调试时总是会遇到各种各样的接口，各种各样的转换板，似懂非懂的感觉很不爽! 首先，串口、UART口、COM口、USB口是指的物理接口形式(硬件)。而TTL、RS-232、RS-485是指的电平标准(电信号)。 串口：串口是一个泛称，UART，TTL，RS232，RS485都遵循类似的通信时序协议 ...

Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...

Electronics engineer Ravinder who has been working in the embedded industry for past 10 years developing products based on Raspberry Pi, Raspberry Pi Pico, Arduino, Jetson Nano and others. Has taken ...

Our Hackaday colleague [Bil Herd] is known for being the mind behind the Commodore 128, a machine which famously had both a 6502 and a Z80 processor on board. The idea of a machine which could do the ...

Specifications of the board include UART, TTL, RS485, DAC, ADC, I2C, nRF2401 and the board offers an external plugin using 2×4 header on board. Enabling users the ability to read 2 x TTL UART and 1 x ...
