I mentioned in a previous article about the information on outputting waveforms using the MDK built-in logic analyzer. I found that some people are interested in using the MDK built-in logic analyzer to implement waveform output. Below, I will use the STM32F334 DAC module to output an arbitrary waveform and display the waveform using the … Read more
Scan to follow "Learn Embedded Together", learn together, grow together. 1. What are the differences between STM32F1 and F4? Different cores: F1 has Cortex-M3 core, F4 has Cortex-M4 core; Different clock frequencies: F1 has a clock frequency of 72MHz, F4 has a clock frequency of 168MHz; Floating-point operations: F1 has no floating-point unit, F4 does; … Read more
Someone used the STM32F4 chip to validate the SPI functionality. When using two on-chip SPI modules for transmission and reception based on interrupts, it was found that there was always a loss of received data, seemingly losing the last 2 data points. The code used the HAL library’s API functions. What could be the reason? … Read more

Communication protocols designed for embedded devices typically fall into three categories: Considering the limited memory and computing power of embedded devices, fixed binary is the preferred communication protocol. The following analyzes the characteristics that embedded device communication protocols should have. Simplicity Ensuring that the protocol is a simple solution is crucial; complexity often leads to … Read more
Yesterday, Xiaomi released the Civi 4 Pro, which is also the first model equipped with the Snapdragon 8s Gen3 processor. How does this Snapdragon 8s Gen3, which is a “fraternal twin” of the Snapdragon 7+ Gen3, perform? Here are the performance metrics of the Xiaomi Civi 4 Pro, the first device to launch with this … Read more
