I am trying to understand the flash writing code I found in the EEPROM emulation (https://github.com/PaulStoffregen/cores/blob/master/teensy4/eeprom.c) and the flasher4 OTA code.

A lot is going on...

Thanks, it works now :o

Thanks to clarify. I think it could still be useful for my purpose. With those parameters and the online test it looks to correspond with the CRC32 MPEG-2 variant.
I am wondering though, if I double...

I was looking into using the DCP to efficiently calculate CRC32 checksums. However, I can't really find documentation on how to configure and use this peripheral. The "i.MX RT1060 Processor Reference...

Okay, I peeked in Wire.cpp and see what you mean. I'm a bit surprised why it would need interrupts at all, since the Wire read/write methods are supposed to be blocking anyway?

I'll solve it with...

I'm trying to read data from a ST L3G4200D gyro, which is connected via 2-wire I2C to a Teensy2, on pins D0 and D1. I'm using the L3G library from https://github.com/pololu/l3g-arduino for...

The PSU also feeds 144 WS2812B LEDs and an USB Host Shield with Xbox controller attached, so there is definately some idle load.

I suppose looking at it on a scope would be best, but I don't have...

That is possible, but the POR circuit is supposed to keep the uC in reset until a high enough voltage V_lvdl of 1.6V is reached? The minimum supply voltage of the MK20DX128 is 1.71V according to the...

Yes, I got the power supply from here: http://www.ledsee.com/index.php/power-supply-s-adapters/150w-power-supply-5v-detail

I can try to find a manufacturer name when I'm back home.

I'm using a Teensy 3 in combination with a 150W 5V switching PSU. When I power the Teensy from this 5V source, it doesn't do anything when switching on the PSU. It does work however when I first...
