WebFeb 27, 2015 · When we want to read the data, you can read from eusart_rx_buffer_rd until eusart_rx_buffer_wr. Of course, when more than 2048 bytes are stored at the same time, the buffer will be overwritten and you'll lose data. There are some tricks you can use to work around that though. You can change EUSART_BUFFER_SIZE to suit your needs. WebMay 4, 2016 · The RX buffer will be checked for incoming data next by reading the variable 'eusartRxCount' which is a global variable defined in the auto-generated eusart code. This variable is incremented anytime the RX interrupt occurs. Simply check this value for non-zero to see if any data has been received.
