Re: ECIO40P16 ( 33EP256MU806) compilation errors and latency
Thank you again for your suggestions. I will try my best, however, I am limited with the measurement hardware... As promised I did attach the Flowcode 9 logic which works: ECIO40P16 communicates with the "uOLED-128G2" display (Comm speed 9600 baud, F0 set as Tx, F1 set as Rx and D0 set as RESET). Pl...

Re: ECIO40P16 ( 33EP256MU806) compilation errors and latency
Thanks again for you suggestions. I think I found the issue... I did add 5 sec delay after the memory card initialization and lowered the speed to 19200 baud. Then added 50 mS delay after the next 3 commands to clear the screen, set background and foreground colors. Now I have the responce on Rx pin...

Re: ECIO40P16 ( 33EP256MU806) compilation errors and latency
Thanks again for you help!
I was looking with the scope on Rx pin.
No responce, just noise.
The baud rate is correct.
On Arduino on Rx pin has a trail of responces all the time.
Is someting wrong with the F0 and F1 port?
I did try G6 and G8 - no luck...

Re: ECIO40P16 ( 33EP256MU806) compilation errors and latency
Thank you for the hints.
Very much appreciated.
I will analyze the responce. Hopefully it will be informative.
Also, I thought to slow down the communication speed to see the impact.

Hello everyone, I am trying to connect using the ECIO40P16 controller to the 4Dsystem 1.7' uOLED-160G2 OLED display. So far, I can display only a little circle. All other print commands are ignored. If anyone could provide an example of the working communication in hardware (in simulation mine works...

Re: ECIO40P16 ( 33EP256MU806) compilation errors and latency
Hello all, An update. I added a 2 sec delay between all initialization commands, and now the screen clears and prints only the first command, the "degree circle". I did check the display data sheet and a responce from the OLED is required before sending the next command. However, in the Flowcode dis...

Re: ECIO40P16 ( 33EP256MU806) compilation errors and latency

ECIO40P16 ( 33EP256MU806) compilation errors and latency
Hello all, After I added the OLED display component (uOLED-128G2, 4D Systems) to my project (ECIO40P16, Controller: 33EP256MU806 ), the inputs scanning became very slow. The attached keypad is not reacting every time the key is pressed. Also, after adding the display, the following compilation warni...

Hello all, Could you please provide more information on the XY plotter? I do have a small 3 axis CNC machine and I would like to drive it from a controller programmed with Flowcode. I did find the old "XY plotter.fcfx" V6 program but it generates errors in Flowcode 8. Also, I do not see any hardware...

Re: Draw a circle using 2 stepper motors
Thank you for the link, Martin. I did check the Bresenham algorithms, they do look promising. They are great for drawing on the displays but, there are some other issues when it comes to the mechanical implementation: acceleration/deceleration, linear speed when following a curve etc. I did also not...

Re: 4Dsystem 1.7' uOLED-160G2 OLED communication issue
hello Benj,
forgot to mention:
changing the size of lettets and numbers does not work. the fonts will stay at initial "0" size, regardless of the entered parameter.
Thank you again.
