In serial communication data is transmitted as a sequence in time. Main advantage: much less wires needed. Main disadvantage: Higher bandwidth for the same throughput.

You are confusing the voltage levels (RS-232 we assume) and the serial protocol (lets just say uart as it came from a time before everyone was obsessed with naming things). Using your example you … similar. At the end of the day you cannot have a reliable single signal serial protocol without some way to know where word/message boundaries are in the bitstream, likewise cannot do it without knowing …

I assume you are talking about a UART or serial interface, RS232 is an electrical and pin standard (simply defines what voltage levels a one and a zero are but not the state changes, protocols … have at least one serial port as that is the primary display interface for booting/debugging, etc. But I know what you mean. With the general lack of a need for RS232, usb to uart works just fine …

the next few cells on count 5 instead of 6 to fine tune the middle of the bit cell. Very typical for continuous data to keep adjusting, for serial when we typically have say 10 or 11 bits per symbol/character you can the source and receiver clocks be quite a bit off and still work well enough. …

Note RS232 is a voltage standard, it does not define a protocol. It defines what a one is and a zero, and pinouts for the connectors. As far as decoding the serial protocol on a scope, it is not … decode it yourself. You will waste a lot of time debugging something assuming the scope software is right (for any serial protocol not just a uart style protocol). As far as a serial protocol, the only …

uart serial data, but not to be confused when you say RS-232 you had better mean that voltage level carrying this data, you plug RS-232 into the uart pins on a microcontroller and you will likely fry … the microcontroller because it cannot handle those voltage levels. You can carry ip and tcp and other protocols over uart/serial, look up ppp and slip protocols for example again, you take the tcp …

Quite simple no. You do not have a clock to go with your RX data so the spi controller has nothing to clock the data with. If you were to somehow manage to use a timer to fake the clock there will b …

on a raspberry pi though to find rx and tx. note this is NOT RS232, RS232 is a line level thing not a serial standard thing. this is uart or serial but not RS232...If your other device is RS232 yes you will hurt the raspberry pi even if you wire tx and rx properly. …

generally these chips are configurable. they will boot off of the internal oscillator in case there isnt an external. then you can keep using that one or software can switch to the external. then t …

The problem is keeping the signals on a parallel bus clean and in sync at the target. With serial "all you have to do", is be able to is extract the clock and as a result the data. You can help … by creating lots of transitions, 8b/10b, bi-phase or manchester encoding, there are lots of schemes (yes this means you are adding even more bits). Yes, absolutely that one serial interface has to run …

If I remember right that is correct they dont feed the rx/tx through the debugger/stlink, even if you connect the solder bridges. The PA9 PA10 (if I remember right) are available as pins around the s …
