Achieve the absolute pinnacle of microcontroller efficiency by offloading the entire UART communication workload from the CPU to the Direct Memory Access (DMA) controller. This guide…
Building upon the fundamentals of polling mode, this next section transitions to using Direct Memory Access (DMA) to handle the data stream. By offloading…
Eliminate the CPU bottlenecks caused by blocking transmission loops by shifting to an interrupt-driven UART architecture using Low Layer (LL) drivers. This guide demonstrates…
The I2S (Inter-IC Sound) peripheral on the STM32F407 Discovery board provides a dedicated, high-performance synchronous communication interface designed specifically for transmitting digital audio data…
Establish robust, asynchronous serial communication by leveraging the STM32F4’s USART/UART peripheral configured with Low Layer (LL) drivers for maximum data throughput and minimal execution overhead. This…
In this seventh part of the guide, we implement Mongoose OTA (Over-The-Air) firmware update functionality to allow the STM32 to receive and install new…
In Part 2, we dive into the core firmware development by establishing $I^2C$ communication to read the factory-calibrated coefficients and raw data from the BMP180 sensor.…
Break away from continuous polling loops by utilizing the STM32F4’s External Interrupt/Event Controller (EXTI) to capture asynchronous hardware events instantly. This guide demonstrates how to map…
By offloading time management to the SysTick timer interrupt, you can replace blocking delays with a non-blocking, interrupt-driven time base that keeps your CPU free…
In this sixth part of the guide, we configure the STM32 system to synchronize its internal time with an NTP server over the network.…
