Is it possible to use this new feature to access the GPS unit for initial configuration purposes using u -centre.
I only ask as I have been expereincing extreme difficultly getting error free communication through the FTDI cable and Tiny 2.11 uart 1 for the above purpose using an Windows XP IBM laptop.
Just in case, I have loaded the boot loader and tunnel
Martin Mueller Said:
there is a new feature that allows to use the USB port of the autopilot for telemetry transfer (instead of the serial link).
It was needed to change the peripheral clock (PCLK) in the LPC2148 to make this possible. Changing this "master" clock affects almost all hardware modules on the chip. The drivers (uart, spi, adc, ...) need to be aware of that changed clock. They have been adapted and are now able to run with different PCLKs.
Please check with caution before you fly with the new cvs code next time. If you want to review the code, please take a look at these registers/functions:
