#55149 ICSP confusion can only see MiniJTAG. Please help

Posted by jacobgladish on 03 January 2014 - 12:53 AM in Netduino 2 (and Netduino 1)

Chris,

I haven't done extensive testing, but that seems to work. I can scan and connect to wifi and establish connections. Thanks.

 Cpu.Pin interruptPin = (Cpu.Pin)SecretLabs.NETMF.Hardware.Netduino.Pins.GPIO_PIN_D3; Cpu.Pin chipSelectPin = (Cpu.Pin)SecretLabs.NETMF.Hardware.Netduino.Pins.GPIO_PIN_D10; Cpu.Pin enablePin = (Cpu.Pin)SecretLabs.NETMF.Hardware.Netduino.Pins.GPIO_PIN_D5; using (var wifi = new WifiAdapter("Adafruit CC3000 Shield",     SPI.SPI_module.SPI1, interruptPin, chipSelectPin, enablePin)) {   }

[color=rgb(82,82,82);font-family:'Helvetica Neue';]On the CC3000 shield, we use the following pin connections[/color]

SCK - #13
MISO #12
MOSI #11
CS for CC3000 #10
VBAT_EN #5
CS for SD Card #4
IRQ #3

In WifiAdapter.cs I noticed these comments:

// On NetduinoPlus2:

// D4 is 28

// D5 is 24

// D6 is 25

[color=rgb(82,82,82);font-family:'Helvetica Neue';]Can you tell me how you get those pin numbers? [/color]

I have board stacked on netduino 2. I do not have the 2x3 ICSP header installed as it doesn't match the 2x5 on the netduino 2. There's also a schematic here:

Chris,

This is the closest I can find to any detailed wiring.

[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]<quote>var zeros = new byte[3 * ((32 + 63) / 64)];</quote>[/color]

evaluate what's in parenthesis first and use integer math.

32 + 63 = 95

95 / 64 = 1

1 * 3 = 3

[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]var zeros = new byte[3];[/color]

[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]why all the extra math? That's usually done to communicate that it's not an arbitrary number that the programmer has selected, but some function of other stuff. I have no idea why +63. [/color]

As fars as the zeros not being set, the c# compiler always initializes everything to zero. Numerics are 0 or 0.0, bools are false, and references are null. It's the same as this

byte[] zeros = new byte[] { 0, 0, 0 };

I think I have a very similar problem. I'm trying to get the cc3000 shield to work with netduino 2.

http://www.adafruit.com/products/1491

I assumed that I wouldn't need to deal with the ICSP pins on the wifi shield since I have the board stacked. Am I missing something?
