I did a program, running well, for Arduino Pro Mini ATMega328P 3.3V 8MHz in Arduino IDE with Wisol SigFox BRKWS01 modem and Holtec voltage regulator HT7533-1 (AREF 3.3V, VCC@328P and VCC@BRKWS01).
Now I would like to reprogram it for ATtiny202 by using MPLAB X IDE and MPLAB Snap (Part Number: PG164100). Unfortunately I am beginner to MPLAB X IDE and I was unable to reproduce examples "gettin" Getting STARTed AVR Events for ATtiny817 Xplained Mini board with ATtiny202-SSNR (CS8 Compiler) on start.atmel.com
Which pins to use at ATtiny202: USART Pin 2, PA76 (TXT), Pin 3, PA7 (RXD); Pin 6, PA0 (Analog input for voltage measurement) and Pin 5, PA1 (digital output to wake up Wisol modem). Hardware USART communication.
Remark: Rename extension of attached file from TXT to INO
