PIC16F88 10 OLED Display

Site for Eduqas/WJEC - Go to the AQA site.

Using the Winstar WEH001602E - I broke my OLED module. Temporarily abandoned.

The wiring diagram is probably OK. The display showed "Hello world" along with a lot of other unwanted characters. It might be a software problem.

Data sheet from Picaxe.com - If you buy this from Picaxe, use the display without the serial three wire interface.

Interfacing PIC16F88 Winstar EH001602E

If the RS pin is LOW, transferred data will be treated a command.
If the RS pin is high, the transferred data will be treated a text character.
To transfer data, Enable must change from high to low.
It's easy for the MCU to run too fast for the OLED module.
- Commands or data should not be sent until the busy flag is clear - Recommended.
- Or use conservatively specified delays and hope for the best - Easier but it might not work 100% reliably.
- This example uses the second, less safe approach.
