For reading data, dataAvailable
signal will be emitted after successful read.
buffer | Buffer to store received bytes in. |
bufferSize | Size of receive buffer. |
Implemented in semf::CanHardware, semf::I2cMasterHardware, semf::I2cSlaveHardware, semf::SpiMasterHardware, semf::SpiSlaveHardware, and semf::UartHardware.

pure virtual |
Stops the read process as fast as possible without destroying anything. The readStopped
Signal gets emitted if the call was successful.
Implemented in semf::SoftI2cMaster, semf::SpiMasterHardware, semf::SpiSlaveHardware, semf::Stm32Can, semf::Stm32I2cMaster, semf::Stm32I2cSlave, and semf::Stm32Uart.

Signal semf::app::Communication::dataAvailable |
Signal is emitted after size of data from called read()
function are received.
Definition at line 58 of file communication.h.
Signal semf::app::Communication::dataWritten |
Signal is emitted after data from called write()
function are written.
Definition at line 56 of file communication.h.
Signal is emitted if any error happens in the communication hardware or hardware abstraction layer.
