In the data sheet and reference manual of STM32L073, LCD_VLCD1 is 42pin and LCD_VLCD2 is 37pin, but in STM32CubeMX, the instructions are reversed.Also, at 1/3 bias, the reference manual is supposed to use LCD_VLCD1 and LCD_VLCD2, but STM32CubeMX will...

I am using STM32L073.When using this ADC, the EOC of the flag ADC_ISR for which AD conversion has been completed does not change unless the EOCIE of ADC_IER is set.is it right.

Hi,In STM32L073, the ADC conversion time is stated as 0.875us with 12-bit resolution.Even in the actual test, it has been confirmed by the continuous operation of 1ch of ADC.However, I set the ADC results to be transferred by DMA, the ADC conversion ...

Is it possible to set the LCD drive voltage to 4.5VDC in STM32L073?When using a VA liquid crystal panel an LCD, it is said that it cannot be driven by 3.6VDC.

Thank you for your answer.I understand that for a 1/3 bias, I would use port of PB2 and PB12 or PE11.Thank you very much.

Thank you for your answer.In conclusion, which is correct, RM or MX?If the datasheet is correct, is it okay that MX is wrong?In addition, the table "VLCD rail connections to GPIO pins" of RM in English and RM in Japanese are also different, but this ...

I was thinking of monitoring ADC_ISR with software.However, I understood the condition.Thank you very much.

Yes.It was confirmed that the continuous operation of the actual test had an ADC total conversion time of 0.875us.However, with DMA, the ADC total conversion time doubles to about 1.8us.I wonder why.
