Important Notes

• For optimal wireless performance, make sure that there is no metal near or under the antenna. You can improve the bandwidth by adding grounded metal to the sides of the antenna.
• The same pin on the RP2040 is shared by IRQ and CYW43439 DIN/DOUT. This means that IRQs can be checked when there is no SPI transaction in progress.
• Some wireless interface pins are shred because of the pin limitations. VSYS monitor and CLK are shared and this is why the ADC can read VSYS only where not SPI transaction is in progress.
