GPS 2.0This is an ongoing project to build a handheld GPS device. I chose a board with an 8051 chip due to its low power requirements, support for rs-232 level signals as well as I2C, and a large amount of on board flash ram.The board interfaces with a character LCD, and the same GPS board used in my first GPS project. It records GPS data and uploads it to the computer for display. At the current state of the project it has trouble support i2c and rs-232 at the same time, and I need to write a program to process the data on the host machine. |
