Re: Fingerprint sensor terminology

Thank you Martin! I had a quick look at the datasheet of that GT-511 fingerprint sensor. But the thing is that I don't really understand the terminology. What do I need to perform to get the thing working. In what order. There will be differences in how different modules work, but in the datasheet (...

Fingerprint sensor terminology

I've been reading the datasheet for the R503 fingerprint sensor (GROW) for a while. (https://www.dropbox.com/sh/epucei8lmoz7xpp/AAAmon04b1DiSOeh1q4nAhzAa?dl=0 ) This is a Chinese device and the datasheet doesn't give me all answers I need. There is different terminology and there aren't examples for...

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?

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.

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.

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 ...

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.

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...

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! :-...
