Hardware Installation 1. When supplying power through the USB interface, if the USB data is connected, the APM will cut off the communication function of the data transmission interface. Therefore, please do not use both data transmission and USB cable to debug APM simultaneously. The USB interface has a higher priority than the data transmission … Read more
Working Principle The FSEU controls the flap position indicator (gauge) based on data from the flap position sensors. The data from the sensors serves as input values for flap asymmetry. When the angle difference (scissor difference) between the two flap position sensors exceeds 9°, it triggers a flap asymmetry alert. The flap position sensor is … Read more

Click the blue text to follow Optimizing ADC sampling accuracy is a key skill in microcontroller development, especially when processing sensor data. An inaccurate ADC sampling result can lead to system failures, such as significant errors in temperature sensors, causing devices to overheat or become too cold. Today, let’s discuss how to improve the accuracy … Read more
Whether for consumer electronics, industrial control, IoT devices, or for communication networks and automotive electronic systems, Power Management ICs (PMICs) are a critical part of the system. PMICs contain a large number of analog circuits, and due to uncontrollable factors during production, the final mass-produced analog circuits may differ from the initial design, affecting the … Read more
Advantages of Yokogawa EJA Differential Pressure Transmitter! 1. Simplified System Composition The EJA differential pressure transmitter only requires simple settings to obtain an output signal that relates to the input differential pressure signal’s square root. This eliminates the need for the square root element used in differential pressure flowmeters, thereby simplifying the composition of measurement … Read more
