Hello, I am doing a project wich takes audio from an ESP32 via I2S, process it and then send bia i2S to an amplifier wich manage I2S signals as input.HARD:ESP32 (source of audio)ST nucleo F401Re (processing unit)Amp: MAX98357A.I manage to make work p...

Hello, i am dealing with an i2c issue.I am trying to trasnmit from my NucleoF401RE (as master) to an ESP32 (as slave). I cant make to ESP32 respond the device address. I take some measures off the SDA and SCL signalsI realized that SDA has cero hold ...

Hi, i am making a project with the ST NUCLEO F401Re using a TFT display of MCUFRIEND (not so good display), and the implementation is running with touchGFX 4.22.0.The display works with data serial using 8 pins of data and 4 to control (just for cont...

@TDK well, i give up and put the resistors ( the signal was good edges enough), and all start working. They went 6 hours of lost time ‌‌. So never trust in internal pull up. Thanks

Thanks for your comment @TDK , the edges get better but the problem is the same. I doble check the adress shift and its okey. You know if is posible to change hold time? i really think that is the problem.

@MM..1 The time of write8() is 78 clock cycles. In this case is about 0.976uS for each 8 bit write. Analysing the time per line update the measure was about 3,18mS.So in this case (380 pixels hight display) is 1,2 seconds, wich correspond to refresh ...

@Panchev68 well changing that time i gain some time in each transition. Anyway the laggi animation persists. Thanks for the advise.

As i responded to @AScha.3 , i did not checked the timming. I will do it in next days.I think a good option is to not update al the screen so i reduce the number of pixel i have to send. But i have no idea if it is posible to do with TouchGFX.Thanks ...
