In the previous psl package, there were functions to control SQR1 and SQR2 pins individually. However, they are missing in the latest version and one has to use SQR4 function driving all 4 SQR pins.

With the latest firmware upgrades, it is made possible to generate sine and square waves simultaneously and we need to implement whatever the missing functions referring to the old python package.

Refer to following as a guide:

• SQR1
• SQR2
