Serial port issue

Hi, I'm trying to use the HardwareSerial library for UART comms. I get an error within the void loop() that says that 'Serial1 was not declared in this scope'. Also will I be able to use the standard arduino serial library functions with this serial port after it is configured? (such as Serial1.read...

Re: UART interrupt to trigger buffer read on character pattern detection

See reply on my most recent query - viewtopic.php?f=2&t=2534 I don't think it's actually implementable live time at the moment, you have to incorporate another buffer

UART pattern detect interrupt

I have a stream of ASCII based NMEA sentences (each ending in 'LF') feeding into one UART and I would like to split them up and print them out to another UART. I am using the uart_enable_pattern_det() function to try and achieve this. My program is detecting all the 'LF' characters but upon detectio...

UART interrupt to trigger buffer read on character pattern detection

Hello! I have adapted the uart example code found here - https://github.com/espressif/esp-idf/blob/v2.0/examples/peripherals/uart/main/uart_test.c in the form shown below. I am looking to read the UART buffer in ONLY upon the recognition of the 'LF' (line feed) closing character than comes with ever...
