YOU HAVE TO ENTER THE CORRECT SERIAL PORT AND RIGHT BAUDRATE IN PUTTY - THAN CLICK CONNECT

 

EDIT: MY KEYBOARD IS DAMAGED; CAPSLOCK IS STUCK - YOURS TOO??

it has, its called visual studio

iam against sections for different languages. but one for like codeshare would be usefull

 

another update!

 

its not blinking for the eyes!

instead of enabling dhcp setting an ip

read doesent return the actual voltage, it returns the voltage in percent, where 0.5 = 50% = 1.65v, 1.0f = 100% = 3.3v when you connect it it should read 1.0f (or something like 0.999f). when you multiply the read value with 3.3 you get the voltage. (microsoft class, id never used the sl one)

netmf is not realtime and quite slow (for what you wanna do), but you can add some native code in the firmware.

heres my little playground.
it contains:
netduino mini
102x64 lcd - spi
9dof imu sensor module + barometric sensor - i2c
128kb eeprom - i2c
temerature sensor - analog
trackball connected to pcf8574 - i2c
mcp23017 - i2c
4bit 7 segment (not connected atm)
sd-card slot - spi
real time clock (drifting a lot, like 2-3 secs an hour ...) - i2c
cp2102 usb-uart bridge
ftdi usb-uart bridge
max232
one step up and one step down module for 3.3 and 5v power supply

not on the sceen: joystick and led matrix module.

soon ill add a spi master <-> spi master wireless chip (NRF24L01+)
maybe some pIR chips (but well, they work without netduino/uC also)

next month plans:
i2c camera module (to save some pictures on the sd card) - not doable
bluetooth module - i hope i can get it to programm my netduino w/o cable (!) - working
ENC28J60 network module (spi) - dont have ethernet cable right now
TEA5767 fm radio (i2c) - todo

ill make better pictures as soon as i get my hands on a real digicam, not webcam as of now


everything now is working ofc
(except the imu, need more code for them, in progress!) - imu working (at least i can read the basic values)


greetings


// edit: some video of my compass in action.
atm it sends its data per uart to pc, gets rendered there in xna

its on my old led matrix




//edit: COBS and a simple UART transport system added
// cobs is just ported from original author // damn - link is gona and i dont have it anymore

//edit multi I2c and temerature sensor code added, its a smooth sensor, change history lenght to //make it faster

 

//edit: i now hooked up my rgb matrix

its only 3bit color, but still impressive

i also designed an app with that i can create images in color for it, its still in progress

(i klick the pixels, it shift to the next aviable color, a button to save it to a file is missing)

 

i also made a small "testbench" wich connect per uart to my netduino, and is capable of read/write register for a specified device (in that case my gyro sensor)

 

//edit: change in uart.cs its better now > it waits till it actually received the data it expects

uart class deleted for now, it has a memory leak

 

//edit: drivers for the mcp3201 added - 12 bit external adc.

also the uart bug seems to only affect stm32, have to look further into that.

 

// edit: uploaded a fixed version of realtimeclock (ds1307)

It is just a logical change (*), normally 0% = off and 100% = on, inverted 0% = on, 100% = off.

(*) The microcontroller allows configuration of PWM polarity, but it is not available in .NET MF classes.

sure its aviable and works!

PWM ladi = new PWM(PWMChannels.PWM_PIN_17, 1000, 0.5, true); // standard netmf pwm class
//edit: in 4.2

you should really get some basics first before you try to port code.
stuff like: you press a button, a led turn on, you press it again, it turns off
than go for analog-digital-converter, pwm, communication busses (spi, i2c, uart)

heres is a good tutorial to start with, it has more pages, you should read tham all

Good Start

i have made a simple sample too

forum link to it

you can just use analog, it can read digital signals too... digital is 0v and 3.3v //edit do not use more than 3.3v on analog pins //edit iam also not sure if you can connect gnd to analog. someone can confrim this?

hanging on the socket.Accept()

its a blocking function, it does not not hang, it waits there till a client actually connects

i made a short non blockinmg (threaded) sample for networking

yes its possible, but keep in mind one port is rs232 and one is uart, so it wount work with the same ftdi cables, you need different

//edit:
iam using an max232 to step up my ftdi chip for the com2 port for deployment, so i have the uart (com1) free for device to device/pc communication

//edit the code for that would be something like this:
sample 1
sample 2

i have no idea if this is possible, but if you store data more frequently i suggest using external flash or eeprom. 10 or 100 thousand cycles seem much, but when you write it frequently it wears out quick.
