Hi Ben, Hi Steve Thanks a lot.It's working fine now. With the part "if file not can be open, then create", I understand. And that there is no command macro for file close so I use file open but with parameter 0 for read and write. I suppose that's what Ben means. I will continue to save and open lar...

Hi Ben I wrote a testprogram for the build in function File. It's working fast and with long filename. Only create with the file and close the file there is a little problem. So I first have to start the program with creat file and then close the program and switch off createfile when the program se...

Hi Ben

Flowcode has a component CNC Machine and Matrix has some CNC Machine on offer.
Is there a CNC machine that can be controlled with FC9?
Not to mill parts but to demo a machine.

Hi Lain Yes with this two commands you can set the maximal power for Bluetooth sending. Note I used exactly for the other direction, Bluetooth set to minimum power. It's in the program demodata includet. There is also an idea for the BT interrupt in ESP32, to make the inerrupt routine very short and...

Hi Lain Yes set the BT tx power. https://flowcode.co.uk/forums/viewtopic.php?f=4&t=1176&start=10 I made some test and Default powersetting is: ESP_PWR_LVL_N0 = 4, !< Corresponding to 0dbm ESP_PWR_LVL_P3 = 5, !< Corresponding to +3dbm I have now set to the minimum ESP_PWR_LVL_N12 = 0, !< Correspondin...

Hi Martin

Yes a link to your TTGO type would help.

If you can take a look with Ben at my post.
There is also an ESP32 not yet available.

Thank you

Hi to All

How can this be done with Flowcode? An idea?

Hi Ben In your video everything works so simply but.. I tried to control the DAC of the ESP32 with the DSP. Even on the beginn with the setting of the interrupt is not clear to me how that works. At the end there should be a sinus signal of about 1 kHz on the DAC output, so a 10 kHz interrupt freque...

Hi chipfryer Do you use a Bar or Disc? A little hint. There are already bars for measuring in the range of 0.5 kg. Of course, they are much easier to load because you can only measure a maximum of 0.5 kg, but practical on the laboratory bench regards Stefan https://www.sparkfun.com/products/14728 Lo...

Hi Martin I'm not sure what hardware you're using. I found a module with 20 pins in the ESP32 Pack from Flowcode under Supported Devices. But what hardware is that with 20 Pin? There are various small USB modules to program the ESP32. Some also support the reset pin. You no longer have to press the ...
