Re: Invensense MPU60x0 gyro/accell/imu register map

Given the large number of views on this thread, I'd say there's a great interest for the register document, but we're all kind of in the same boat. It had occurred to me that one could sniff the I2C traffic on the evaluation board to gain some insight into the register map, but given the complexity ...

Invensense MPU60x0 gyro/accell/imu register map

Hi folks,

Has anyone had any success requesting the register map document for the MPU60x0 from Invensense? I'm not sure why they wouldn't include this in the datasheet!

thanks,

Re: Looking for TFT-LCD panel

This is just an aside, but you wouldn't happen to have the model number for the one that was discontinued, would you? I'm using a 2.8" OLED in a design (the one that vision opto sells), and would be very interested to hear if it's no longer being manufactured!

Re: MICROMAG 3 and Texas DSP TMS320F28335

Hi there,

I posted some code for the MicroMag3 a while ago, maybe it will be of some help? It's for a dsPIC, but the general code still might be helpful to you:

Re: Electronics Goldmine Camera

If you google the part number on the assembly, "7289123N09", it seems to show that it's for a Motorolla V551/V555 phone, which has a VGA camera in it. A bit more googling might reveal the specs for the camera, now that you know the phone it's in!

I think that's definitely the case, inventore123. If the +5/-5v are applied to the display and it remains uninitialized (with just pure white being displayed) for any period of time, it gets /extremely/ hot, in my experience. After it's initialized, and things are put on the screen, everything seems...

Replies: 8
Views: 30705

That's a good question, and I'm not actually sure. I remember some power supplies (and some ATX to bench conversions) would use a load resistor on one of the lines (5V, was it?), otherwise the power supply might not turn on. I personally haven't had any issues with this, but perhaps someone with mor...

Breakout: ATX as a bench supply

Hi all, My Dad has made a really neat and simple breakout for an ATX supply to be used as a bench supply. Lots of folks use ATX supplies as bench supplies, but usually stick the binding posts for power on the supply itself. That's a great way of doing it (we do that too ;) ), but if the supply goes ...

hi inventore123, i've just checked my e-mail, and i think it was the "C0280QGLH-T" model that i've been using. i think all the models are very similar, except for some slight mechanical differences (like no metal casing, or different heights, etc) -- but that's just a guess :). best of luck! silic0re

Hi there,

This is just a quick thought and probably not of much help, but have you tried setting your TRIS and analog to digital converter registers such that the I2C pins are set to digital I/O's and the appropriate pins are set to in/out?

That looks like fantastic work Pantheron, very well done. I'm also very glad to see that other folks have made successful use of these displays :). It looks like we both have very similar projects, I'm also using an ARM on the board that I designed with the parallel interface. Out of curiosity what ...
