Re: DHT11/DHT22 humidity sensor reader advertisment

Thanks for the offer and explanation.

It was only curiosity on my part, so I will say thanks... but no thanks.

Cheers,

Ross

I still get all forbidden... I guess I am not trust worthy enough. :)

Re: Atmega16 5v self powered schematics

Hello.

If your processor is to be powered at 5 volts, you will need to reduce/limit the usb D+ and D- signals to 3.x volts which is usually done by inserting two 3.6volt zeners across those lines (with suitable resistors).

Does that answer your question?

Cheers,

Ross

Do you seriously believe that the original poster has been sitting around waiting more than 5 years for your reply?

Re: USB "helper" for V-USB prototyping

Here is mine. I have done several designs using V-USB. These have been done on the Mega8, Tiny2313, Tiny85 and Mega88 chips. To avoid the repeated exercise of doing a prototype for each processor I made a single pcb assembly that includes the USB connector for testing after code downloading, optiona...

Re: HIDKeys: issue key on both press and release

Hi Blarrg. Granddaughters have gone back to their parents and I have just tested your code... successfully. Thanks. Now I need to understand it and extend it so that multiple keys can be pressed and released without interfering with each other. Another day... another quest. Cheers, Ross (who has bee...

Re: HIDKeys: issue key on both press and release

Many, many thanks.

I will test it after my granddaughters (5 and 3) go home tomorrow. At the moment that are using 120% of our time and energies. :lol:

HIDKeys: issue key on both press and release

Hi everyone.

Has anyone succeeded in being able to issue a key on both a switch press and its release? I have tried a few ways but been unsuccessful. A clue to get me in the correct direction would be appreciated.

Thanks,

Ross

HIDKeys: usage of PD1

Hi all. The HIDKeys sample application provides for 17 keys. The pin assignments include "PD1 debug tx". The circuit diagram shows PD1 disconnected and yet a portion of the "hardwareInit" function states... DDRD = 0x07; /* 0000 0111 bin: all pins input except USB (-> USB reset) *...

Re: Is USB_CFG_MAX_BUS_POWER critical?

By setting the configuration variable to 100mA when your load only uses 50mA, you are not using or losing an extra 50mA. The variable does not force your "load" to use an extra 50mA. However, if you set the variable below what your circuit needs, the host (PC) will refuse to give you more ...
