STM32 with the Arduino Core

10 Lektionen in dieser Stufe

1. ARM Cortex-M versus AVR: What Changes for Your Code
   Compare word size, memory model, speed and peripheral richness and their effect on existing sketches. · Lab: Run a timing benchmark and print type sizes on both architectures.
2. Setting Up the STM32 Arduino Core and a Debug Probe
   Install the core, wire the SWD probe and upload reliably. · Lab: Flash Blink over SWD and identify the chip's flash and RAM size.
3. Clock Tree, Alternate Pin Functions and 5 V Tolerance
   Read a pin table to choose pins for each peripheral and avoid damaging non-tolerant inputs. · Lab: Remap a serial port to alternative pins and build a pin plan from the datasheet.
4. 12-Bit ADC, DAC and Hardware Timers on STM32
   Use higher-resolution analog and flexible timers through the core's API. · Lab: Generate a waveform with the DAC or timer PWM and read it back with the ADC.
5. Step-Through Debugging with Breakpoints and Watches
   Halt the processor, step through code and inspect variables and registers. · Lab: Find a planted bug using breakpoints instead of serial prints.
6. Hard Faults: Reading the Stack Frame to Find the Cause
   Interpret fault status and the stacked program counter after a crash. · Lab: Trigger a null-pointer fault and locate the offending line from the fault handler output.
7. Native USB: Appearing as a Serial Device or Keyboard
   Use the chip's own USB peripheral for virtual serial and HID functions. · Lab: Make the board enumerate as a serial device and then as a one-key keyboard.
8. Calling HAL Functions from a Sketch for DMA Sampling
   Reach beyond the Arduino API to vendor functions for high-speed data transfer. · Lab: Capture a block of ADC samples at a fixed high rate into a buffer using DMA.
9. Independent Watchdog, Reset Causes and Backup Registers
   Supervise firmware with a hardware watchdog and keep small data across resets. · Lab: Report the cause of the last reset and count watchdog resets in a backup register.
10. Porting an AVR Project to STM32 Step by Step
    Plan and execute a port covering pins, timing, libraries and voltage levels. · Lab: Port your data logger or controller and verify each feature against a checklist.
