void setup() {

 *  The terminal process "platformio 'run'" terminated with exit code: 1. 
 *  Terminal will be reused by tasks, press any key to close it. 

I believe that the SPI pins are not defined, and I am not sure how to correct this.

Questions:

• do i need: 
  #include <M5GFX.h>
  #include <M5Unified.h>
  most examples only have:
  #include "M5Dial.h"

• wat to do with:
  ;platform_packages = tool-esptool.py@https://github.com/tasmota/esptool/releases/tag/v4.8.1.1/esptool-linux-amd64.zip
  ;platform_packages = tool-esptool.py@https://github.com/tasmota/esptool/releases/tag/v4.7.4/esptool.zip
  in my platformio.ini.
  I think they are not necessary because esptool.py is already mentioned in the build output, but it is not the latest version.

• And last but not least what to do with the spi pin error.
  If somebody can point me in the right direction, it would be greatly appreciated
  I know that as long I can get "hello world" to work, I'm going to have lots of fun with the M5Dail
