Hi Roy,

You might just be able to login with your existing details. I'm not 100% on the way the new site works so let us know if this does or doesn't work for you.

Yes I think v8 to v9 is a 50% discount.

Hello, If you are teting with a multimeter then it might be the pin is toggling on and off too fast for it to see 0V and 3V3. This is a good simple test to get you started and to confirm your configuration settings. https://www.matrixtsl.com/wiki/index.php?title=One_second_LED_flasher Basically what...

Hello,

Are you placing the code inside the interrupt icon and not inside a C icon? The %n is correct and will be overridden for you.

If you post a simple project with the code you have then we can take a look for you.

Hello,

For the list of chips and modules currently included see this post earlier in the topic.

No i2s at the moment but might not be too hard to add. I can get it on the list to investigate for you.

Hi Bob,

Looks ok to me. I've moved the duplicated code into a macro so you can just call the macro at various points.

Glad it's working well and compiling ok. Let us know if you spot anything that doesn't compile.

will there be an ESP32 eblock 2 upstream board with ghost available?

We don't have any solid plans for this yet but yes this might be on the cards for development in 2021.

Hi Gavin,

Things are now up here. https://www.flowcode.co.uk/

We will be making an official announcement soon once the site is a bit more polished.

Hi Bob, You cannot enable an interupt for a different macro. The way the underlying C code works only the first macro will ever be called. You can however enable the interrupt several times for the same macro, you can also reference global variables in the timer interrupt macro and so you can do dif...

Hopefully close now.

bug: Software UART baud rate on an STARM was not being calculated very well

Hello Alan, I've added Leighs fix to the v7 update zip file now. Going forward as we add new features and overhaul functionality it becomes harder and harder to apply backward compatible fixes. So initially we do it a lot but over time as less people are using the previous older versions we start to...

Hi Martin, I've had a good go through the datasheet and the SPI code and at the moment I can't spot anything that looks incorrect. Your program is very simple and so is the onderlying code so it's a strange one. This is the code that is included when transmitting a SPI value. unsigned int i; USISR =...

Hi Abhi,

Aha thanks good spot, should be fixed now via the update system.

Hi Chris, I would use a timer interrupt and maybe an edge driven interrupt. The edge driven interrupt would monitor the switch input and determine when the switch was pressed. The timer interrupt would monitor the passing of time. Assuming the interrupt fires on each switch state change, If the swit...

Hello, Here's a definition file that should solve the problem for A2 and A3. As there is no ADC peripheral on the device we haven't enabled it for any of the pins. 16F648A.fcdx Needs to be copied here. C:\ProgramData\MatrixTSL\FlowcodeV8\FCD\PIC I won't do an official release for this one as it migh...

Hello,

Here's a very much simplified version to transmit a UM3750 signal using Flowcode v8. The output pin and delay period are set via properties.

Let us know how you get on.

No plans for the ESP8266 at the moment other then as a external module. The toolchain is very different and so unfortunately it's not something that just falls out of the ESP32 work.

Hello,

I've added Martins fix to the official update release today.

Hi Clive,

You could try the ST7567 component and see if this works. If not then let us know and we can look into it for you.

Anything with an ESP32 at it's core will work but we currently have specific support for these boards. ESP32 DEVKITv1 ESP32 T-Camera - Currently no support for the Camera module ESP32 WROOM32 ESP32 WROVER ESP32S Heltec WIFI Kit 32 Lolin32 Lite LolinD32 Pro TTGO T Display Other boards can be easily a...

Hello, Were currently quite far on with support for the ESP and so the following things should hopefully work out the box. ESP WIFI component Network Comms Support - So things like MQTT, MODBUS TCP etc should work ESP Bluetooth SPP Slave Component Basic peripherals like I2C, SPI, ADC , PWM are all w...

I've written a v9 component for it now and can port it to v8 if it would be useful but there's not much code there so should be doable with the I2C master component.

Let me know how you're getting on and if your finding it tough then I'll see what I can do for you.

Hopfully fixed for you now

Hello,

I had a go at making something for you that did this but I haven't been succesful yet. I'll try again now.

Annoyingly the value is available as $(target) but I can't seem to access it outside of compile time and so may not currently be possible to do automatically.
