Hi, I am working on an ATMEGA2560 with avr chipset. Overall goal I am trying to receive data from a device on ch1(inspectra), receive data from another device ch3(weather), and send clean info from both devices out via ch2(modbusSlave). I added a 2nd circular buffer so all weather data can be fed to...

I found this article on custom interrupts for AVR. https://www.flowcode.co.uk/wiki/index.php?title=Custom_Interrupts_-_AVR How can I customize this for channel 3? Enable code: UCSRB |= ((1 << RXCIE) | (1 << RXEN)); // enable USART receiver and receive interrupts Disable code: //UCSRB &= ~(1 << R...

Hi so if I understand correctly I should not do what I did below? I need to make an RXINT2 since FC does not have one made for me to use. Is there a way I can reverse engineer RXINT1 or RXINT0 so I can make an RXINT2?

Thank you!

Hi, I am programming an AVR ATMEGA2560 with AVR chipset. My program is supposed to poll two devices on (inspectra)ch1 and ch3(weather) via UART. There is a Modbus slave that is sending out the cleaned info on ModbusSlave ch2. I have been successful with inspectra and ModbusSlave working in tandem. I...

Thank you. I tried out the code. I was getting 0 in the 100 register. i used my LCD to diagnose the issue. I am getting back a string "00200E". See image below. I am supposed to get "H00200\r" I did try other strings and numbers all didn't have any issues. I can't figure out what...

Hi, I made a program that sends a command to a device, the device returns a string that is cleaned and put into a holding register. I am doing this to get three different strings. The issue I am having is that after I get the model number from the device the other items I get from the device (serial...

Hi,
A request I would like to make is a HEXTONUMBER() in the calculation f$ options.

Hello, I am playing with LCD I2C (Backpack) component. I was wondering how I to work the ScrollDisplay. I am unsure of what to input for the direction? I was looking at the wiki https://www.flowcode.co.uk/wiki/index.php?title=Component:_LCD_I2C_(Backpack)_(Alphanumeric) and it was not helpful. I wan...

Hi,
I was wondering is the circular buffer restricted to 8/16 bits? I have a fixed 99 byte string incoming that I am going to parse after receiving. I was wondering if I can use the circular buffer for these 99 bytes string?
