Hi all and Thank You,
I have good enough (not perfect) suppression of EMI induced by GSM with ...
bigger capacitors in power supply(And capacitors are main difference between two boards).For those, who is interesting - on board is linear regulator LM2954IM.Output capacitor was 100microF, for...
Hi Melone,
Metal box is not good for me.
Wires between PCB and load cell are:
to loadcell -> +5V and GND
from loadcell - 2 wires differential signal
shield (grounded only on PCB GND)
When i make short circuit between differential wires - on PCB side, there is no interference (may be )...
Hi,
I am experimenting with weigh scale - load cell + analog/digital microcontroller MSC1210 (Texas) . When i put my GSM close to cable (from load cell to converter), scale display is changed significantly.
GSM is active - calling to other phone.
With other type ADC (Texas ADS1240) i have not...
If Your printer/plotter is passed to '*.plt' file
then you can "copy xxx.plt lpt1:" - ".plt" must be produced
for Your hardware.If it is not:
if '.plt' file is hp-gl (hewlettpaccard plotter language)
you can import into coreldraw, other drawing programs, or even msword...
plot from acad to hpgl (7475,7580) and search for
converter hpgl->gerber . This is easy way, but -
maybe acad will draw with very thiny pen and file will be too long -> on non-laser gerber ploter this will be too slow and maybe - not good enough.
AD7730 AVDD can be turned on after DVDD. In my design AVDD (5V) is turned-off in power-minimizing mode and turned-on again, when key is pressed(VDD=3.6V). All IO wires are trough 470 Ohms passed. In my oldest design no resistors are used (but AVDD is tied to DVDD=5V). In oldest design
i have one...
