Hey, we built stuff today. Two new jGPSv3 (or v3.1?) boards are nearly ready for use. The fancier COTS Venus 838 chips we added in this build have a special mode for aircraft use and provide up to 50 position updates per second.
What is done: * Stuffed * Baked * Cleaned * Connectored * Smoke-tested Still needed: * We are short one voltage regulator for the CPLD, so board #3 won't really be complete until that part is ordered. Back when we were debugging the first board, I tried to lift a leg on the regulator to test some weird thing with the CPLD and the leg lifted out of the package. * I programmed the STM32 on both new boards. They did their fancy bootup light show known as "whoop-whoop" with the terribly dim amber Cylon. The PHY came up and I could ping it. But no UDP traffic came my way. It looks like my toolchain/Chibios still isn't quite right. So we need Theo to program these boards with his setup. * I programmed the CPLD on board #2 without error. Testing will be easier with working code on the STM32. * I tried holding Boot Select high and resetting the Venus 838, but didn't get the amber light of life on either board. -- Kenny -+---+++-++-++++--+------+-+-++--++--+-+-++--+++-++----+-++-+++---+----+--+----+ On Wed, 2015-06-17 at 11:47 -0700, Andrew Greenberg wrote: > Hi everyone, > > The Venus838 GPS receiver ICs are in, which means we're now ready to > stuff our two remaining jGPS receivers.
