believe ziggurat29 contributed the most.

I'm sorry but I really think you should refrain from posting the entire listing in this thread, not just because it's really long but because it has very little to do with mIP.
Please modify your last post, remove the code and instead attach it as a file to the MCP23S17 thread. In that new post, please also point out any specific problems that you want me to look into.

When re-reading my last post I realized that I may have sounded grumpy and if so, I'm sorry because I didn't mean to.Sorry post to wrong thread.
You're doing a great job Andy and I'm glad you have taken interest in this. Please do make a new post in the MCP23S17 thread and I'll do my best to help you.

I'm sorry for not being of much help here but I've never dealt with that M2Mqtt.
Did you solve the problem eventually?

Great!
As for multi SPI, I could make an interface for the internal multi SPI mgr implementation of my MCP23S17 driver and expose that from outside the class.
You would then have to make some modificatins to your local mIP code to have it use the interface supplied by me rather than accessing the SPI module directly.
The latter would probably only be a little more than search and replace but still, you would break away from the main track of mIP. This is what I meant before when talking about the lack of a standard multi SPI mgr that can be shared between code originating between different contributors.
EDIT: Just discovered, mIP also includes a multi SPi mgr (borrowed from Stefan Thoolen's Toolbox)...

That sounds very familiar to me :-)
Andy, just skip internal pulldown (change the parameter) and put an external resistor instead of some 10k - 100k from the IRQ pin to ground. Could even be, there's already one fitted on your ENC28J60 board.
Also, double check to make sure the IRQ and CS pins are not swapped, parameter-wise that is.

I don't have the code at hand right now but the last two arguments of the Start method are likely the chip select and interrupt pins respectively.
The numbers are just the numerical representations of the corresponing pin constants/enums and so, in your case, you should be able to simply replace those with D10 and D8.

You need to connect the SPI pins (e.g. miso, mosi, clk, !cs), !int and of course vdd and gnd. I beleive the !reset pin to be optional.
I used this board from Sure Electronics:
Even though your board probably looks different, it should have those same pins.
Oh, about the profile, you can either change one of the existing ones or add your own, its only a matter of reflecting which Netduino pins you are actually using.

Check your SPI wiring and again that the CS and IRQ have not been swapped.
Could you post a link pointing to the ethernet board you are using and perhaps also a photo depicting your wiring?

You should be using the constants/enums corresponding to the pins on your Netduino instead of the numerical values from the original code.I guess that D8 does not equal (Cpu.Pin)8 in reference to a standard netduino 1?
Would this be 62 at a guess?
And D10 would be 64?
Many thanks
Andy

It seems name servers does not get configured correctly via DHCP with MIP even though there is one in your network.
Perhaps ns info somehow gets garbled after all - maybe you could debug the method that printed the ns info earlier and see if it is actually stored like that, e.g. if in fact MIP thinks that "192.168.1.1.192.168.1.254" is the configured ns - if so, there could be some problems with string handlng during DHCP processing.

Good job!
I guess it's sort of a bug but mostly because mIP hasn't been tested with all that many routers yet
If you haven't already, could you please report your findings on the mIP CodePlex site or perhaps send a personal message about it Valkyrie-MT briefly describing the problem, what you did to fix it and the name/model of your router?
So I take it, you got TCP/IP up and running now then - that's great!
