TinyDuino Processors & TinyShields / Re: TinyScreen+ and GPS module
« on: April 04, 2018, 04:13:46 PM »
Dear Ben,
Sorry to reopen an old topic but still am struggling with this old problem (and SoftwareSerialZero library).
Indeed the transmit from GPS to Tinyscreen is indeed OK (i.e. the A1 pin works well) but the transmit to the GPS seems not to work (i.e. A0 pin). i.e. I'm sending $PSRF103 commands to the GPS that doesn't work with Tinyscreen+ although the same command is working when I'am using another setup with tinyprocessor board (328P).
Have you tested the Rx/Tx both ways ?
I noticed that in SAM21D datasheet that A0 and A1 pins are different (Analog for A0 and PWM for A1) - could that be pqrt of the explanation ?
I'm quite blocked now - any help you can provide ?
Thks
