An update on this issue. @len0rd and I have completed all the hardware drivers and unit-test-like examples for all the F4 hardware peripherals we need (SPI, I2C, PWM, UART, VCP...

Okay. I have a simple example that isn't pretty, but I'm streaming IMU at 500 Hz no problem. The parameters are pretty garbled up and I'm getting tons of errors...

This depends on #85

I figured this out - It was a stack overflow due to some weirdness in the linker file. For some reason, the linker file for STM32F4 supplied in 2015 puts...

Unfortunately, it's not. I was originally really excited about the OPLink, because I thought that it was more like the 3DR radios where you basically pass it data and it...

I just leave it unplugged. Maybe that's naive, but I haven't seen any problems so far. readytoflyquads is selling a replica of the Revo that is missing the OPLink https://www.readytoflyquads.com/openpilot-cc3d-revolution-acro....

That's pretty concerning... Thanks for letting us know! Do you happen to have a rosbag of this happening? I have seen this in the past, but I thought that I...

I've just been able to reproduce this behavior. Thanks, definitely my bad - I've dialed down the `FILTER_KI` parameter to `0.01` and that seems to have fixed it. I'll try...

Thanks, that's really troubling. Let me make sure I understand - You're observing a bias when flying, but not when stationary? If you could collect a log, that would be...

That is correct, the imu rate should be 1000 hz. There is a decent chance that we could miss one or two measurements per second, but probably not in a...
