![]() ![]() I had pretty good success with my 8bit flyingthing using analog Invensense gyros and ADXL accel. So you can't get a CopterControl even if you really wanted to, though demand has been slightly reduced by people buying DJI Naza and selling off their CopterControls ![]() Openpilot is still failing to meet demand, having production troubles (again), is in the middle of switching gyros on CopterControl, and Revolution platform is still being worked on. Timecop car how to#It would be cool if those guys could eventually figure out how to do PPM input and how to set ESC arming pulses to 1000us and not whatever they're doing. Maybe the Atmega32U they're using for USB interface.ĭJI released their "hobby" version of WK-M and promptly overpriced it. They're not even using MPU6000 DMP/sensor fusion stuff, it's still same ol' tarduino/AVR for main processor, and I dunno what butt they're pulling the 3rd processor from. Then there's the lies about "3 processors". Timecop car full#A new form factor, but still full of headers and heavy/ugly. A minor sensor refresh, switching to all-digital sensors (more on this later). But let's take a look what it offers? Same old obsolete 8bit processor. Tardupilot Mega 2 has been released and is solid unobtainium. Remember blog last year about lack of innovation in multirotor scene? Well, nearly a year later, and nothing changed. This is going to be pretty much against everything I've been posting here for the last year but hey, if it works, ship it! There's also an AD7997 10bit, 8 channel ADC with I2C bus, which is probably used for battery voltage monitoring (the ADC on AT91 must really suck). It's loaded from Altera EPCS1N config flash, and driven my 50MHz oscillator. It could also be running the actual IMU fusion code, who knows. Timecop car code#There's also an Altera Cyclone EP1C3T100C8 FPGA, it's purpose isn't really obvious (at first I thought code / firmware protection but that's not the case), maybe it's used for PWM generation/capture. Of interest is 3 FETs for driving RGB led strip near the bottom center of mainboard.īottom side is a bit more interesting, containing the main processor (Atmel AT91RM9200CJ), a 180MHz, 32-bit ARM920 MCU with 64Mbyte external SDRAM (HY57V64162) and 4Mbit Atmel DataFlash for firmware (AT45DB041D). The rest of components are passives/crystal/headers. Unlike DJI, Y6 MC communicates using RS232 - so there's a Maxim MAX3243 3/5 channel TTL>RS232 converter. Top side of main controller contains the LM2596 SimpleSwitcher DC/DC module for taking battery voltage down to 5V levels for the rest of electronics. Here's some details about the ZeroUAV YS-X6 system: Hopefully some people find the info useful. So instead of letting the pics rot, I figured I might as well post it. I've had this stuff around for a while, but had no time to write stuff up. ![]()
