Infrared remote control protocol Wireless contactless control technology At present, PWM (pulse width modulation) of NEC Protocol and PPM (pulse position modulation) of Philips RC-5 Protocol are widely used in the coding of infrared remote control characteristic Anti interference ability, reliable signal transmission, low power consumpti ...

1. Start It started like this. This is a screen removed from the automatic deposit cabinet. It has been placed for two or three years. I want to use it. It uses a rare 22 pin foot Then it's amazing that this thing now costs hundreds of dollars. These thousands are false bid prices. The actual price should be between 2 ...

one   General timer input capture overview one point one   How input capture works          In the general timer block diagram, input capture mainly involves the top part (selection of counting clock), the middle part (time base unit) and the bottom left part (input capture). Here we mainly ...

For yuluo's sister, cough, in order to expand my knowledge, how can I only use a liquid crystal as small as my brother? Shouldn't I be bigger Linkage article The iceberg Royal Luo, who is worth more than 100 million, said to xiaomainong, can you display LCD Introduction to LCD12864 Abnormal LCD12864 LCD screen, three COB cow dung piles o ...

Transplanting neural network to STM32 A recent project needs to use the network for fitting, and use the fitting results as control. I wonder if I can do neural network calculation directly on the single chip microcomputer, so that I can calculate in real time without relying on the upper computer. Therefore, there are two main problems to be ...

ESP-NOW introduction ESP-NOW is a protocol developed by Espressif, which allows multiple devices to communicate with each other without using Wi Fi. The protocol is similar to a low-power 2.4GHz wireless connection. Pairing between devices needs to be completed before communication. After pairing, the connection is secure, point-to-point, ...
