How long (in milliseconds) does it take to serial transmit (using TX and RX hardware serial on Arduino Uno) 2 integers, 3 floats, and 2 characters all converted to a string when using 2400 baud?

gfvalvo: 1 Start Bit + 8 Data Bits + 1 Stop Bit = 10 bits per data byte transmitted. 2400 bits / second How many bytes you sending? 2x2+3x4+2x1=18 bytes. So from your post: 180 bits. Overhead: I think none except stop, start and parity. Delimiters: none as far as I know, edit: one start and o…

Each bit is 1/2400 seconds 180/2400 =

The rate for transmitting bytes is about 1/10th of the baud rate because an 8-bit byte needs 10 bits to transmit when you count in the start and stop bits. So 2400 baud is about 240 bytes per second. ...R

Assume asynchronous frame length is 10 (1 START Bit, 8 Character Bit, 1 STOP Bit), the transmission times for -- 1. 1 integer type data (0x0000 - 0xFFFF) : 4x10x1/2400 = 16.67 ms 2. 1 float type data (binray32 format) : 8x10x1/2400 = 33.33 ms 3. 1 character type data ('A' = 0x41) : 1x10x1/2400 = …

brice3010: 2 integers, 3 floats, and 2 characters all converted to a string when using 2400 baud? brice3010: 2x2+3x4+2x1=18 bytes. The first would be true if you would just send the varaibles. But you say you convert it to a string so you're not... A int can have anywhere between 1 (for exam…

septillion: The first would be true if you would just send the varaibles. But you say you convert it to a string so you're not... A int can have anywhere between 1 (for example '5') and 6 (for example '-32768') characters :wink: For a float it even depends on the number of decimal places you tell …

brice3010: Are bitrate and baud rate the same, as I read differently? Absolutely different, but have become interchangeable with the demise of telephone modems. Baud refers to the sine wave of the tone used to send data via modems. The old 300 baud and 600 baud modems encoded one bit per single…
