Hello
the heart of the BBC micro:bit is the nRF51822 SoC from Nordic
So is there a way to directly program the Nordic chip ?
while using the microphyton (Basic Python microbit or Upycraft)
Thank you for your answers.

What do you mean 'directly program' the chip? What are you trying to do?

Hello
Good question
That means:
_Use the same programming tool (Upycraft or Mu)
_Use of a minimum target (only a NRF51822 placed on a minimal module)
_Uses a minimal hardware interface between the USB port and the Nordic module (Convert USB / SerialTTL or more complex)
Best regards

What are you trying to achieve?

I want to create a "real" project after having tested it on the microbit card.
But The Microbit card is too luxurious and especially too expensive for my project.
I only need a very small number of inputs / outputs

There are development boards with the nRF51822 chip available really cheaply, and I had some luck programming them with a jlink-compatible programmer over SWD. I think that the micro:bit itself has the SWD pins exposed as pads somewhere on it, but I'm not sure which ones they are — some research might be necessary.

Maybe we can cut the connections on a microbit card and send them to another card with a nRF1822 only ?

Somebody flash a nRF51822 with a STLINK V2 and OPENOCD
I need it for flashing the Microphyton firmvare, but after, i only need to transfert python script.
