Flowcode Support Board

Hello,
Could you check the BMP280 component it can not be compiled with ESP32.
only added Init macro make failed compile. Thx for you prompt reply

Hi Seb,
Thank you for the spot.
Can you give the attached component a try, please?
In file explorer address bar, paste this: Save the attached file into the above hidden folder.
Just select ok to replace the current file.
If you got Flowcode running when the file was placed in the components directory, you must select the reload icon before compiling again.
If it works for you the component will be added to the updates.

Hello Martin,
Thx yes now can be compiled and value can be read from sensor but ,
I saw a strange problem when make a string calculation before to send the string to UART.
That calculation result is wrong even if in simulation the result is good. simulation result But When send the String SerialString to device from UART, there is always only 22 characters sent
I did different test with different begining of the String to see how it affect the calculation as you can see there is always 22 characters
/*BarometricSensor,9*/ is 22 characters
/*Sensor,982.88,977.*/ is 22 characters
/*B,976.7,1009.58,20*/ is 22 characters
as you can see, the 2 end characters "*/" are present but the middle is missing
Then I did a test without the 2 last characters result is 25 characters : /*Sensor,983.73,977.20.93
then Changed the beginning of the string "sensor" by "BarometricSensor" to increase the string length
result is 25 characters : /*BarometricSensor,920.74 The string is always incomplete and If the string is without "*/" at the end, the length is 25 if with "*/" the length is 22 characters

I did a test with a different way of the string calculation With this way, the string is complete: /*Sensor,984.57,977.68,20.83*/
Even is the beginning of the string is longer
10:08:57.205 -> /*BarometricSensor,982.32,977.74,20.84*/

Could you check what is the problem please . May be there is a link with TMP String Size.
thx

hi
please also check the altitude calculation who is wrong
thx

Hi.
The altitude (in feet) is not that much different from this website calculator: The Altitude is just a calculation purely based on the pressure reading.
As the pressure changes, it won't show a true fixed height above sea level.
Note, the Average sea-level pressure is 1013.25 mbar, so at that pressure, the Altitude reading will be around 0.
What I did was if I wanted to measure the difference in altitude, I would tare the altitude to 0 then any pressure change would then be converted to Altitude.
The example that shows that, can be found here

thx
But you didn't reply to my previous remarks and questions to this topic sir
viewtopic.php?p=5603&sid=b76f0dfd815efa ... f45b#p5603

I have not had time to look into it yet.
As soon as I do, I will post a reply regarding it.

ok thx

Could it be your terminal software?
I just tried your flowchart with both Tera Term and RealTerm
The results for both when sending via TTGO: & All looks complete to me.

did you tried with the 1st calculation enabled and the second calculation disabled ?
From my side I also tried with Putty and result is wrong too
