Good morning I have a small lathe I would like to control Via Arduino board, A4988 driver and NEMA17 engines Since I have to do simple work (go back one piece or lower it) I thought as a display to use a nextion model nx4832t035_011 From this I would set the turning values and the percentage As well...

I make a premise when using UART0 RX works fine I wanted to use UART1 RX to not have to continue to pull the interface that connects to UART0 port that is clearly used by the programmer, I understand that the problem is not resolved continue to connect and disconnect the interface Thanks for the hel...

I tried with UART channel 2 channel 3 and channel 4

(I read this post at home at the weekend, so the read flag got set

I wish to thank you for your concern

I notice the problem nobody cares even a simple response from the employees could give pleasure

Are you testing on Real hardware or in the simulator not sure but I think interrupts is not supported in simulation

I am interested in this question as well

No I'm performing the tests directly on the hardware simulation of interrupts know that does not work

Goodmorning everyone
I ran several tests, but I can not use UART1 Interrupt with Arduino Mega2560 I tried with every door hardware without any success

Good day to all
Someone could help me to adapt the code for Arduino UNO or NANO or MEGA Thanks

if you verify well the second string exceeds 16 characters display
this type of error to different behavior unpredictable, it is still the error of string too long

I wanted to ask if you can support
for this new NFC RFID module http://www.elechouse.com/elechouse/inde ... ts_id=2205
  with NFC support already integrated in smartphones
thanks x the help Happy New Year

I wanted to know if anyone has had experience
with LCD i2c I noticed that exists as a component but there is no explanation.
It can be used with PCF8574?
In the properties LCD address using the PCF8574 with pins 1,2,3 at high level
what value should I set?
Thanks for the help

Hello Benj

Honestly I noticed this consideration by reading the manual of avrdude , but it was the only way of experiencing different arduino with a positive result , normally look to the result if it works for me is ok

still problems with the programming of Arduino Mega 2560 I state that it is a version of the original Arduino I noticed that in recent versions you can not manipulate compiler options Programmer this is what I get by programming Launching the linker/assembler...

Hello John
to find a solution to the problem
I too have the same problem

thanks benj
I was just missing out on a glass of water
I forgot to bring to earth the R / W pin of the LCD
I apologize

I'm probably missing out on a glass of water
I can not run with 20x4 LCD Arduino Mega2560 44780
I tried it as an example: lcd printing message in the examples V6
I state that in the tests using the protocol 4bit
I tried with the PORT_A PORT_B
Nothing to do anybody can help me Thanks
