Smart solder reflow oven exterior

Kilohercas

2 days work on exterior and today i can say, it turns out better than i expected . Now only UI programming is left, RTC, PID,PWM are working and i can do reflow soldering even today, but i need to make clean UI.

Still don't know how can this project be completely ignored by in this contest, but where is other contest on STM32F429 that needs to explore DMA2D peripheral and what is exactly what i need for my user interface, alpha blending for 2 temperature graphics, also transparency for on screen keyboard and so on.( but i am running low on SRAM, so it could be a challenge )

  • Hi Linus,

     

    Good looking build.

    You should be able to make a nice usable UI with the tools you have.

    intel inside, idiot outside , so no, it will take lot of time to do that. and i am not good at programming

    Hi Linus,

     

    Think about using sprites.  They are very low on memory use and you can set them up with counters to paint them at the right location on the screen.

    Good resolution displays are both a blessing and a curse.  I used an 8085 to drive a 400 by 400 pixel display back in the early 1980's.  We used a memory board with one bit display resolution for each pixel and then just dumped the array to the display.  Crude but it worked for real time updates.

    i don't know how to do gradient fillings , and also color mapping by only using c code. It would be easy to make it look like window 98, but i am going for windows 8 look if you know what i mean

    right now i have concerns about:
    making temperature graph that looks good, and still is informative, not just plain line, but something more, like blend two graphs from T1 and T2 with color map by suing alpha blending.

    Second how to write keyboard application that can return data in right format, and jump between windows (text box). I am also have problems with double interrupts, like how to understand that i pressed button only one time, and not 20.

     

    Third, graphical layout of all settings, check boxes, and so on.

    Hi Linus,

     

    Have you used the de-bounce capability of the PSOC?

    Its a quick way to isolate a single touch and ignore multiple detection interrupts.

    I am not sure which display functions are supported by the PSOC.  I used to do brute force pixel drawing for my project many years ago.  Hopefully you have better software tools to do this than I did.

     

    Unless you have a good visual graphic support, you can always do a paper layout and count pixels for your layout.

    I am hoping you have access to some drawing tools to simplify the task.

    i have problems with STM32, not PSoC5LP, since PSoC5Lp programming is nothing compared to STM32F429...

  • in reply to Kilohercas

    I have no experience with the STM32, so I cannot help you there.

    Have you contacted the folks there?  It was my understanding that they had some nice graphing support tools available.

     

    Keep trying, you are learning a lot.
