Using STM32 Timer to Trigger SPI Communication with DMA When working on SPI applications, we sometimes want to trigger SPI transmission and reception periodically using a timer and utilize DMA for data transfer. Here, I will demonstrate this based on the STM32L476 chip for reference (the choice of STM32L476 is not particularly special, I just … Read more
1. What are the differences between STM32F1 and F4? Different cores: F1 is Cortex-M3 core, F4 is Cortex-M4 core; Different main frequencies: F1 has a main frequency of 72MHz, F4 has a main frequency of 168MHz; Floating point operations: F1 has no floating-point unit, F4 has one; Functional performance: F4 peripherals are richer and more … Read more
Since my last article about the issue of counterfeit STM32 chips, ST has officially supported me by providing a batch of samples, including the STM32G473, for which I would like to express my gratitude to ST. In this issue, we will design a development board using this chip. The STM32G4 series is designed for applications … Read more
