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.

Hello,

Release date was rescheduled for today however we had some Covid related problems where we lost some time and so we are now aiming for Monday. Fingers crossed.

Hello,

It's hard to know whithout seeing your code, are you reading the port register on the IOC interrupt and when arming the interrupt? Without doing this the interrupt won't fire.

Hello, I've had a quick look and it looks fairly straightforward. You need to pay attention to the DVI pin when initialising, this needs to be pulled low for at least 1us before pulling it high to startup the device. Page 10 of the datasheet shows how to write a command op code and how to read a mea...

Hello,

With nothing selected just look at the properties window.

Hi Martin,

The fast library - defines CASET and RASET to be 0..240 (for the whole display) - whereas I would expect this to be 0..239

Yes agreed

Sounds like your having good progress.
