Serial Output returns wrong ASCII

I am using a FTDI cable and connected it with my mac. I can connect successfully with my serial terminal on my mac via the cable and can input text on my keyboard to be transmitted to the AVR. When the program starts I expect a "Hello World" message…

Can bits-per-symbol be increased by superimposing frequencies on top of one another, analogous to chords in music?

I understand how the number of symbols used can be increased with things like quadrature phase-shift keying or quadrature amplitude modulation, and so on. I have thought for a year that it would be interesting design to increase bits-per-symbol by…

How are two definitions of baud rate same?

The bit rate V baud rate has been a confusing topic for me lately. I feel like I am clear about the difference between these two. But going through the definitions of baud rate, I find two different definitions in use: A baud rate is the number of…

How do I log UART ASCI data at high speed (above 921600 baud)

I am transmitting data from a microcontroller via UART and this is going to the USB port of a laptop. The data comes formatted as ASCII, and I am viewing in real time and logging in a PC using TeraTerm. The problem is TeraTerm can only go up to…

HM-TRP radio module works at 56K data speed but only in delayed chunks

I created the following setup: I created one circuit in which the PC connects to an HM-TRP radio module via a max232 DIP IC. This circuit for the test is the master to all devices and sends a 16 byte packet to each slave in turn. The second circuit…

Serial baud calculation without using serial interrupt - 8051

Here's the situation. I have a project which utilizes multiple sensors and connects to another unit through standard UART (8N1). Because no data needs to be missed from any device, I made the multiple sensors function as wireless UART channels which…

Tolerance of SPI comms bit ratres (transmitter and clock master too fast)

I'm wondering people's thoughts on what happens when SPI timings between master and slave are "a bit" off. A bit being 2.34375 % too slow. My setup is: Slave device, which I cannot change, wants to be fed a clock of 128000. My master device, which…
