I've been using a 485 hardware delay-free circuit recently, but there are some problems in actual use.When using a logic analyzer to analyze data (from top to bottom, TX, DE, TE, and RX), after the Mo...
In RS232 serial communication, the sampling clock frequency is 3 times the baud rate, and the requirement is to sample at both the rising and falling edges of the clock. Therefore, there are 6 sampled...
Take the subway, the elevator broke down. Take the train, there was a rear-end collision. Take the bus, it caught fire. Drink some water, Nongfu Spring has maggots. Eat some meat, Bajie is more expens...
In the previous section, we introduced the most common and most expected method of controlling WS2812 with STM32, which is to use PWM to control the signal and transmit the array data through DMA to e...
