parallel processing using ili9488 display and microcontroller

[Sharan]

i have created a user interface using touchgfx when i go to the second page sine wave has to be generated and parallelly display has to work is it possible to do this using controller or should i go for mpu

[Sharan]

yes

I am not sure how to help you as I don't know what you want to do exactly, also it doesn't seems to be related to TouchGFX.

But I found some videos that could help you:

1. ST guide on how to generate sin wave 
2. Controller's tech's guide on how to generate sin wave and see it on ili screen

Hello @Sharan ,

Were you able to move forward on your issue?

hi                                                                                                                                                                                          i am working on stm32mp157d-dk1 now so now i will be generating sine wave using the mpu instead of microcontroller and can we access the adc and dac using arm cortex a7 and if possible how to do it?

Hello @Sharan ,

There are many ways to generate a sin wave.

You could loop through a lookup table to periodically update the value of your DAC.

You could use the math.h library to use a sin wave in TouchGFX.

Etc.

If you have another question related to TouchGFX, don't hesitate to ask it! :smiling_face_with_smiling_eyes:
