Most common baud rates table

 

The following table shows the most used baud rates. The left side part of the table shows speed and bit duration. The right part shows real transmission speed assuming there is no parity, 8 data bits and one stop bit.

What is the ESP32 VSPI / HSPI

 The ESP32 integrates four SPI peripherals. SPI0 and SPI1 are used to access the ESP32’s attached flash memory and thus are currently not open to users to be used . They share one signal bus via an arbiter. SPI2 and SPI3 are general purpose SPI controllers, sometimes referred to as HSPI and VSPI, respectively. They are open for use. SPI2 and SPI3 have independent signal buses with the same respective names. Each bus has three CS lines to drive up to three SPI slaves.

How to program 8051 based MCU using Ptroteous Schematic capture and Source code editor to use timers using AT892051 + project files

 This tutorial is dedicated to use a 8051 based Microcontroller core and program it using keil's C51 tools on the Proteus Source code editor.  1- Brief History of 8051 one of the first microprocessors 4004 was invented by Intel Corporation as well as  8085 and 8086 microprocessors back in 1981,shortly after Intel introduced an 8-bit microcontroller called the 8051 . It was referred to as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two timers, one serial port, and 4 ports (8-bit wide), all on a single chip. When it became so widespread, Intel allowed other manufacturers to make and market different flavors of 8051 with its code compatible with 8051. It means that if you write your program for one flavor of 8051, it will run on other flavors too, regardless of the manufacturer. This has led to several versions with different speeds and amounts of on-chip RAM. 2- Features of AT892051 Microcontroller Compatible with MCS®-51Products 2K Bytes of R
