oops… forgot to flash to new firmware … i’ll be back

flashed the firmware

and … it works !

lesson learned, sometimes the connection (UF2 method) breaks So make sure you have a connection with the device

I just followed this example code Reading Coronavirus COVID-19 Live Data using Wio Terminal

after updating the wifi core

easy connecting to a breadboard with RPI expansion board

That’s a nice way.

Hi @BoRRoZ

You adapter board means you can follow this Audio wiki also! https://wiki.seeedstudio.com/Wio-Terminal-Audio-Overview/

trying to interface a plantower pms5003 on a new sercom uart to create a mobile air quality device.

but I’m new to sercom and its complicated
I found this code snip (not tested yet) … it should create an uart but you can’t use I2C at the same time … is that possible I2C + UART on the grove connectors at the same time?

sercom left grove uart snippet

static Uart SerialPMS(&sercom3, PIN_WIRE_SCL, PIN_WIRE_SDA, SERCOM_RX_PAD_1, UART_TX_PAD_0);

void SERCOM3_0_Handler()
{
  SerialPMS.IrqHandler();
}

void SERCOM3_1_Handler()
{
  SerialPMS.IrqHandler();
}

void SERCOM3_2_Handler()
{
  SerialPMS.IrqHandler();
}

void SERCOM3_3_Handler()
{
  SerialPMS.IrqHandler();
}

And what is the max current ? on the grove connectors 3v3 line if you connect devices/sensors, I couldn’t find that info

Changed the power unit to LiFePO4 6000 mA followed by a DC/DC step up 3.2v to 5 v and a charger module So I can charge the device with my phone adapter.
The PMS5003 needs 5v but data lines are 3v3 so no need for level shifter when connecting to the WIO terminal.
