In a project i will use a GLCD with ST7920 Cobtroller in SPI (serial) mode not in parallel. I tried som items listed with SPI but the y will not work. Is there a chance to get the GLCD ST7920 hardware macro with SPI mode, or can anyone give me a hint to bring it to work. The project uses an Arduino ...

Hi Martin, let me think over :roll: The speed of a band-saw is about 800m / min as upper limit. 2040mm length of the band and a diameter of round about 350mm for the roller guides gives roundabout 800 U / min for the roller guide. This will be ~13Hz from the inductive sensor. Not so much. The lower ...

The facts: Using pic 16F887 LCD 16x2 characters an inductive sensor and a bit of peripherie i tried more than 5 ways to get a stable output of the rpm of the guide roller but...
