The Meridan/P and more info on HomeTerm
I have a Meridan/P from Device Solutions but never given it a propper introduction. The Meridan/P has the same connections and powerfull functions as it’s bigger brother the Tahoe II but in a smaller package (50mm x 50mm). It lacks the screen and the ethernet connection but both can be added externaly should be needed. The pinout of the connectors match up with the connectors on the Tahoe II so converting your project to this new board is easy!
I use the Meridan/P in my HomeTerm project now as external temperature sensor. The baseboard (Tahoe II) is connected to the Meridan/P with Xbee. The Meridan/P also controls an RGB LED matrix allowing you to put the temperature sensor in sight. The baseboard sends the current time and external temperature from Yahoo Weather to the Meridan/P and in response to that it sends the current room temperature back.
An overview of the Meridan/P:
- Freescale i.MXS ARM920T at 100MHz
- 8MBytes SDRAM
- 4MBytes Flash
- USB Function for application download and debug
- 2 Serial Ports: 1 logic level + 1 RS232 level
- SPI
- I2C
- PWM
- Ethernet available with optional add-on board
- TFT LCD controller
- Button and LED accessible from application code
- 27 GPIO pins – all can be configured as interrupts
- Power via 5V or 3.3V
- All signal available via 0.1″ headers
I think everybody will like it. More information about the Meridan/P can be found on the Device Solutions blog:
