By chance, I learned about the sample application information in the QQ group. I have been using PIC and DSP before, and I want to try a single-chip microcomputer. It is said that the performance is g...
This is a coincidence. I used to know Kirchhoff's laws, so I never connected two batteries in parallel, always in series! Until one day, I saw a circuit diagram in someone else's article. There were t...
I'm using BQ76940 now. I disconnected the highest level and found that the chip still has power, and the 3.3 of the chip is still there, and the I2C communication is also normal. I would like to ask t...
introductionThe DZW02 220V series rectifier modules developed by our company are widely used in power supply systems. Through full-bridge phase-shift high-frequency conversion and the use of high-qual...
Hello everyone~~ I recently got this product, but many things are still unclear. The current project I want to achieve is: 1. Install four LED lights and flash different lights in turn through the PWM...
I would like to know the relationship between the data written by the microcontroller to the RXFIFO of the cc2420 through the SPI bus and the packets sent out by the cc2420. Thank you!...
