HSEROUT on an 08M2

A quickie question on hserout.

Noting this statement in Manual 2 -

The hserout command is used to transmit serial data from the fixed hardware
serial output pin of the microcontroller. It cannot be used with the serial
download output pin - use the sertxd command in this case.


With - hsersetup B9600_4, %00
How then do I get hserout true data at 9600 baud to work on an 08M2+ ?
Will sertxd output true data at 9600 ?, because it didn't seem to when I tried.

Neil.

Hi,

AFAIK that's an error in the Manual (when applied to the 08M2). HSEROUT can be used with Leg 7 on an 08M2 (or Leg 3 with a suitable POKESFR to the Alternate Pin Function CONtrol register).

Cheers, Alan.

Yes; a typo - most likely a copy-paste-edit oversight in copying text from the SEROUT to the HSEROUT command description.

The HSEROUT command works on whichever pin is used for its output when the command is supported.

Bits in the mode byte are used to select true or inverted serial. Your mode byte is correct for true serial.

Sertxd uses a fixed baud rate and polarity (inverted). You can use serout instead on any PICAXE where the Serial Out pin has a port.pin number.
