Arduino And Mbed Framework On Ble Sense - PlatformIO Community

Maybe your like

sherry November 27, 2020, 7:41pm 1 hello i tried loading the blinker example from mbed and i have ble 33 nano sense board from arduino. I get the following message mbed framework is not supported on this board when i searched i found that arduino supports mbed ? is it possible to run rtos with mbed on this board?thank you maxgerhardt November 27, 2020, 7:50pm 2 This is partly explained it Is there a functional difference between Platformio's "framework-arduinoadafruitnrf52" firmware and arduino's official firmware - #4 by maxgerhardt. The Arduino core for this board is framework-arduino-nrf52-mbedos which is actually an implementation of the Arduino core API on top of a specific mbed-os. The mbed-os part of it is still fully functional. Have a look at GitHub - arduino/ArduinoCore-nRF528x-mbedos: [Archived] Arduino core supporting mbed-enabled boards. sherry November 27, 2020, 10:31pm 3 thank you for your reply, i am aware of ArduinoCore-nRF528x-mbedos but i still don’t know how can i use it from platformio, how can i use a special framework? maxgerhardt November 27, 2020, 10:35pm 4

but i still don’t know how can i use it from platformio

framework = arduino must be selected for that. It’s an Arduino core on top of mbed-os, after all. sherry November 27, 2020, 10:49pm 5 thats great but should i replace the arduino framework or is it a new framework with a new definition? sherry November 28, 2020, 7:48am 6 i noticed there is a framework called as follows in the packages folder .platformio/packages/framework-arduino-nrf52-mbedos is it the same framework you mentioned? how can i use it what is the environment name? maxgerhardt November 28, 2020, 9:36am 7

thats great but should i replace the arduino framework or is it a new framework with a new definition?

There is nothing to replace. By specifying framework = arduino PlatformIO will automatically select the corerct Arduino core for you. Example:platformio.inisrc/main.cppin the compilation output you will see the used packages. sherry November 28, 2020, 10:54am 8 Excellent thank you. Here is another sample for people who like to work with the mbed main function, the same program but written using threading.Summary: To recap, as soon as the mbed object is called, it will compile using mbed rtos although the framework in the setup is arduino. sherry November 28, 2020, 11:02am 9 The only still problem is: 1- although it compiles and flashes well, but i get under problems, thread_sleep_for is undefined, and P0_13 is undefinedit seems there is a missing header ? maxgerhardt November 28, 2020, 11:07am 10

1- although it compiles and flashes well, but i get under problems, thread_sleep_for is undefined, and P0_13 is undefined

Is that a compile error when using the Build button or an IntelliSense error? The IntelliSense won’t be able to find that framework files if you haven’t built it at least once, because then it will download the framework. Also when in doubt, use the project task “Rebuild IntelliSense” after a build.I can compile perfectly fine and the IntelliSense works. grafik

Like the documentation says, the board doesn’t have an on-board debugging device. You need an external SWD debugger device like a ST-Link (or general CMSIS-DAP), JLink or Black Magic Probe and connect it to the board’s SWD pins (SWDIO+SWCLK+GND,RST,3V3 ofc), which are on the back of the board
