FireBeetle ESP32 and Arduino 1.8.4- DFRobot Forum

2017-08-31 23:24:15 From the manual pdf.......
---------------------------------------------------------
"Once the upload finishes, open the built-in serial monitor of Arduino IDE, touch D9 with your hand
(T2 corresponds to D9) print 1 show below
Code analysis:
Obtaining GPIO state of the capacitance sensors only requiring calling touchRead. The antitype
of touchRead is as below:
uint16_t touchRead(uint8_t pin)
0 means no touch, 1 means touch. From T0 to T9 are pins, the corresponding pins of Firebeetle
shown in the list as below."
--------------------------------------------------------------
This T2 is the only one that does this..... Is it in some other mode of oreration...?????
The rest of the touch pins change from say 350 to 25 when touched....?????

I dont get any response when T1 is touched.... it reads 1 always.....???? It it already connected to other components on board...???

From the manual pdf.......
---------------------------------------------------------
Caution: Please do not use T8/T9 for touch input. They have already been connect to outer crystals
of 32.768 KHz.
-------------------------------------------------
So does this mean T8/T9 can not be used for touch at anytime...?????

If I dont need the realtime clock to keep real time can the crystal be removed or put on other pins..???

Is there a schematic diagram available for the board....???? kington

2017-08-31 21:29:56 I have tried the touch example sketch modified to test each touch pin. It all compiled and downloaded and run.
But T1 and T2 are reading very low values and dont respond when touched...???? also I cannot find pins for T8 and T9. According to the pins_arduino.h file in the board library it shoe T8=33 and T9=32.. I dont see IO32 or IO33 on the pinout diagram...??? Do the need to be enabled somewhere..??

Attached is screenshot of the sketch I am using and the terminal output corresponding kington

2017-08-31 09:22:29 This is a tree view of the FireBeetle ESP32 files installed by copying the link on setup tutorial to the addition board manager link field in Arduino preferences. All are installed in Document and settings/ .... etc../etc.../ .....Arduino15 folder

The files that the compiler had probblems finding are shown with Red pointers.

Just wondering are any other files/folders missing or in wrong place....???? kington

2017-08-30 09:23:04 The blink sketch does actually work now after copy in the missing files as last post. The blue LED is now flashing as per the sketch LED_BUILTIN is gpio2 or pin 2 in Arduino. The red LED only flashes momentarily when USB power is plugged in. Should it stay on when battery is plugged in and USB power is plugged in...???? kington

2017-08-28 22:37:51 I found a c++allocator.h file on internet and copied it in to the folder where it was missing.

also then it asked for gthr-default which was missing copied this over as well
There are 2 folders called bits is separate subfolders....?????

Now it compiles and seems to download as shown below.........
This below is from arduino IDE during compiling blink sketch and downloading also what was sent to the monitor terminal.

Before download the blue LED on the board was flashing at approx 1 second flash
On the FireBeetle board now the blue LED has stopped flashing and board appears to be doing nothing.
So dont know if it actually downloaded. The red LED flashes momentarily as power is plugged in.

I am still stuck, Thanks. kington

2017-08-28 20:57:42 The last bit of the last post is actually a snipit of the code in allocator.h file at line 46 ......showing the call to c++allocator.h

allocator.h is in the folder OK but c++allocator.h is not in the folder kington

2017-08-28 20:52:58 Thanks for your reply..........
I have been using the guidance on this web page. I have unistalled everything and reinstalled using this guidance again.

https://www.dfrobot.com/wiki/index.php/ ... U:_DFR0478

All installed without error. I used the Arduino 1.8.4 zipped download which gives a standalone install and entered the link in preferences for the board manager to install the firebeetle board.....all seemed to work without error.
The board install puts everything in ........ c:\documents and settings\yyy\local settings\application data\arduino15\packages etc etc ..... by default....I did not get option where to install.....but all seems to be there except this file it is looking fo...???

I attempted to verify/compile the sketch for blink and it gives me same errors and tells me C++allocator.h no such file ??
When I manually look in that folder it is not there.....so question what is it supposed to be looking for.
Is the call by wrong name ??????

2017-08-27 20:44:15 It seems that you did not include the proper library. Here is some information about how to add a library. https://www.arduino.cc/en/Guide/Libraries R2D2C3PO

Error compiling for board FireBeetle-ESP32.

I have followed the procedures in the tutorials and manual and can compile sketches for other boards OK ( not esp32 types)
I have tried various sketches. the output above is for the "blink" . I can see the boards in board manager and can see it in the com port device manager. I am using windows XP. kington
