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.

This is quite thrilling.
Could you share some information about the price and the features for this new chipset?

Hello,

Currently scheduled for mid November

Any news yet?

I have a variable array, let's say data[20]. These are filled with data. In this array I need to find the first 0 byte. So if the array looks like data[1] = 11111111 data[2] = 11111111 data[3] = 110101 0 1 data[4] = 11010101 data[5] = 11110111 ..... This has to return the 2nd bit of the 3th byte. Th...

Looks impressive
Great work!

In some 3D design software there is a timeline that you can use to return to a previous state of the project. All changes are recorded on this timeline. This would be a nice feature in a program as Flowcode too. After a few hours fiddling, and when you find out that the changes don't work, it would ...

Hello, Thanks for the comments, there are some great ESP32 boards available now. I can confirm ESP32 is coming very soon (likely the next few months). Few months... july 8th... :-) Almost now then? :-) Can you already lift the tip of the veil a bit? What functions we can expect? What is going to be...

Another idea - use the CAL_UART component - there are Receive Array / String macros with a timeout. Just used with dfplayer and seem to work well... Thanks MNF.. I've tried (almost) all your suggestions, these and the suggestion from BenJ : https://www.matrixtsl.com/mmforums/viewtopic.php?p=102744#...

It's possible but not easy. You could busy wait watching the rx pin for a change of state and then receive - we managed this for the j1850 bus (effectively receiving data at 9600,baud) but timing was tight.. Use an Arduino mega. It has multiple tx/rx and this makes life much easier for debugging pr...

Hello, This question has been asked many times I guess, but in a project I use the software UART (because the hardware UART is used by a USB/RS232 connection). This means that the Arduino can't use the interrupt for data appearing on the digital inputs that are used for the software UART. Enough sai...

Hello, Would this do a similar thing for you. The first icon removes content from the buffer until it finds the text "ABC" Then we skip over the bytes were not interested in "987" and return the byte we want. CB_Demo.jpg Then this would be left in the buffer "543210%%%%%%" Otherwise what your sugge...

Are you using the SendChar macro? This should send the 00. If you use SendString the 00 will be considered a string terminator and not transmitted.

Thanks Kersing, I found this to be true.
Would a variable terminator string wouldn't be an addition to this component?

Me and the circular buffer will never be a good match. I don't know why but this never seem to work when I try things with it. A great addition for me would be a "find and return" action that can be used in this macro. This would search in the buffer for a certain string, and return the X'th value b...

If not got an analyser working, you can use Tera Term to view bytes instead of ASCII. It needs to run in debug mode: As you can see the 0x00 and 0x18 is not displayed as I believe the compiler is treating the 0x00 as a null terminator. Hey Medelec, this is true! If I send the data like I wanted to,...

Yes 4 in a row if always the same value. I was assuming the value would vary? If that was the case, store as ulong then send bytes within a loop. I can't take credit for this, but you could even send in a string like this "\xFF\xFF\xFF\xFF" Thank you, I will try this string way of sending. I first ...

Hi MJU, What about using flowchart posted here to send ULong to UART rather than to EEPROM? Thank you Medelec, But in that example you want to write 1234567890 to the eeprom. For that you need to separate the ULONG number to 8bits and store them in the EEPROM. But if I only want to store 0xFFFFFFFF...

BTW: is sending 0xFFFFFFFF the same as sending 4 times 0XFF in a row?
How do I send 0XFFFFFFFF via UART?

Hello there, I don't have access to all my resources right here and that confuses me. I'm playing with a device that has this in it's " datasheet ": UART1.jpg Is this the UART component that I need to use? 57600bps seems UART. But the 10bit confuses me. I don't have a working logic analyser here so ...

Take a look here: https://www.vishnumaiea.in/projects/hardware/interfacing-r307-optical-fingerprint-scanner-with-arduino This looks very good! Thank you Martin. I'm glad there are people left who investigate stuff and take their time to writ about their findings. This website tells me more about th...

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 (...

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...

I haven't read the whole post, but I recall a problem with RS232 in V8 too. In this thread: https://www.matrixtsl.com/mmforums/viewtopic.php?f=76&t=21964&p=100362#p100362 there are remainders.. I made the flowchart that I was working on in V7 and this worked well. I promised to share that V8 file la...

In this topic (from 2017): https://www.matrixtsl.com/mmforums/viewtopic.php?f=7&t=19151&p=89884&hilit=fingerprint#p89884 There was someone requesting a fingerprint sensor component. I've ordered a Grow R503 sensor (I've had an earlier model, but there was something wrong with it before I even got it...

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...

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.
