PlatformIO using wrong version of SerialHardware?

[JKain]

I'm writing (or, rather, copying from other people) some code for a Teensy 4.0/4.1, using PlatformIO.

Some known to be good code contains the following line:
ESCCMD_serial->clear( );

When I build it, I get the following error:
error: 'class HardwareSerial' has no member named 'clear'

I know the format is fine, since other similar lines, such as:
ESCCMD_serial->begin( ESCCMD_TLM_UART_SPEED );
compile just fine.

I did some Googling, and it turns out the Teensyduino version of Serial contains the 'clear' member (according to this page), while the Arduino version does not (according to this one).

So, it looks to me like PlatformIO is not using the correct (for me) version of HardwareSerial. Is it possible to get it to recognize that my Teensy needs a different version (yes, I selected the right board when I set up the project)?

Thanks.

The Teensy specific stuff now lives in the HardwareSerialIMXRT class, so try using that instead of regular HardwareSerial.

Thanks. So, do I just put that as an include at the beginning?

This is a known issue with 1.59. Using HardwareSerialIMXRT is indeed an effective workaround.

I appreciate the help, but I'm new here, and I can't figure out exactly how to do that. How do I do this?

OK, I figured it out. Posting here for anyone else who has a similar issue.

In the variable declarations, I replaced the line:
HardwareSerial* ESCCMD_serial[ESCCMD_NB_UART] = {
with:
HardwareSerialIMXRT* ESCCMD_serial[ESCCMD_NB_UART] = {

Turned out to be easy, but it was very difficult to Google this.
