Introduction nRF24.L01 is a new type of single-chip RF transceiver device that operates in the 2.4 GHz to 2.5 GHz ISM band. It has built-in functions such as a frequency synthesizer, power amplifier, crystal oscillator, and modulator, and integrates enhanced ShockBurst technology, allowing the output power and communication channels to be configured via programming. This … Read more
IIC IIC (Inter-Integrated Circuit) bus is a two-wire serial bus developed by PHILIPS for connecting microcontrollers and their peripheral devices. The I2C bus transmits information between the bus and devices using two lines (SDA and SCL), enabling serial communication between the microcontroller and external devices or bidirectional data transfer between the master and slave devices. … 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
With the continuous updates in hardware architecture, oscilloscopes are no longer just instruments for ‘oscillography’; protocol decoding is a typical representation! IIC, SPI, UART, CAN, LIN… we have equipped the ZDS series oscilloscopes with up to 37 protocol decoding analysis plugins for free. Where are these many protocols used, and how are they specifically utilized? … 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
