| + | ====== Asynchron serial interface (UART) ====== | ||
| + | <note important>For this functionality the **[[io_project|IO project]]** (base or pro) has to be [[fwupdates|uploaded]] to Netzer.</note> | ||
| + | |||
| + | 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**) ===== | ||
