Hello, Here's a quick example for you to play with, let us know how you get on. MQTT_ESP8266.fcfx You can connect to the Thingspeak MQTT servers or you can create your own MQTT server using something like Mosquitto on a raspberry pi. https://randomnerdtutorials.com/how-to-install-mosquitto-broker-on...

Hello, Looking at the datasheet I wonder if enabling the peripheral interrupts would make any difference. Looking at the block diagram it suggests it's not required but it's worth a go to see if it improves things. Using a C icon add this to the start of your program. st_bit(INTCON,PEIE); This is au...

Thanks for letting us know. I have hopefully now fixed the problem and pushed the change to the update system.

Hello,

Maybe worth increasing the reply delay to ensure the transmit state has time to ripple through to the master?

In your Modbus_Slave_2 macro each write is to the same holding register 0.

This should work, It's what the Lookup table component generates.

Hello,

Can you use the LUT component available under storage, this effectively creates a ROM based array you can call directly within the flow chart.

Hi Abhi,

Can you post your program and we will have a look for you.

the following lines might be better as

floattemp = float - FLOAT intwhole
floattemp = floattemp * 1000.0

Hello, Let me see if I'm reading this correctly. You would have a single PIC device with a connected display operating as the Master to two sensor devices. Yes this should work fine if either both sensors have different I2C addresses or they are on seperate I2C channel pins. Another thought I had wa...

Hi George, I have made a component I'm now fairly happy with, it works with the Easy CAT shield but will work on any target microcontroller. I've also been looking at open source master libraries that will run on a PC. Do you have a particular master controller in mind or is it speculation at the mo...

Hello Stefan, This could mybe be an ANSEL register problem? Please can you try the following code in a C icon and see if it makes any difference. CHange the register name and bits to match the ADC inputs you're using in your program. ANSELBbits.ANSB0 = 1; ANSELBbits.ANSB1 = 1; ANSELBbits.ANSB2 = 1; ...

Hello, Thanks for sharing your findings, the accelerometer does seem to be rather noisy. Have you tried turning down the sensitivity from +/-2G to say +/- 16G and seeing if you get more sensoble values. The compass initially looks bad but then sems to get much better and the gyro looks good. I wonde...

Hi Allen,

Aha thanks for letting us know, yes this is a bug in our definition file. I've now fixed it and will push the fix to the update system. You can get the fix by using the Help -> Check for updates menu.

Hello, You can use any I/O pin to drive the display. We could add a feature to the component to drive the data pins as a port byte and this would be a little bit faster. But currently the component does not have this feature so it won't make any difference. On a PIC32 I doubt you would see much of a...

Hello, Have you confirmed your hardware is setup and running at the correct frequency with a 1 second flasher test. You will need to do this to ensure your UART baud rates are correct. https://www.matrixtsl.com/wiki/index.php?title=One_second_LED_flasher The values you have assigned to the holding r...

Hello, I'm thinking of supporting this Arduino shield, would that work for you. https://www.bausano.net/shop/en/home/1-arduino-ethercat.html I would also support the Easy Configurator software by allowing Flowcode to include the generated .bin and .h files. https://www.bausano.net/en/hardware/etherc...

Hello,

Yes that block diagram is very confusing but I beleive it is showing the ADC trigger pins and reference pins not the ADC input pins. ADC0 should be able to connect to all ADC input pins and then the result will go into the ADCDATA0 register.

Let me know regarding the ANSEL.

Hi Ronald,

It might just work and be compatible, it certainly shouldn't break anything.

Let us know how you get on and yes if you are having problems I'll share the source with you or help you to fix it so it works with the larger driver.

Hello ALlen, It seems it does work but you might have to force refresh the properties by changing another property after setting the channel, e.g. Use TX. Set the Use Tx to No and then back to Yes and the property list for the Remap pins should then refresh and give you the G0 option. It's a bug we ...

Hi Karthick,

I'm currently investigating this for the ESP32 hardware but should also be possible via an ESP8266. We already have support for MQTT which is very powerful. For Alexa type stuff there is ITTT which we are also looking into.

Hi George,

Good suggestion thanks. I'll investigate for you, could be a nice one to add.

Hello,

I've replicated the problem, started looking for you yesterday but then got pulled onto something else. I'll look again for you today.

Hello, The chip has multiple analogue pins and multiple analogue to digital converters. Currently we only support converter channel 0 but this should work with any of the analogue pins. We specify the analogue pin here. ADCCON3bits.ADINSEL = Channel; //Select ADC Channel It does however look like we...

Hi Gavin,

Unfortunatley I beleive they require a different toolchain to the STM32 and different CAL code so adding support for them is still going to be a large undertaking.

Hello, We are investigating the problem for you. However what about this for an alternative. Use something like a USB to Serial IC such as a FTDI or similar, then connect this to a UART on the STM32 device and then stream in your configuration using either a serial emulator which can be used to send...

Hello, We are currently working on adding a new chip pack for Flowcode in the form of a ESP32 device. We are also working hard on a new major version. The STM8 devices do look good and we have some here, I'll make sure they are still on the list for a potential future chip pack and see if we can fin...
