In the fourth part of our STM32 Low-Layer (LL) I2C series, we offload transaction overhead from the CPU by implementing Direct Memory Access (DMA)…
In this new series guide, we shall emulate the UART hardware using a clever combination of timers and DMA to achieve effortless, CPU-independent serial…
In this third installment of our STM32 Low-Layer (LL) I2C series, we shift from receiving data to actively configuring slave peripherals by updating the…
Establishing reliable bidirectional communication is the foundational step in validating the sensor emulation framework, ensuring that the master device and the emulated sensor can…
For the second part of our series, we transition from bus scanning to active data retrieval by interfacing with the highly accurate DS3231 Real-Time…
UART-based sensor emulation on an STM32F4 provides a cost-effective and highly controlled method to validate data processing algorithms and communication protocols without requiring the…
Mastering the I2C protocol at the register level offers unparalleled control and efficiency, especially when navigating the specialized Low-Layer (LL) drivers provided by ST.…
Eliminate the CPU overhead of processing individual incoming characters by offloading variable-length UART reception entirely to the DMA controller. By pairing a circular or…
Now that the basic DMA transmission pipeline is established, the final part of this guide focuses on interfacing the STM32F407 with the onboard CS43L22…
Efficiently parse variable-length incoming data frames by combining UART receive interrupts with the hardware’s built-in IDLE line detection feature. This architecture uses the Read Data Register…
