Hi all,
I have the same Raystar like Jbdriver.
On a LPC17 Core with 5V and 3.3V it is working like a charm.
But on the STM32F4 (MB997D) it is not working, same issues like jarvis:
What I have tested yet:
* External power supply with 5V (Pin J2) and 3.3V (J15_S middle Pin) is not working.
* Also with the 3.3V regulator from LPC17 Core it not working.
- STM32F4:J2 -> LPC17:J2
- LPC17:J15_S Pin 3v3 -> STM32F4:J15_S middle Pin
- STM32F4 USB and LPC17 power supply
The left display is also not working 100% correctly. Some characters are wrong
In my opinion it is a timing problem with the enable pins.
Where can I set the "LCD type to 0x02"? In MIOS terminal this option is missing for STM32F4.
Best Regards
Jack
