Then it is worth buying the amlpified modules. They say it goes up to 1Km. It should be a couple of hundred meters anyways. What do you think? http://www.ebay.com/itm/310651702557?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
So could you help me out with the patching? BTW when we can expect the next ernergia release?
The MCU is MSP430G2xx3 and the display is Nokia 5110. The project is not finalized, I will add schematic and board later on.
Here are the specs:
Number of channels: 2
Reference: internal or external (space for optional Maxim's, Linear's, and TI's Vrefs.)
Optional shunt resistor.
Host connection: SPI, UART (optional RS232.)
Optional resistor divider and multi turn pot.
Two general use outputs/inputs
Board size: 45mm x 45mm (50mm with optional switches and LEDs,) matches 5110 footprint.
Little background. My original panel meter was designed to fit behind 4 digit 0.56" LED display. Then I figured it will be better to use 16x2 LCD which will let me display more information. Now, after playing around with 5110, I decided that this display is the perfect choice for me since nothing beats nice GUI.
