MechatronicsLLC commented on Paul Mather's blog post MAVlink frustrations--how do I calculate a crc16 checksum in VB.net?
"Happy -

We use the below for CRC32 in VB.net. You might be able to adapt it for CRC16. It is a function call that is called per the following:

Dim CRC32 As Integer
CRC32 = XsumCRC32(&HFFFFFFFF, doitbyte)

where doitbyte is a byte array with the…"

MechatronicsLLC replied to Bill Nesbitt's discussion UBlox 5: Velocity & Position actual timing
"Hi Bill,

The timepulse pin isn't primarily for time tagging the messages. They keep the jitter of the pulse (nominally 1 pulse per second) as low as possible so that you can sync / calibrate your hardware. This can be used to keep two different GPS…"

MechatronicsLLC replied to Jason's discussion IMU wing leveler
"Hi all,

We had originally thrown this module together: Analog Node

To use with our CHIMU AHRS to do what you are talking about. Its a little pricey for this group (the unit uses magnetometers instead of GPS for yaw) and no open source, but...…"

MechatronicsLLC commented on Pete Burnight's blog post I2c GPS frees up Serial Port
"We make an I2C board with Ublox, mag and tilt sensors on it. The whole cost is probably too pricey ($195), but we have 4 boards that have non-functional magnetometers that we will offer up at a lower cost. These allow direct communication to the…"
