Asynchron serial interface (UART)
For this functionality the IO project (base or pro) has to be uploaded to Netzer.
In UART mode signal RX is configured as receive pin and TX is configured as transmit pin for serial interface.
The interface can be configured via Netzer web interface.
Baudrate
The following baudrates are supported. Due to external crystal and clock generation a system error arises.
| Baudrate in Baud | Error in % |
|---|---|
| 300 | 0 |
| 1200 | 0,01 |
| 2400 | 0,01 |
| 4800 | 0,0072 |
| 9600 | 0,01 |
| 19200 | -0,08 |
| 38400 | 0,098 |
| 57600 | -0,08 |
| 115200 | 0,47 |
Data format
The standard data format is one start bit, 8 data bits and one stopbit. The parity bit is optional and can be set like (only IO_pro):
| Mode | Description |
|---|---|
| None | No parity is transmitted/accepted. |
| Odd | An odd parity is transmitted/accepted. |
| Even | An even parity is transmitted/accepted. |
| Mark | The parity bit is always 1. This setting can be used to emulate a second stop bit. |
| Space | The parity bit is always 0. |
Handshakes (only **IO_pro**)
