A rather unelaborated question...
Then Why bother answering
How much time did you spend to find informations on your own?
14 years
Do you know that there are different bluetooth standards?
Yes
Did you check what BT standards your phone supports?
I’ll check tonight! So what....
Are you aware...
Hello,
I have been proposed to make an iPhone application that must connect wirelessly to a
a target board that has Bluetooth capabilities.
I know that the iPhone (IOS) communicates in either wifi or Bluetooth.
I am therefore wondering what Bluetooth chip is able to communicate with the...
Hello,
I am thinking of using the CC2500 wireless
chip from Texas Intruments.
https://m.ti.com/product/cc2500
The protocol on the chip is based on is called 2.4GHZ proprietary
protocol.
What is the difference between the 2.4 GHZ
Proprietary protocol when compared to
Other protocols like...
Hello,
Can someone explain to me what MC means when they refer to symbols on page 98 (Figure 3-4 -Super frame structure-) of the following spec sheet:

Hi Schmitt Trigger,
Ok well good points.... I guess will go with MKE RTC2 which has the same DS chip that you mentioned.
One thing though, although the DS1307 has real time and takes care of months, days and leap years, does it take into account the day light savings time.... For example days...
Hi Okada,
Thank you for offering your generous help.
So this is the way I see it. Using the internal RTCC of the pic is good but I will still need an external battery chip/hardware to do the transfer of battery power in the event of power loss.
So I may as well go with an external RTCx click...
Ok thank you very much for your help.... All valid points here! All I need is a simple way to track calendar time and the internal RTCC in the Pic32 seems to appeal to me. But on the other hand an external DD RTC chip would handle the battery switchover operations. Hummmm ! I'm undecided...
Seriously!!! That's the one I'm using....
Let me look into that....
Thanks Okada

Okada, are you familiar with Mikroelektronika?

Ok thanks Easyrider83.
Hello,
I am using a PIC32 uC and on board space is critical. I have created a timer Interupt routine which constantly increments an extern variable. The count this variable holds is the number of 4 ms time slices.
Therefore I am able to count the time slices and decern seconds, minutes, hours...
Hi FvM,
Ok this seems like an alternative. However I may change my design ... I need to think this through. I think I will go with a simple 7 segment display driver (with select pins) to drive one of these:

Let's see what I decide !
Thanks for your...
Hello,
Does anyone know where I can get the MM5484 part? I know that it's a Natinal part but don't know if I can buy from National. I also checked Mouser and they don't carry it ��
Does anyone know of a similar part that is more mainstream and sold at regular places like Mouser...
Ok guys,
Ooops sorry o don't know where I got 1khz??? ?
I will take post 8 and 9 into consideration and will try to make brad's circuit?
Thanks everyone for your collaboration and thanks Brad for your generous reply and contribution to this thread.
I will let you guys know how this pans out ☺️
Hi chuckney,
Thanks for replying ?
Ok so you are saying that brads circuit is a good circuit to go with and I thank brad for coming up with it ?.
But I have a question. Brads circuit doesn't even use an LM317.... It's just a transistor that drives a led ???
If this is so then why is...
Hello BradTheRad,
Thanks for replying and thanks for taking the time to answer my thread.
So in your resolution I see you are suggesting a 1 kHz signal to the base of a transistor driving the LED.
Well, that's not the signal I have. The only control signal I have is a 0-10VDc (@20ma max) dac...
