trmt (text_interface, any_data [, any_data, …] );
Transmit data to the specified interface.
The interfaces is specified in text form – “UART1”, “SPI2”, etc.
Specifically for the I2C case, the interface also includes an optional action, immediately following the interface identifier.
Actions can be
“:S” - The transmission is preceded by an I2C start condition.
“:P” - The transmission is followed by an I2C stop condition.
“:R” - The transmission is preceded by an I2C repeated start condition.
Data elements can be one or more of integer, real, or text type. Integer information sends a single data word, real is transmitted in its native form (8 bytes), and text is transmitted as a zero-terminated string of bytes.
trmt “UART2”, 10, 20, 30, 40; ‘ send bytes 10, 20, 30, 40, to UART2
trmt “SPI1”, str1; ‘ str1 is a text variable transmitted over SPI1
“IIC1:S”, 0x44; ‘ a start condition
followed by byte 0x44 is
‘ transmitted over I2C. The bus remains open for
‘ following bytes
“IIC1:P”, 0x80, 0xfe; ‘ a stop condition is
generated after sending the
‘ supplied sequence of bytes
