BASCOM-ARDUINO : Adruino Resetting with incomming serial data : NEWTOPIC
Hi all
I've got a Arduino mega project hooked up to a PC for sensor data logging. The comms is USB to the micro USB port on the arduino. I have got MS Access to send an sensor ID via the usb comms. The Arduino reads this ID and reads the sensor and transmits the data back. Works well
I have noticed something weird. When the ID request is transmitted to the Arduino for the first time only ,the Arduino resets. Then it runs up fully. This is not a big issue I'm just wondering why and should it.
Here is the code snippet that reads the comms
[code:1:1a5ecbf803]
Serial_flag = Ischarwaiting() 'Listen to the Uart rs232 port for data to turn up
If Serial_flag = 1 Then 'We got something in the Uart
Rx_data = 0
Rx_data = Waitkey() 'Get it
Filter_command 'Call the sub that fiilters the ID and reads the sensor
Locate 1 , 1
Lcd Space(16)
Locate 1 , 1
Lcd Rx_data ; ": " ; Sensor_value ' Display it on the LCD before it is sent out. Used for data checking
Print Sensor_value 'Send the data back to access
Tx_data = 0
End If
[/code:1:1a5ecbf803]
The whole project works well but just trips up for a few cycles at the start
Thoughts??
Cheers Snow

no idea . But it does the same when I use the terminal emulator from the IDE : It does a reset when it is called

BASCOM-AVR : Xmega: What are Config DMA and Config ADC are doing? : REPLY
Ok, then have it your way :D
To point out the initial question, which you thought helpful for others and which may give some meat to the thread for readers looking it up, here's the equivalent for this config:
[code:1:647febaa8b] Config Dmach0 = Enabled , Burstlen = 2 , Chanrpt = Disabled , Tci = Lo , Eil = Lo , Singleshot = Disabled , _
Sar = Burst , Sam = Inc , Dar = Block , Dam = Inc , Trigger = &H10 , Btc = 4000 , Repeat = 1 , Sadr = Varptr(adca_ch0_res) , Dadr = Varptr(samples(1))
[/code:1:647febaa8b]
Notice I have changed Dar, not having to reload it via code.
---->
[code:1:647febaa8b]' Bitnames
Const ERRINTLVL_1 = 3
Const ERRINTLVL_0 = 2
Const TRNINTLVL_1 = 1
Const TRNINTLVL_0 = 0
Const SRCRELOAD_1 = 7
Const SRCRELOAD_0 = 6
Const SRCDIR_1 = 5
Const SRCDIR_0 = 4
Const DESTRELOAD_1 = 3
Const DESTRELOAD_0 = 2
Const DESTDIR_1 = 1
Const DESTDIR_0 = 0
Const DMA_CHEN = 7
Const DMA_CHRST = 6
Const DMA_REPEAT = 5
Const DMA_TRFREQ = 4
Const DMA_SINGLE = 2
Const DMA_BURSTLEN_1 = 1
Const DMA_BURSTLEN_0 = 0
DMA_CH0_TRFCNT = 4000
DMA_CH0_REPCNT = 1
DMA_CH0_SRCADDR = Varptr(adca_ch0_res)
DMA_CH0_DESTADDR = Varptr(samples(1))
DMA_CH0_CTRLB = Bits(ERRINTLVL_0 , TRNINTLVL_0)
DMA_CH0_ADDRCTRL = Bits(SRCRELOAD_1 , SRCDIR_0 , DESTRELOAD_0 , DESTDIR_0)
DMA_CH0_TRIGSRC = &H10
DMA_CH0_CTRLA = Bits(DMA_CHEN , DMA_BURSTLEN_0)[/code:1:647febaa8b]
But - if you write it this way, you gain nothing, code and runtime is equal to the config line.
This may change a bit, if after initial config (as above) only necessary registers are written for a restart, which would look like:
[code:1:647febaa8b] DMA_CH0_TRFCNT = 4000
DMA_CH0_CTRLA = Bits(DMA_CHEN , DMA_BURSTLEN_0)[/code:1:647febaa8b]
As far I understand the documentation TRFCNT will be only automatically reloaded in continuous mode, so for a single run it has to be reloaded via code.
After that, re-enabling the channel should do the trick.
Try it out and report it here.
Again, as already stated: You gain a few cycles, which you are wasting by thousands in wait-cycles, but it still may be interesting from the academic POV.

Hi Kimmi,
I find that topic for PLL using a TSA5511 with Atmega8, but there are incomplete.
I founded this schematic 2 day ago by browsing over the internet, but they are using a PIC.

BASCOM-AVR Old versions : line input command : NEWTOPIC
Hello,
working on reading txt-files on m328. I think tabs are the marker, to end one input and start another, right? So, what can I do, if the read in block is bigger then a string can contain? Is there a way, to set a pointer on my own, for example a point?
Thanks
Christian

BASCOM-AVR : overall undervoltage lockout for microcontroller and pheripe : NEWTOPIC
Hi
I use a 12volt battery to bakup an industrial circuit.when main power disconnected i should send a condition status to a plc via rs232.
my main problem is buttery undervoltage. if battery be full charge every thing is ok. but when battery start to reduction voltage by time, the problem start.
9volt requlator used for pheriperal circuit start to unrequlate voltage.
i need a under voltage lockout circuit for 12 vlot. it should start the circuit with 11 volt and stop circuit with 10 volt.
any idea would help me.
thanks.

[img:aafebdf2ac]http://members.home.nl/hobbycorner/images/weatherstation/weatherstation1.JPG[/img:aafebdf2ac]
32 degrees Celsius today at Tilburg / Netherlands. Here is the proof :D
The information is fetched bij a Nodemcu and weatherinformation is send to the serialin1 port of a Arduino Mega 2560 with an ILI9327-display.
[b:aafebdf2ac]Nodemcu:[/b:aafebdf2ac]
Were can you find the code for the nodemcu weatherstation
[url]https://github.com/squix78/esp8266-projects/tree/master/arduino-ide/weather-station-v2[/url]
We ripped the OLED-code from the Nodemcu software. Just used the info that comes from the serial port at 115200 baud
[b:aafebdf2ac]Brief: [/b:aafebdf2ac]there is a plug-in for the recent Arduino-IDE (version 1.6.4) that can be used to program the Nodemcu
You can use Generic ESP8266 modues, Nodemcu and Olimex MOD-WIFI-8266
At the preferences you can add this link and use the board manager to add the NodeMCU and ESP8266 boards.

[b:aafebdf2ac]Weatherinfo:[/b:aafebdf2ac]
API-key you can get it at
www.forecast.io
at the bottom
Forecast API
1000 calls are allowed for free. In the Nodemcu software every 10 minutes a call is made to get new weaterinfo.
Thats is 6 times an hour, 6 x 24 = 144 times in 24 hour.
Do a test, just the nodemcu. If everything is alright you will get this information from the Nodemcu

In the ZIP-file the main program, two include files and files for optional AVR-DOS.
The hardware is from CE - Chinese Electronics. It is an Arduino Mega 2560 with an ILI9327 display. 400 x 240 pixels.
Also in the zip-file BGC-icons and the source of these icons (BMP).
Here a picture of the complete hardware:
