LCD ST7920 does not work correctly on 1.3

[HIMjack666]

worked well on the version 0.9, but on 1.3 like this:

PS: sys.lcd("73")

[emax73]

SPI Clock for this controller is 1.25 MHz,
Now frequency 10 MHz,
maybe try
dev_config.clock_speed_hz = u8x8->display_info->sck_clock_hz;
at u8g2_esp32_hal.c line73 ?

emax73, thank you a lot. Working good on 1 MHz.

Hi, i have the same problem with ST7920, i am on the latest version 2.1. For me this is a new install set-up.
I also use a VS1053 for encoding the data. When i choose DAC for example, the display is working fine. So there is a problem witch the combination of ST7920 and the VS1053.

Hi! The same problem with combination of ST7920 and the VS1053. How to use different SPI interfaces on LCD and VS1053 decoder? I think slow LCD exchange interrups by decoder

HI, my problem was solved bij adding a diode in the data line.
