https://www.sparkfun.com/datasheets/Components/General/COM-09622-MAX7219-MAX7221.pdf Page 8 tells you register that controls dotpoint. Page 7 has register address mapping. :) When trying to interface with this, i recommend using display test register to test that you can get all segments and dotpoin...

I personally use this:

Hi Matt! For your second and third question about the purpose of push buttons/leds, take a look at the datasheet; http://ww1.microchip.com/downloads/en/DeviceDoc/21801d.pdf mcp2515.PNG So it means in general that theyre configurable. But mostly i think the flowcode component just uses them as extra ...

Hi! After couple of tries, i think theres something wrong with the RPI tcp/ip component or modbus tcp component. Whenever i try to establish connection between modbus master and rpi, the rpi seems to not pick up... Not near my pc at the moment, so cannot attach example program.. Just take modbus tcp...

Do you have time to check out the reset pin voltage with scope when doing programming cycle? If I remember correctly, this pin may have high voltages (9-13v) present when doing high voltage programming..

That sounds a bit like a hardware problem to me, if chips are dying after couple reprogramming's... How old is the HP programmer board? Have you tried different power supply for the HP6339? (Recommend this first, as ive seen some PSU's fail) EDIT: check this too https://www.matrixtsl.com/mmforums/vi...

Have you looked at the correct chip pack (ARD) for Arduino?

Can you go to the cmd and run following commands on there, to check that folder ownerships are ok? Should be something like NT-System on all of them, but it might change in different os versions. cd C:\outputfolder\ cd to folder you want to save the file first, im using outputfolder here. Then outpu...

Do you happen to have antivirus like BitDefender, F-Secure or ZoneAlarm? Can you try disabling it for a short time to test out ?

Theres typo on the screen, it is the Checkout button that you need to press.

Modbus TCP is now included in Flowcode 8, I've not managed to do a massive amount of testing but certainly the simulation is looking good. Hopefully I can test more embedded TCP/IP and WIFI modules soon to ensure these all work as they should. Nice to hear, i gotta give it try when i have time. Mig...

Are you using display scaling on the 1366x768?

Here are some things about it too: http://machinerysafety101.com/2009/03/06/emergency-stop-whats-so-confusing-about-that/ And if you ever wondered, by EU directive reset button is now required before machine can start again operating after emg stop was released. And i think US have their own require...

why is it fitted ? what is it doing ? is there any special characteristics required if i need to add one ? would a BAT85 be ok or is the volt drop too high? I think it is fitted there to prevent high voltage programming mode supplied reset signal (10-12.7V?) entering the +5v rail... Ive just used 1...

What have you allready tried? Could you post your flowchart?

In short, your program has pretty fine commenting inside, and you should be able pretty easily to start decoding what your program does. Just write it in pseudocode, draw it on paper, sand, snow, whatever you feel the best. Draw images and charts from program, what is this part trying to archieve? T...

Hi!
Today i had a project in my mind that would need nrf8001 or similar BLE radio... Would it be possible to create ready-to-run macros around these components maybe in future considering the IoT fuzz around?

Hi! It might be because of your low post count, it should clear after couple posts. What version of Flowcode are you running? 7.xx?

Hi and welcome to forums! Can you drop a pm to Leigh or Ben?

This book is still great even though youre using it with Flowcode V7!

Still on sale for 19,00$ on April 2018 !

The glcd and character displays are very different beasts and you need to work on your code a bit. Happily, flowcode 7 has easy macros to help you out and saves some icons in the way if youre using gLCD. But you just need to start moving in your code through, and coding the glcd manually to same way...

I personally have used this STN1110 chip to communicate, as im not the fan of re-inventing wheel... :D But you should be able to do same things over e-blocks CAN, but might need to invest into the SAE documents about the bus.. Here are some quick links i've saved and which seem still operational: ht...

Hi and welcome to forums. The AT+CUSD will work only if SIM supports it. Firstly, if you put your SIM card into phone and there is new option in menu that has SIM card logo or similar, this is the menu you want to get to using the AT+CUSD commands. If the menu is not availabe, AT+CUSD is most likely...

I personally use paint.net to do that! GIMP or similar might be good too.

Using looped back serial port and slave simulator, i got traffic correctly, but simulations hangs on this after slave sends reply... But data looks correct. I dont have any hardware at the hand for this moment to test this on. :cry: mbtest.PNG Request: 01 01 0000 0004 3DC9 01 - Slave 01 - Function 0...
