1 MHz interrupt is extremly frequent to handle it correctly and use the MCU to other tasks. You should use a PWM output or a dedicated oscillator circuit. Thanks for the reply. Yes, 1MHz will probably be a really high frequency. How to write a PWM program to be on P5 5KHz pin???? Can anyone show an...

I use licensed Flowcode6.
Is it possible to make a 1MHz interrupt at the B5 (it can also be some other way out) output with the Arduino Nano?
If so, how to do it?
Does anyone have an example of Flowcode timer code TMR0 or TMR1?

Thank you very much.

Hello, The ATMEGA328 used on the Nano does not have a period register and so it can only use the period overflow value 255. In later versions of Flowcode we generate a warning message to inform the user of the lack of hardware capability. Thanks for the reply. Is it possible to use timer 2 on Ardui...

I use an Arduino Nano. I put together a PWM test program (Look at the picture). On the PD6 pin I want a PWM 2kHz frequency. I measured the frequency with a Seale Logic Logic Analyzer. The frequency on the PD6 pin is 490.3Hz. PWM is not working properly. What am I doing wrong? How to adjust the 2kHz ...

Thank you very much. I'll try it.

EDIT- I tried it. I tried it and it works very well. Thank you, LeighM!

Hello, I'm using the display and Arduino Nano (http://www.ebay.com/itm/2-8-TFT-LCD-Display-Touch-Panel-SPI-Serial-240-320-ILI9341-5V-3-3V-STM32/201950756171?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649) The problem is that the slipped part of the displey is black.

LeighM thanks for the reply. I will try to set up and your proposal (Clock Polarity to "Idle HIgh" and Clock Phase to "Trailing Edge"). I have another question. How do you test SPI bus? You can paste the PrintScreen logic analyzer.? That to me would be helpful. And one more quest...

Here I checked SPI with "Seale logic" analyzer. SPI is not working.

Hello. I wrote a program Flowcode 6 for the AD9833 DDS generator . I use Arduino Nano. I helped you with this topic . AD9833 is controlled via the SPI bus. But I have a problem with the SPI bus. SPI is not working. I enclose a program Flowcode 6. The values of the bits for example 400Hz. Here is an ...

Hello,

I use Flowcode_6.
I too would need a component for GLCD display ST7920.
Datasheet is here.

Pretty please, if anyone has a component for ST7920.

Library for Arduino and ST7920 is here

Thank you.

Hello!

The victory. Thank you very much kersing .
I use a search and found.
Look at the picture.

I use the Arduino UNO and I2C glcd (SSD1306).
I wrote the test program "Hello World". It works fine.

Thanks again. I am very happy....... .

Thanks for the information.
Yes, yes, I used SSD1306 component. But this is not flowcode 6.?
Flowcode 7 has a SSD1306 component.


How to use Flowcode 6 and an I2C OLED display and component SSD1306?
I would need an example flowchart Flowcode 6. Does anyone dealt with this I2C OLED?

Thanks.

Hello,

On ebay I bought I2C OLED display,
Use license Flowcode 6.
How to write on the display "Hello World". Does anyone programmed such OLED display?
Please program (code of Flowcode) for writing on the OLED display.

Thanks.

Bravissssssimo, 7-segment 8 X works fine.
Thank you very much for example.
I am very happy to help .

STibor, thanks for the information.
I tried to Flowcode 6, but does not work. Absolutely nothing. What am I doing wrong?

I enclose a program Flowcode 6.


Stibor, nice project - https://www.youtube.com/watch?v=L_2jvbifOwk
How is this done? Arduino?

Thank you.

Continuing the theme. I use Arduino Nano and 8 X 7-seg. display with MAX7219. Connecting the Arduino Nano, and 8 X 7-seg. display the picture. I enclose a program written in Flowcode_6 I wonder why the program does not work? What am I doing wrong? Does anyone have a working program for the MAX7219 a...

I think it is a mistake to help in Flowcode custom interrupt. Code of help did not work

Here are the settings for the custom interrupt the Flowcode 6. Interrupt evry 1/100s.

Hello! Benj Thanks for the information. I managed to configure the 16-bit Timer1. I use the Arduino Uno and processor Atmega328p. Here are the settings Timer1 to interrupt each 1 / 100s for Arduino. The code works! // Arduino timer CTC interrupt example - interrupt evry 1/100s #include <avr/io.h> #i...

Hello,

Thank you Benj for your answer, but interrupt (ArdTimerDemo.fcfx ) is not not accurate.
I checked interrupt with the logic analyzer. See attachment below.

I need exactly interruption. It uses the 16-bit timer and the "C" code, but I do not know how?

I have a question.
I use an Arduino UNO and 16 MHz quartz.
I want to create a interruption at every hundredth of a second - interrupt 1/100s.
Which timer should i use? 8-bit timer or 16_bit timer?
How do I configure the timer register?

Thanks for the reply.

Hello,

Sean Danaher, very nice and interesting project.
In which language you programmed? Flowcode?
Unfortunately, I do not know how to program.

Greetings!

could you please write the algorithm of the program "DHT11v1.01.fcf" for the beginners.

Hello,

I agree. This would be good for beginners. My algorithm still does not work.
I would ask for an explanation DHT11.

Thank you very much.
