January 24

Dear Reader,

January is almost behind us, and the year is already off to a strong start. It’s a time to take stock of the progress we’ve made, the ideas we’ve explored, and the momentum we’re building for what lies ahead.

As the days begin to lengthen and routines settle in, many of us are finding clarity and focus to tackle the goals we’ve set for this year. Join me as we reflect on the lessons of this first month and look forward to the exciting opportunities still waiting to unfold in 2024.

I'm also excited to continue our partnership with Mouser Electronics , a collaboration that consistently adds value to our shared explorations.

At your service!

Say goodbye to 8-bit MCUs—the STM32C0 is here to transform your projects

Looking to move beyond 8-bit MCUs? The STM32C0 series from STMicroelectronics brings 32-bit power to cost-sensitive, compact designs. Built on the ARM Cortex-M0+ core, it’s perfect for upgrading legacy systems while staying simple and efficient.

I focused on programming the STM32C011 using the Arduino IDE and stm32duino tools. Here’s what I did in a recent test:

1?? Code Setup: I used the Adafruit Neopixel library to create a simple RGB LED rainbow effect.

2?? Firmware Flashing: The internal bootloader made flashing the firmware quick and hassle-free.

3?? Result: After flashing, the LEDs lit up beautifully, demonstrating the microcontroller’s ability to handle real-time tasks effectively.

The STM32C011 proves that entry-level doesn’t mean compromising on quality or functionality.
