STM32G474 Encoder Index: Preserve the Same Reference Position in Both Directions
Why does a quadrature encoder index load zero in one direction and ARR in the other, and which A/B phase should define the physical reference?

STM32H750 DCMI JPEG Capture: Separate Compressed Bytes from DMA Words
How should an H750 camera receiver handle JPEG frame boundaries and last-word padding when the sensor output has variable compressed length?
-
TinyML Edge Impulse Signal Callbacks: Honor Requested Sample Offsets When Paging Input Data
Why does a fixed RAM input work while an external-storage or FIFO-backed get_data callback corrupts later DSP reads even though it returns success?
-
Rust Embedded Graphics Text Placement: Separate the Baseline Anchor from the Text Block Bounds
Why is text at y=0 clipped, and why does vertically centering the first line fail to center a multiline label?
-
STM32H750 SDRAM Retention: Enter Self-Refresh Before Removing the Memory Clock
Why does an H750 SDRAM low-power path lose data when the application stops the FMC clock after selecting power-down?
-
TinyML EON Model Updates: Identify the Compiled Inference Artifact Before Replacing a FlatBuffer
Why does replacing a .tflite file or model-byte array leave an EON-compiled MCU application running the previous model, and which artifact actually needs rebuilding?
-
Rust Embedded Graphics Borders: Measure the Styled Shape Before Placing It at a Screen Edge
Why can a rectangle that fits the display still lose part of its border after the stroke width or alignment changes?
-
STM32CubeIDE SWV Trace: Separate Clock Mismatch from SWO Packet Overflow
Why does a CubeIDE SWV session stay silent or lose trace data even though ordinary SWD debugging works?
-
STM32H563 External-Code Caching: Route Fetches Through the ICACHE Alias
Why does enabling H563 ICACHE fail to cache code fetched directly from an external-memory address, and what does its remap alias change?
-
STM32G474 ADC Oversampling: Prevent a Large Accumulation from Wrapping the 16-Bit Result
Why can enabling hardware oversampling change a G474 ADC scale or wrap a near-full-scale input rather than simply smooth the same reading?
