What is serial communication in computer?
In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.
What is an example of a serial communication protocol?
Similarly there are several examples of Serial Communication Protocols such as CAN, ETHERNET, I2C, SPI, RS232, USB, 1-Wire, and SATA etc. Serial communication is the most widely used approach to transfer information between data processing peripherals.
What is the purpose of serial port?
A serial port is an interface that allows a PC to transmit or receive data one bit at a time. It is one of the oldest types of interfaces and at one time was commonly used to connect printers and external modems to a PC.
How is STM32F4 connected to the USART network?
USART2, USART3, UART4, UART5 are connected to APB1 bus and able to communicate at speeds of up to 5.25 Mbit/s. To interface STM32F4 to your PC with USART, you can use either DB9 port or use USB port (Using USB to RS232 converter or USB to TTL converter).
Which is an example of STM32 serial communication?
It is a very common and basic example like sending a string to PC COM port which is covered by lots of tutorials on the web. But my question is, I first used this product and directly connected to my board’s RX TX pins and I was able to get data but all the data was a mess.
Is the STM32F4 Discovery board compatible with UARTs?
As you know, the STM32F4 discovery board comes with an STM32F407VG6T microcontroller. Like other STM32 family microcontrollers, this SoC also supports UART communication ports. STM32F407VG6T has on-chip 4 USARTs/2 UARTs communication channels.
Can a STM32F4 be used as a USB to TTL converter?
If you use USB to TTL converter then you can directly connect to the STM32F4 because most of I/O pins on STM32F4 (Especially for USART pins) are 5V tolerant. You can also use Arduino as USB to TTL converter in case when you don’t have USB to TTL converter device but you have Arduino.
