    First WiFi Loco-Nodes, ready for fabrication/assembly

    https://www.youtube.com/watch?v=LPGMcAJWEPU&feature=youtu.be All 11 of 11 nets are up for FX LED as seen in the video, we have something ready for the 4 PWM channels, I should be able to post a demo soon of it Today we got another UX file that is updated with more navigation enabled I also...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    We have 10 of 11 FX_LED nets switching now by eliminating driver overlap. One more to go. Tomorrow we are going to start the WiFi network configuration and antenna testing

    First WiFi Loco-Nodes, ready for fabrication/assembly

    we got the battery charger status inputs working with the ADC, this gets us past 83% the inputs go HIGH/LOW depending on FAULT and CHARGE status to test, we ran a demo program, then applied rail input voltage, the CHARGE pin went low to indicate charging of the Li-PO next up is the WiFi...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    The Battery Fuel Gauge is taking I2C commands, we're now setting it up to test voltage, temperature, current, and level. This puts us at 77% complete all hardware testing. www.layout-ioe.com

    First WiFi Loco-Nodes, ready for fabrication/assembly

    We tested the PWM outputs on FX_LED and they work The program we ran is not set up for a good dim effect yet, but the change is noticeable when compared to another LED This signs off a major component for the Loco-Node harware Will post images, video, when able www.layout-ioe.com

    First WiFi Loco-Nodes, ready for fabrication/assembly

    FX LED is based on 16 bit logic with 4 PWM channels for special effects like Dim, Mars, Gyra, and Strobe It will also support Green, Amber, or Red LED's without the need for external resistors The board has 11 pads per end, the pads will support 64 or 128 mA each www.layout-ioe.com

    First WiFi Loco-Nodes, ready for fabrication/assembly

    I got a patch so we can use V1.4 for demo and sound software development but I will still go with V1.5 for shipments

    First WiFi Loco-Nodes, ready for fabrication/assembly

    I found one small bug in the SPU - Amplifier connection, a capacitor is going to ground when it shouldn't so its not filtering the DC part of the DAC signal That's why we can control the amplifier, it seems to work perfectly, the software works but the audio from the speakers is missing even...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    More progress - slow but we're moving forward The Linux Kernel has been reduced to the lowest practical size and is now opening consistently with a console, BusyBox The I2C bus has been tested and works We are able to change the Gain, Volume, and other settings through I2C on the stereo...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    We got a new software patch this morning from Micron, its compiled without error - we just need to integrate it Enough of the hardware tests to sign off the Generic Node (GN-S605) is completed. This node is $59. It has the WiFi, the CPU, 4GB eMMC, voltage regulator and diode bridge to handle...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    More progress today: 1) We found some errors in the driver patch Micron sent us for the flash, we sent them back - should get something in a few days to fix this 2) I retested FX LED. All non-PWM pins are switching OK. This only leaves four pins not working and means its a software issue, we...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    We got the BusyBox bug fixed, it hasn't been coming up since we got the sound demo ready and flash driver into the file - so we can continue hardware testing this week After the file is cleaned up and the debugger info is removed we can test the sound and battery fuel gauge Then we have some...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    I spent the day going through the flash driver code and we got it up and running, now BusyBox went down again a few days ago but after comparing UART outputs, its the only thing missing - on the 17th it came up perfect The last thing to modify with the flash is ensuring we can read/write it in...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    about 75% of the systems are now tested the FX_LED issue has been traced to a soldering defect we can fix and eliminate with tighter QC, everything else so far is OK we have semi-working drivers now for the sound amplifier, battery fuel gauge, and flash, still debugging motor drivers and...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    We cleared up the crashing issue, just waiting on some responses to finish the flash driver and BusyBox is back in now as well. There will be some end user functionality, I just haven't got to that point yet to figure out what and how we can implement it. My main focus right now is wrapping...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    Ilya got a driver working for the flash, it has bugs but this was the very first attempt with this file today after many failed attempts yesterday I also got confirmation that there are no fabrication faults on FX_LED so I got a new board wired up tonight to finish the tests on it If we can...

    First WiFi Loco-Nodes, ready for fabrication/assembly

    some updates on progress. we're getting some direct help from Micron on the flash, we've tried all of the drivers and it still only works (with wrong information) using the generic driver most of the UX is not done, its just adding the back end and navigation, user settings will be working...
