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
