There is a difference between the manual and CubeMX settings for LCD_VLCD

R.K
Associate II

The Additional Function of PB2 is LCD_VLCD2 in the data sheet, but the same pin is set to VLCD1 in dm00171429-evaluation-board-with-stm32l073vz and CubeMX.

Which is correct?

I will attach the corresponding image

Hello,

The datasheet is correct.

Regarding the reference manual, table "VLCD rail connections to GPIO pins" is wrong.

The error will be corrected in the next release.

Thanks again,

Imen

Hello Imen GH (ST Employee), @Khouloud ZEMMELI (ST Employee)

Thnak you for answer my question.

Well then, Is generated code by CubeMX Wrong?

I want to use LCD Bias Selector with 1/3 Bias.

Please tell me how to fix it.​ (using the HAL library)

The Reference Manuals also look different.

I do not know whether it is sufficient that for any port in the correct setting.0693W000008waSJQAY.jpg
