U8G2_ST7567_ENH_DG128064I_1_HW_I2C

[mvromancini]

Hello, I've been using the U8G2 for some time and I haven't had any problems with the constructions of the SSD 1106 and even 1309 128x64 I2C display line. but I'm having difficulties with the display U8G2_ST7567_ENH_DG128064I_1_HW_I2C u8g2(U8G2_R2,U8X8_PIN_NONE); it doesn't work in 1_WH_I2C mode only in SW_I2C could you help me. OBS I use the entire SSD I2C display line without problems with the U8G2.H in HW mode. but for reasons of size and cost I am having to use another display in the case of the GM12864-59N VER 2.0 IIC and I am not getting success in working it in my project in HW_i2C mode.

If there is no wiring issue, you could lower the bus frequency: https://github.com/olikraus/u8g2/wiki/u8g2reference#setbusclock

u8x8->i2c_address = 0x07e; / issue 1159, use different i2c address /
break;

The line with the I2C address

Thank you, friend, for giving me the attention to answer all my questions. and I consider the problem solved and here is the correction tip for the constructors of the St7567 line in I2C that do not work in HW_i2C!

No problem, note that there 8s also a high level function to change the i2c address.

Yes, after picking it up and analyzing it, it was clear that you have it and it was worth getting to know your project in more depth, which is very good,,,keep it up always!!!!
