SDO (Service Data Object) is a type of message in the CANopen protocol used for reading and writing data over a CAN network. SDO is used to transmit data that is not time-sensitive, such as configuration information that only needs to be set once during initialization. There are several types of SDO transmissions: SDO Download … Read more
OD (Object Dictionary): This is an ordered, predefined group of objects that can be accessed via the network, with each object addressed by a 16-bit index and an 8-bit sub-index. The range of a node’s object dictionary is from 0X1000 to 0X9FFF. COB-ID (Communication Object Identifier): This is the message frame ID of the CANopen … Read more
In industrial communication scenarios, both LoRa and ZigBee wireless communication technologies are widely used. However, during the application process, we often find ourselves confused about the calculation of their communication time. Today, let’s understand how their communication time is calculated together. Product Prototype GxCOM-NET is an intelligent LoRa | ZigBee data communication box independently developed … Read more

Does IIC support hot swapping? (With a detailed interpretation of CW32 IIC protocol) Have you learned it yet? After I finish these low-speed experiments, I will provide the debugging steps for the logic analyzer. IIC is done, next comes SPI, which is worth highlighting because the vast majority of devices use SPI; it’s practically ALL … Read more
01 【SPI Concept】 SPI (Serial Peripheral Interface) is a synchronous serial port for communication between microcontroller units (MCUs) and peripheral ICs (such as sensors, ADCs, DACs, driver chips, and external storage devices). The communication rate can range from a few thousand bps to hundreds of Mbps or even higher, depending on the specifications and performance … Read more
