Blynk Library version: 0.6.1
I have a ePaper screen that I want to use a meal planner. I have the 7 days of the week and the meals are 7 text boxes that Blynk will send to the ESP32 and display them on the epaper screen.
At the moment every time you finish a text box it calls a function and updates the screen.
BLYNK_WRITE(V1) // Monday textbox is on V1 for example
int monText = param.asStr(); // assigning incoming value from pin V1 to a variable
BLYNK_WRITE(V2) // Monday textbox is on V2 for example
int tueText = param.asStr(); // assigning incoming value from pin V1 to a variable
This works, but is kind of annoying when you have to update 7 things at once.
I am searching for a way to pull all text boxes when you press a virtual button on a vpin. I cannot find anything via Googling or searching on this forum.
Any help would be appreciated or if you have a suggestion on a better way to do it, that would be great also.
