STM32 Short #6 - STM32World Micro-SD Module

In an earlier video we went through the design, production and use of a Micro-SD Breakout Board. At the same time we ordered that board, we also made a board for our STM32World modular development boards. This video describe and test that module. We also cover how to put in a large order at JLCPCB.

STM32 Tutorial #64 - Proper SD Breakout Board

In some earlier videos we used SDIO and SPI to access a FatFS on a SD Card. In those videos we used a quick and dirty hacked together breakout board created by soldering some wires of a SD to Micro-SD adaptor.

Second iteration is assembled! Definitely some more work to be done to sort out UCPD issues. I am still wrapping my head around the CC and CCDB pins. Some preliminary bodges show promise. I think we will be able to start working on the software with @dragonmux soon after the bmputil V1.0 and Black Magic Debug V2.0 release. :D (DISCLAIMER: this is a long term project, don't hold your breath. If you need a BMP get the V2.3) #electronics #debugging #jtag #swd #mcu #stm32

Looks like I *might* need an #STM32 for a professional project. I just have to pick an MCU, what could go wrong?

Hahahaha. Fool!
There’s no online product finder.

Instead, there’s a proprietary desktop app for that, and you’ll have to leave your e‑mail address before you can download the sub-par, 280 MB installer.

Aaaaaand the app is a piece of crap. Slow, ugly (no anti-aliasing)… and no proper search engine.

What the actual fuck, #ST?
Are there any workarounds?

STM32 Tutorial #62 - STM Mystery MCU - final solution
We have done a few videos about the mysterious non-existing STM32F402 MCU (Chinese market only MCU). In an earlier video we speculated that it was in FACT a STM32F401. Having received our STM32World STM32F402 development board, we finally get to put this theory to the test! Watch the video to learn the secrets of this MCU.

@oshpark boards in today! This is a USB/CAN-FD adapter, to start working on CAN-FD support in #zencan. It's an stm32g0 + TCAN1044.

I'm also considering standardizing on these JST XH connectors for CAN stuff, mainly b/c they have these right angle board-to-board plgus to make PCB "T"s or terminators. The friction fit is pretty good? But I'm a little worried about wiggling loose over time in a vehicle. Interested in other connector suggestions for this...

STM32 Tutorial #61 - STM32CubeIDE Tips & Tricks

Is STM32CubeIDE good or bad. It would appear that a lot of people love to hate STM32CubeIDE (or any other Eclipse based IDEs). In truth, CubeIDE is a bit quirky, but it is also immensely powerful and in general it works really well.

STM32 Unboxing #1 - JLCPCB Goody Bag

My first (!!! - and possibly last) unboxing video - didn't go particularly well. Recorded on my phone on my balcony - audio is pretty horrible and for some unknown reason out of sync. Anyway - the box was full of Goodies from JLCPCB (described in last video). PCB's ordered last Monday and I had them today - exactly 1 week later.

Timer Input Capture

In this video we'll be revisiting timers. In a much earlier video we were using Timer Input Capture to decode rotary encoders. In this video we will be using input capture mode to measure frequency and duty cycle of a pulse width moduleated input.
