💬 Stamp size MySensor node
-
@GertSanders What is the difference between the v1 version of your stamp size mysensor node that's on OSH PARK and the V2 version that's on your website that you linked to in your OP ( https://www.openhardware.io/view/76/Stamp-size-MySensor-node )?
@NeverDie
None. The plan was to enhance it, so I copied my version 1 to version 2. But then I decided to publish it in Openhardware anyway.
This board is a proof of concept for me.
My next version will have a 8Mhz crystal. The addional powerconsumption is negligable bit the accuracy of timing is much better (and constant, even with dropping voltage).
So the board on OSH Park is identical to the one on Openhardware.io -
Thanks! I ordered it yesterday from OSH PARK, so good to hear.
Have you found something where you really do need the 8mhz crystal oscillator, or were you adding it as a "just in case"?
@NeverDie
I have a use case where I need the clock to be acurate. For realy low power nodes like the ones with reed switches, I also prefer the internal oscillator. -
Goedenavond Gert,
What's your boards.txt file is saying please? I uploaded the bootloader (optiboot_atmega328_08M_038400_D8) and all went OK until I upload my first sketch.
After that I am getting:avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x32 avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x0f avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0xfb avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x32 avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x0f avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x73 avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0xff avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x32 avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x0f avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xfbI have to upload the bootloader again in order to upload the sketch - something is clearly not working.

The standard file is just not good. I'll have to find the right one for tqfp chip.
EDIT: copied the "eightanaloginputs" variant in the variant folder, but still can only upload the first sketch after the bootloader, all other uploads are giving me "avrdude: stk500_getsync() attempt x of 10: not in sync:"

@GertSanders Gert, what pins_arduino.h are you using for this board please? Can you post it here?

@GertSanders Many thanks for your help. This is probably my bad luck, but I have mixed up C1 and R1 mounting them vertically (not horizontally). What a stupid mistake really given that I have checked it a few times. Anyway, now everything is working.
FYG, I looked at your pins_arduino.h - this is a standard one and it is not correct. I corrected the following entries:
static const uint8_t SS = 14; static const uint8_t MOSI = 15; static const uint8_t MISO = 16; static const uint8_t SCK = 17; static const uint8_t SDA = 27; static const uint8_t SCL = 28; #define LED_BUILTIN 8 static const uint8_t A0 = 23; static const uint8_t A1 = 24; static const uint8_t A2 = 25; static const uint8_t A3 = 26; static const uint8_t A4 = 27; static const uint8_t A5 = 28; static const uint8_t A6 = 19; static const uint8_t A7 = 22; -

OK, I will check also on my side :-) Thanks for the feedback. -

OK, I will check also on my side :-) Thanks for the feedback.@GertSanders No worries! And signing works flawlessly on this node as well with ATSHA204A by the way :)
-
@GertSanders You are welcome :) Btw, if you just patch in support to generate random data for a nonce, you can use the soft signing backend on rPi.
Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

@Anticimex
Well that sounds simple, but I'm more a hardware contributer, this is beyond my capabilities :-), especially in unix arena. I manage software developers for a living, so I know how much I do not know. -
Hello guys,
I am about to solder first PCB of this version. Just to be 100% sure, regarding C4 - what is the best value to use 1uF or 10uF, because I can see we can choose.

Thank you for the update,
Last part what I am missing is battery holder. I was trying to search it in many stores located in my country however I was not able to get it. Is there any internet shop when I can buy online? I have one workaround to soldier different CR battery holder and connect via wires.RPI2 + RFLink + PiFace D2 + Aeon Z-Wave Gen5 + Foscams FI9821P&R2 + MySensors + UPS APC Back-UPS 950VA
