Re: ESP8266 as target chip

We hope to be supporting the ESP32 device as a target in the near future. This has a core dedicated for handling the WIFI/Bluetooth software stacks and a separate core for running your program. We have recently revisited this and made big steps forward. The ESP8266 for us is currently better suited...

Re: 32bit replacement for Arduino (cheap)

Thank you, the ESP32 is a nice replacement for Arduino.

But, I'll wait until the device is supported by Flowcode before I purchase some ESP32 boards.
I hope the device can be used with all of its functions.

Re: 32bit replacement for Arduino (cheap)

Hello For stm32 I am currently using the chip STM32F030RC with 256K. You can find china pcbs for less than € 2. This chip represents the economic line of ST but has discrete performance. If you want something more powerful you can move on the F4 line. For example STM32F411CE with 512K and excellent...

Re: 32bit replacement for Arduino (cheap)

Thank you BenJ!

The ESP32 would be great as a supported chip, but this is 4 years old already.

Do you have an idea when it will be supported in FC8?
The STM32 boards, I'm going to check these out.

Any more suggestions?

32bit replacement for Arduino (cheap)

I caught myself to have ordered many Arduino-like, Chinese, develop boards. These are very cheap and they are very compatible with the Arduino software AND with Flowcode. But these boards are old-school hardware. I have the Flowcode 16 bit PIC license, the AVR and the RPI license. Is there a cheap d...

Re: Circular buffer question (waitforvalue)

Hi I've just upgraded the machine I used to test with to latest FC8 version (8.2.x) including files and it resolved my RXINT0 Interrupt problems. I thought I'd done this already but the process hadn't completed. Maybe that was throwing a spanner in the works, but I can now confirm that the interrup...

Re: Circular buffer question (waitforvalue)

I've made a flowchart with FC8 that uses the circular buffer which is filled with data from the UART with an interrupt, and this doesn't work. I've made a similar flowchart in FC7 with almost the same functionality, and now the "waitforvalue" works fine. Frustrating because I would think that these ...

Re: Data Injector issue

If the interrupt on RX is not working in hardware this maybe the reason that some of my projects don't work. I use this interrupt and sometimes it works and sometimes it doesn't work. Can someone please confirm that the UART RXINT0 function in Flowcode works?? Certainly in Arduino Nano which I'm usi...

Re: Circular buffer question (waitforvalue)

Hello, My first guess would be the UART baud rate or something similar is off. Have you confirmed the micro is running at the speed you think it is using the 1 second flasher test. Another thing is to check the UART receive interrupt is enabled AFTER the UART is initialised. Lastly The waitforvalue...

I've made a flowchart with a an interrupt where I "receive a character" on the UART RX-pin (timeout = 0) and put this byte in a circular buffer. This interrupt is enabled throughout the whole flowchart Somewhere I need to check if a certain value "Ack" is received. I try to do this with the "waitfor...

Re: Use return from macro

The macro call will be the value. So if Macro_1() then In a decision you just enter 'Macro_1()' for the 'if:'. If your macro requires arguments (say 2) you enter 'Macro_1(1,"second")' or 'Macro_1(.var1, .var2)' if you want to pass the values of local var1 and var2. Thanks for your advice! Again! :-...

I've got a macro (lest say: Macro_1), and I've made a local variable .Return In the macro, I set .Return to 0 if something didn't work, and to 1 when it ran successfully. From what I've read the .Return should now be used globally to check if the macro ran successfully? How can I check in another ma...
