Ok here is what im thinking and lets see if im WAY off base. I took apart a older USB Delorme GPS.
Inside was a STA2051E Chip Sta2051e PDF its the 144 pin type. Now on it has MOSI MISO And Sck pins. So once powered will it start streaming GPS data ? and if its that simple , can i just use a GPS library ? If its was USB , i would think that the Arduino UNO could handle it ?
Anyway Lets hear the Ideas
Two Serial Peripheral Interfaces (SPI) allow full
duplex, synchronous communications with
external devices, master or slave operation,
max baud rate: 8Mb/s. One SPI may be used as
Multimedia Card interface.
â– Two I2C Interfaces provide multi-master and
slave functions, support normal and fast I2C
mode (400KHz), 7/10 bit addressing modes.
One I2C Interface is multiplexed with one SPI,
so either 2xSPI+1xI2C or 1xSPI+2xI2C may be used at a time.
so you think its just probably going to just have some "non" typical format , something the Original software was meant to read? I was hoping since it was original on a computer would be standardized in the "nmea" data .
Do you foresee and possible things i could damage on the Arduino by trying it ,, don't care about the GPS since its old and unused ?
Thanks, I try to come up with interesting/useful designs based on forum discussions.
Latest are these Relay shields with up to eight 5A SPST relays for switching AC or DC with "relay closed" indicators and a couple different ways to power the relay coils.
Haven't put a price together for them yet.
If the data is coming out via the SPI pins, then yes, very non-typical. SPI is a Master-Slave interface. Is the Arduino the master? Is it reading registers in the GPS? What addresses are being used? etc. Going to be very difficult without data on the device and the interface.
DANG with all those Relay you have to have $20 just in BOM then the board ,, hm a 16 channel is around 20-30 , but thats one Awesome looking board,,, . if i just hook it up . do you think i can read the data VIA Serial monitor . if so what do you think i could expect , or should expect ? thanks
ya im thinking if i use those tx/rx pin on that chip. and hooked it up VIA the arduino ...... it would be just like hooking it up through the USB port directly ,, with no gain. and no use info for the arduino
