Recently, I found a few HC-12 wireless modules that I had bought a long time ago from my drawer. I intended to use them to create a wireless remote control for a small toy, but during testing, when I connected to the computer and sent data through the serial debugging tool, it froze, although receiving … Read more
Click the blue text Follow us 1. First of all, UART and TTL are completely different concepts. UART stands for Universal Asynchronous Receiver/Transmitter, which is a serial asynchronous communication protocol. The TTL level signal specifies that +5V is equivalent to logic “1” and 0V is equivalent to logic “0” (when using binary to represent data). … Read more
Concept of DMA DMA (Direct Memory Access) allows data transfer without direct control from the CPU. It creates a direct pathway for data transfer between RAM and I/O devices, significantly improving CPU efficiency. There are several methods for UART data reception: the interrupt mode of UART isthe most commonly used data transmission method in microcontrollers, … Read more
