hi,

i'm trying to do a pizeo buzzer on PWM_3, and I'm getting nothing. when moving to PWM_2 (and moving the wire from pin 20 to 19), it works fine.

is there anything special about PWM_3 that i need to be aware of? is it possible I have a dead pin?

i'm certain my trivial circuit is correct, as it works on my Netduino 1, and works on PWM_2.

thanks.

Hi.

I have a Netduino mini, and everything was working fine. I decided to update to 4.2

I followed the instructions here:

http://forums.netdui...-v420-update-1/

Everything was fine until I erased it. I applied 5V to erase pad, turned it off, then turned it back on (5V regulated to pin 21). 

I have an FTDI Basic breakout board at 5V:

CTS => GND

GND => GND

RX => Pin1

TX => Pin2

SAM-BA tells me "Connection Fatal /  Communication Error".

I've switched the TX/RX wires (pins 1 and 2), supplied 9V to pin24 instead of 5V to pin21. still no luck. i measure 5V on pin 21 when supplying 9V to 24. I've tried pin 23 and 4 for the ground wire of the FTDI. I measure 5V on the FTDI also.

I can see the Tx LED flash on the FTDI when SAM-BA is trying to connect. About 1 Hz. Then it times out.

I've tried using SAM-BA v2.8.

I've tried different jumper wires and a different breadboard. But I get no response from the mini.

I've tried erasing again with 5V multiple times.

Anyone have any ideas? By trade, I'm a .NET developer and like the idea of sicking with that language, and would rather not go back to arduino if i can avoid it. but for $30, i have not even gotten a blinking LED sample running on this mini. 

Thanks.
