@ahmedadelhosni : no luck! Here same for us in France. I think it's because they handle our package from airport to house...but have we not already paid for this! There is vat of course too, but here vat+15euro extra mystical handle fee.
Fun, is when you want to make a joke to the dhl person and you ask why fees, I don't want pay, give me my package, no come back!! ahaha they are not funny :) At less, if they were doing right their job, 4times/10 they say "you were not here"??? yep, but I was there..and where is the paper in my mailbox, nothing...arrgh! what do you think I will wait you on the road???

No matter, looking at your package, I think you will have lot of fun :)

@scalz Seeing that someone else had the same issue made me better hahaha :)
The problem that I went myself to take it today and they told me that I have to buy for the customs and the government.

I need to calm down and have fun better. Thanks :)

@betonishard A few "unused" bits of the Ext fuses are differently written in avrdude (Arduino IDE) and Atmel IDE programmer implemetation. That's why the same settings can look different. You have to know which one you use.
Search for "Avr fuse calculator" on the internet and some will show you fuses for both methods.

I also had issues with avrdude when I started and never got it to work. A lot of others do of course, but I found the Atmel way easier for me. Hence only this is shown in the pictures. The bootloading business is not easy and a lot of info is availible on the arduino forums. I think the only way is to read and study.

Hello all,

I have been struggling with this for a couple of weeks now and I just can seem to figure out a good way to upload sketches to the arduio328p-pu. First of all I use this setup;

I use arduino for mac 1.6.5
I use a breadboard with a crystal, two capacitors and a resistor between reset and 5v.
An arduino to burn bootloader (with the chip inserted and sketch arduinoISP uploaded).
I use the same hex files as you guys with 1a. I used the optiboot 9600 BOD, just the 9600 and the 4800. Uploading the bootloader is no problem at all. Arduino ide burns the bootloader without any problems. However when I try to upload the sketches I get different errors. The “Yikes” version in which it states that my device signature is not ok and programmer not responding. I use upload using programmer.

So, I tried to upload the arduino uno version to rule out all miscabling. So what I did was upload the arduino uno bootloader, tried to upload the blink sketch afterwards and it works. So my cables are ok….

I thought to repeat the exact same process with the boot version above. However no succes, I keep getting stuck at uploading sketches. Is it just not possible?

I read about setting the fuse options and I read that when you define these in the boards.txt, they will be set as the fuseparameters. When I check the boards txt above i see that fuse settings are: L0x62,H0xde,E0x07, however when I open the png file (first post, fuse settings) it states L0x62,H0xDE,E0xFF. Furthermore the lockbits are at 0xCF, compared to the boards.txt 0x2F. What is true and how should I set these. I don’t see a possibility in arduino ide (I use another arduino to upload, so I don’t have a tiny or USBASP.

Help would be much appreciated here because I have like 30 boards sitting catching dust.

Hi, i had the same problem, but then i tried the 1b hex and since i burned this it works for me.

Makes sense to me. By closing the contact you get a path from 3V3 via the pullup resistor to ground.

The current is (for a pullup resistor value around 30KOhm) arounda lot of 100uA.

Try NOT using the internal pullup resistor of pin D3, and using an external pullup resistor of 1MOhm or more.

You will see lower current when the contact is closed.

Yesterday i get a lot of resistors, now i testen 1Mohm and the current draw is around 4 µa, but now the arduino do not recognize when the reedcontact is closed or open. When the contact is closed the current draw is 4 µa when opened 1.2µa
do i have to edit the sketch in order to get it to work?

GertSanders

@meddie
The pull up 1MOhm resistor should go from Vcc - resistor - D2
The switch should be connected to D2 and Gnd
D2 needs to be defined as INPUT, no need to add the statement with PULLUP.
Post your sketch so we can have a look.

digitalWrite(PRIMARY_BUTTON_PIN, HIGH);

If you use the external pull up, you need to comment out these two lines like so:

// Activate internal pull-ups
// digitalWrite(PRIMARY_BUTTON_PIN, HIGH);
// digitalWrite(SECONDARY_BUTTON_PIN, HIGH);

No need for an internal pullup if you use an external pull up.
In the above I'm assuming you have an external pullup resistor for each digital pin, one for D2 and one for D3.

@ahmedadelhosni You know that the nRF pins are not centered? That means if you rotate it like this it will no longer be straight above the "slim node motherboard".
What height do you expect it to be?

