Hello,

Trying to play catch up here but please can you send me your latest Master and Slave programs and I'll have a dig in and see if I can find out what's not working for you.

Hello,

What version of Flowcode are you using and can you attach your program for us to look at.

Hello Abhi, Looks like a nice board, as it's connecting to the network it probably should be ok. Have you had to load the firmware on yourself to allow it to be a slave to the MCU instead of hosting it's own firmware? The MQTT component supports 32 byte name, password and ID so this hopefully should...

In the MQTT Client component you maybe need to turn the Authentication property to On and then enter your thingspeak username and password. This is also interesting. ThingSpeak implements MQTT publish and subscribe functionality with QoS = 0. This "fire-and-forget" protocol means that your...

Hello Abhi,

Investigating for you now.

Please do not share login details.

Hello, Do you know what controller the display uses and what style of interface the display is using to connect to the RPI pins? Do you have a link to the display? You may find that the Pi already has a driver to be able to control the display and then you can simply use the existing GLCD RPI compon...

Have you applied the latest files and fixes from here?

If not then certainly that's worth doing.

Hello, I'm assuming your using the expansion numbering from here. https://www.matrixtsl.com/resources/files/misc/FA_Expansion.jpg To set the pin to an output you probably need to call this. ExpDDR(bitnumber,direction) bitnumber would be 8 for IO pin 8 on the FA_Expansion image and direction would be...

Hello, To program the Arduino boards you need to plug the USB B cable into the arduino itself, it cannot be programmed via the E-block. The arduino device should appear under the Ports section of device manager. In Flowcode select the port inside Build -> Project Options, then use the Build -> Compi...

Hello San,

Please can you attach your program so we can see what you're doing. Do you have external pull up resistors on the SCL / SDA pins?

Hello, I've had an email regarding this problem and so I thought I would copy the email reply here too for completeness. Looking at the project the first thing that jumps out is the pot_ptr_black Acquisition cycles is set to 1, this is the time to allow the ADC capacitor to charge before doing a con...

Hopefully solved for you now via the Help -> Check for updates.

Hello Fernando,

Investigating now for you, hopefully should be a quick one to resolve.

Hello Abhi,

Many thanks for letting us know, Hopefully should be resolved for you now via the library updates.

Hello,

Yes that's correct.

Hello,

Looks like you can simply use the Timer component available under data->storage to do a similar thing and get the time in microseconds. Then no C code nessisary

Hello, may I take that file - and stick it into the V8 Sorry this likely won't work, the easiest way to use in v8 would just be to use the SPI master component, the device is very simple to control. Initialise the SPI master component and then when you want to adjust the pot do this. Spi.jpg The QUA...

The new component is now available in v9. You can get the new components by clicking on Help -> Library UPdates and then changing Files in use to Full Database.

Let us know if you have any problems.

I think I may now be seeing the problem, the existing MCP41XX component is for the four digit MCP parts e.g. the MCP4131. It looks like we need a new component for the MCP41XXX devices as their command set is quite a bit different. I'll create a new component for v9 and hopefully that should allow y...

Digital pot arrived today so will have a go at getting it working for you.

Digital pot still not arrived yet, I'll chase it up with the purchasing team.

Assuming it's a quadrature encoder there is a component to help you with this. This wiki page has examples you can refer to. https://www.matrixtsl.com/wiki/index.php?title=Component:_Encoder_Rotary_(Inputs:_General) Here is a basic schematic for wiring the encoder to the micro to provide a bit of fi...

Hello,

We don't seem to have one of these devices handy at the moment but I have ordered one this morning and it should be with us early next week. If I can find a problem then I will fix it in both v9 and v8. Hope this helps.

Hi Bruno, First I would do a 1 second flasher test just to confirm you are running at the top speed of 64MHz. It could be the device is running slower then you think. If the device is running at the right speed then what rate is the master sending out the SPI, could this be slowed down? I have devel...

Hello Abhi, If you want to do the fix using C code then you can add this line to a C-icon after initialising the Modbus component. Odd parity on UART channel 1 U1CON0 = U1CON0 | 0x02; Even parity on UART channel 1 U1CON0 = U1CON0 | 0x03; Two Stop bits on UART channel 1 U1CON2 = U1CON2 | 0x30; For ot...
