STM32 Short #2 - The Mysterious 0b Prefix
In this video we will be looking at the mysterious 0b prefix in C. The mystery is that this was not part of the original K&R C definition.

Designing my first PCB in Kicad. I think I've got the power supply wired up correctly.

Design and construct a battery-powered GPS receiver and recorder with firmware and a Linux-based GUI application for visualizing the data recorded

I just finished my first attempt at a design for a schematic symbol in Kicad for an MCU (STM32N657Z0H3QTR).

STM32World Rant #1 - USELESS Development Boards

Welcome to the first STM32World Rant. In this rant video I'll go through some of the most useless development boards on the market, so that you dear viewer can avoid them.

Not sure if this will be the only rant ;) IF you like the format of this video please let me know in the comments. I can always find other things to rant about.

My latest blog post: VanSpoof v1.0

https://mikecoats.com/van-spoof-v1-0/

I'm happy to announce the v1.0 release of VanSpoof. My VanMoof X3 now starts up, without an e-shifter connected, and does not show an Error 44 status! The bike thinks it's connected to a working, functional, e-shifter!

CLion 2025.1 Arrives With Support for Out-of-Project Files in CLion Nova, Qt Renderers, the ST-LINK Debug Server, and West Build Options

STM32 Tutorial #53 - CRC Peripheral

In this Getting Started Tutorial video we are going to dive into the CRC peripheral which is included in most (if not all) STM32 MCUs.

STM32 Tutorial #52 - Flashing ST-Link and Black Magic
In this video we will show how to flash a home made ST-Link device and how to create a bootstrap for it. We will also cover switching between ST-Link firmware and Black Magic Probe firmware.

I wish the embedded ecosystem were easier to get into ;_;

My STM32 pcb won’t talk via SWD and it’s killing me. I have no idea what might be wrong

If someone has some time to spare and would want to help me I’d be super grateful

STM32 Tutorial #51 - SPI Introduction

In this video you will get an introduction to SPI.

So! PC-Zeit. Kann nun in Ruhe Nerd-Kram nachgehen.

Dann setze ich mich mal an mein Problem mit dem Debugger und meinem STM32 LoRa Chip - nachdem ich vor ca zwei Wochen endlich eine Verbindung hinbekommen habe und neue Firmware flashen konnte, verweigert das ganze Setup nun plötzlich jede Verbindung zum Chip und ich bin ein bisschen ratlos.

Meine Bewunderung geht an alle uC Embedded Entwickler. Man muss wirklich frustresistent sein - aber dasselbe sagen die ja vllt auch über Linux-Typen wie mich xD

Hat jemand von euch Erfahrungen mit verschiedenen STM32 V2 Debuggern?

Ich habe auf Ebay mal so einen gekauft: https://www.androegg.de/shop/usb-st-link-v2-stm8-stm32-jtag-openocd/

Nun habe ich das Problem, dass zum einen der STM32CubeProgrammer damit extrem instabil zu sein scheint und gleichzeitig zwar auch das Auslesen des Flash zu funktionieren scheint - aber nicht das Beschreiben. "Failed to erase memory".

Mit Fehlt damit komplett die Erfahrung. Kann so ein billiger Debugger die Probleme verursachen? Mit fehlt leider der Vergleich.

Habe dazu auch im RAKWireless Forum geschrieben: https://forum.rakwireless.com/t/using-st-link-debugger-with-stm32wle5-core-module-rak3172-module/14295

My original plan was to use the RAK11300 RP2040 + SX1262 LoRa module to transmit air temp/hum/qual. data via LoRa.

... which works... but the RP2040 does not meet my power consumption targets. I knew it was not the most energy efficient uC, but hoped the RP2040 ecosystem would balance out the power insufficiencies...

In the end I decided to switch to another uC.

RAKWireless also offers the STM32WLE5 as a WisBlock module, so that's what I will try next. [1]

For proper debugging a STLink Debugger has been purchased recently ;-) Waiting for the module to arrive, though .

ooh, a good question for the ARM MCU crowd.

what's the most precise way of syncing execution to an external signal? assume I can read from a GPIO and want to start the following instructions as precise to an edge as possible. code runs stm32f103 if that matters. latency is not an issue, but jitter is.

right now I put all the affected code into SRAM and that seems to have improved things but there is an occasional slip.

AtomVM v0.6.0 is finally out: https://github.com/atomvm/AtomVM/releases/tag/v0.6.0

For who does't know it: #AtomVM allows to run #erlang, #elixir, #gleam and also #lfe on MCUs such as the #ESP32, the #RaspberryPi Pico (2040) and some #STM32, but it also supports Linux and wasm.

Whelp, quite late to this whole #introduction thing. Long time lurker on the birdsite and trying to get more involved in the community here. I get to manage a few really smart engineers by day and hack away on and build and/or break things at night. I'm mostly a self taught nerd who is learning to balance life as a new father. I cook, I brew beer, I can occasionally design a pcb correctly on the first try, and I'm learning reverse engineering. #hamradio #homebrewing #esp32 #stm32 #raspberrypi #bourbon #grilling
