Hello all, I tried to interface my gps, i.trekz1 solar Bluetooth datalogger, using the NXC. No luck there. Wonder if anyone has played with that at all. (17 years ago, 17-Jul-07, to lugnet.robotics.nxt)

I'm working on a custom firmware with a new VM. I'm currently trying to reuse the NXT-G memory pool to hold data for the new VM, but I'm running into problems. Apparently, doing a memset to set all of the pool to 0x00 causes the firmware to crash. (...) (17 years ago, 16-Jul-07, to lugnet.robotics.nxt.nxthacking)
