### TerSer Installation
Go to library manager in your Arduino IDE and search for 'TerSer'.
Alternatively just download the TerSer.h into your sketch folder and include it with:

UBRR0= 103; // 9600 bits/s

If you need another baud rate than 9600 you can adjust the value in the TerSer.h according to the table below:
| Baud rate | UBRR0 register *(@16MHz clock)* |
| Baud rate | UBRR0 register *(16MHz clock)* |
| ---------- | ---------- |
| 2400 | `UBRR0= 416;` |
| 4800 | `UBRR0= 207;` |

### Function reference
| TerSer function | |
| --------------- | --------------- |
| Car(cc); | Send code cc to the UART |
| cc=Get(); | Wait for a key depressed. Use Teraterm, too tricky with Arduino Terminal |
| Text("abcd"); | Send the text and add a space |
| Textln("abcd"); | Same with CRLF |
| CR(); | Send a CR-LF |
| Bin8(v); | Display the 8 low bits of the variable v, converted to integers (all add a space) |
| Bin16(v); | Display the 16 bits of the variable v, with a dot in the middle |
| Hex8(v); | Display the 2 nibbles of the variable v, converted to integers |
| Hex16(v); | Display the 4 nibbles of the variable v, converted to integers |
| Hex32(v); | Display the 8 nibbles of the variable v, converted to integers |
| Dec8(v); | Display the variable v, with its signs if signed and non-significative space or zeros |
| Dec16(v); | Display the variable v, with its signs if signed and non-significative space or zeros |
| Dec8u(unsigned); Dec8s(signed); | Shorter code |
| Dec16u(unsigned); Dec16s(signed); | Shorter code |
| Normal(); | ..+nnn default mode (a dot represents a space) |
| Spaces(); | +..nnn best for tabular data |
| Zeros(); | +00nnn if you prefer |
| Compact(); | +nnn same as Arduino, but a + is shown if positive signed variable |
