gps chipset question
Hi all!
Do you know what is the best GPS chipset solution to embed in a tiny microcontroller application?
It's is hard to use?
Thanks in advance.
Re: Low Input Voltage
thanks for reply wizpic!
but i need a uC with a Vcc of 0.5-1.4, because i have a v source of about 1.4V and i don't want to use a boost to lose eficiency. It's to use in a portable application.
best regards
Low Input Voltage
Hi all!
I want to know if there are any uC that can work at 0.5<1V aprox. It is not important that it could be of 4bits.
thanks in advance.!!!
Linux embedded
Hi all!!
I want to buy a LOW COST pc embedded system to develop linux applications to test embedded source code.
Where i can find/buy a reliable system based, if it's possible in i386 processor?
Thanks in advance!!!!
Hi Flatulent!!!
Thanks for the schematic!!!!
My design is like yours, using npn & pnp bipolar transistor, but the switching induces a lot of noise of radiated emi, and it requires a load in the line.
I was thinking to implement it with power mosfets to reduce emi (or a ressonant circuit).... i...
Thanks a lot flatulent,,!!!!!!
But, how could be the schematic of the switching source?,
Actually at the end load, as you say , I put a TRT as a comparator to read the transmition...
a lot of Thanks!!!!
Thanks flatulent for you reply!!
I don't want/need a fsk modulation (this would complicate my design), actually, my design suports this low baud velocity (9600). I was thinking in a Mosfet conmutation with some second order circuit to attenuate the switching noise.
What do you thing about...
Hi everybody!
I want to switch between two DC sources (24V & 36V). These sources may supply a quite high current (0.5 A):
+------+
+24 Vdc o-|-o\ |
| \ |
| o-|-o Output (max. 0.5A)

+36 Vdc o-|-o |...
thx key,
I will try it.... my problem was with the compiler float library, it use almost 30 bytes of stack.
I choose HC08 to test the NITRON generation
Thanks
Floating point help
I need to implement floating point code in a 8-bit ,128 (RAM), and 1.5K flash memory microcontroller (Motorola).
I'm programming in C but the libraries are not optimized for a tiny microcontroller.
Somebody have any code implementing optimized floating libraries for a low...
