Just found out from this video - the adapter PCB that I was using is wired wrong. So that can happen.

Hi all, I’m trying to hook a Wii Nunchuck up to a Teensy 4.1 over I2C. Using the built-in I2C scanner sketch from the Teensy Arduino examples, I can successfully detect an MPU-6050 and an OLED display. So I am pretty sure about that basic I2c...

I would add that PSRAM tends to perform much better for sequential access rather than random access, for example if you had the choice it would be better to use array style storage rather than something like a linked list.

Usually PSRAM is useful for buffers to hold data you write and then read once, or occasionally. It's especially useful for network applications, like accessing a web server which might transmit a large file, or collecting and transmitting data...

I've just installed two 8MB PSRAM chips from the Teensy store and ran the test sketch — everything appears to be working fine. I don’t come from a programming background, but in my current project, I have a time-sensitive Timer ISR running at...

So one my friend is working on drone light show project. He is using a pixhawk flight controller, which uses a mavlink protocol to communicate with a drone. Now to communicate with multiple drones, he has a rpi zero 2w as a packet router from...

This is a Mongoose product promo. Mongoose is an open source, dual-licensed network stack, https://github.com/cesanta/mongoose It implements native Ethernet drivers for various microcontrollers, including IMXRT1062. It implements OTA updates too...

Context: I have a timer interrupt running at 1 kHz that performs calculations. For these calculations, I need 6 float values, which are received over USB serial. The serialEvent() function (called at over 7 MHz) assigns values to these 6 floats...

Thanks @joepasquariello and @jmarsh . If anyone could point to a document, that would definitely help me sleep better.

I'm using a Teensy 4.1, and I have a float variable (tgtfr) that's updated in serialEvent() based on serial input. This same variable is read inside a timer interrupt that fires every 1 ms. The main loop is running very fast — over 7 MHz, based...

wdym? you are breaking my brain, I have using a 4 pin connector for ages