I understood now what you meant by "not centered". Thanks for notifying me.
I'll take care of that.

betonishard

@meddie are you also using the optiboot 9600 NOBOD in boards.txt the same as in the first post (fuse settings I mean)? And are you using avrdude arduino ide for mac?

I tried your solution but i get the same results.. Yikes!

If you use the same setup, can you post your boards.txt? Did you also make changes to the hex file?

Thanks in advance.

betonishard

@m26872 Thanks for your answer... The problem is I read a lot about it (which makes me kinda stupid that I still haven't achieved this).

I tried to find atmel studio (I believe you are referring to atmel studio?) I couldn't find a proper mac version. I checked on the fuse calculator and still no success. Maybe some one could give me the correct fuse settings for AVR or a proper mac download link for atmel studio.

OI know I am asking a lot, but it would help me a lot. Thanks.!!

m26872

@betonishard Yes, of course ask if you have problem. But I suggest you also make a new separate thread in General-, Hw- or Troubleshooting section about your issues.
Maybe it's a good idea to ask in arduino forum as well.

ahmedadelhosni

Hello @m26872

I succeeded now to burn the bootloader which you used (1Mhz). I just don't understand a phrase which you mentioned above.

According to this you should use minimal startup time to reduce power in every 8s sleep cycle, but for the moment I don't care and stick to the default 65ms.

Can you explain what is this ? and whether it is affecting badly on something or not ?

Thanks..

meddie

its the fuse, which defines the rising time. the oscillator needs some time to come to the correct frequency. If you dont wait this time its possble that your sketch dont work correctly. But the microcontroller is the 65 ms longer not in sleep mode and need more battery power. but works more stable.

meddie

YEAH, YEAH YEAH! Thank you all for the help a big thanks to GertSanders. Now it seems to work perfectly. The current draw is now 4.6µa. Now i have to transfer from bredboard to pcb.
Thank you very much!!!!!!

@ahmedadelhosni I've never verified it by measuring, but I understood like @meddie about Gammons writing.
To get rid of those 65ms startup time you should use fuses 42-DE-FF (Lo-Hi-Ext) instead of 62-DE-FF.

If anyone could verify and measure current between sleep cycles and share some results, it would be great.

betonishard

@meddie and @all Tonight I think I have fixed my issue however how I do not understand so maybe someone can explain, or maybe I think I have fixed it and it is not fixed at all.

On the arudino website it states that when you burn your bootloader you have to connect pin 13,12,11 and pin 10 to reset (and ofcourse 5v and ground). AFter burning the bootloader you should replace it with the rx and tx cable and disconnect 13,12,11 and connect reset to reset. Each time I did this I got the error of Yikes! However tonight by accident I forgot to rewire the pins to rx and tx and press “Upload using programmer” all of a sudden it stated “done uploading”.

I tested this with blink sketch so I attached a led to pin13 and ground. The led started to blink. I was happy however did not understand…. or is this just a n00b mistake

Hi, i had the same problem, but then i tried the 1b hex and since i burned this it works for me.

@meddie @betonishard I guess I know the solution. Yesterday I begun creating my nodes with the same setup and faced the same issue. When You upload your sketch, choose your board, and the important thing which will solve the "Yikes" error, is to choose "Arduino as ISP" not "ArduioISP". You will find it under Tools > Programmer.

Another thing. If you are chip is the one which comes with the arduino UNO, then you have to add a crystal at the first time when you change the bootloader. According to what I read yesterday (and this solved an issue also which I faced) that the chip is already configured to use external crytsal. Thus (for the first time only), I tried adding a 20 Mhz, and 10Mhz as I didn't have 16Mhz, and surprisingly both configurations worked :)

let me know please if that helps.

ahmedadelhosni

@meddie THanks for the answer.

Can you please also explain your final result to reach 4uA. I have also the same problem and current is 90uA and sometimes drops to 20uA, then rises again. Thanks.

Edit: I figured out that I was using the 3.3v from arduino UNO. CHanged to two 1.5 batteries. THe current drops to 1.4uA when contact is open but sometimes it is also 15 uA. And when contact is closed it is 60 uA, and sometimes drops. Don't know why it is not stable.

Edit 26.1.2016: I managed to reach 1.4uA with door opened, and 15uA when closed. I guess the problem was with the wiring. DOn't really know but I used a battery holder instead. I will try to rechange the resistor value to 1Mohm and reupdate.

Edit 27.1.2016: ok I created another node and connected the contact sensor in series with the 1Mohm and the output is the voltage divider. now it is 1.4uA when open and 4.6uA when closed.

Thanks
