Which pins do I need to use to program with FTDI?

[Mediusatra]

I am using a 1822 chip and I need to use it in a very small application so I need to program it separately from the main device. I have a learn.adafruit.com/.../overview FTDI friend which I was planning to use to program the chip with arduino code, similar to the DEV kit. I was wondering which pins i need to program the chip and which ones correspond to the pins of the FTDI?

EDIT: This is for a project that requires a PCB design so dev kits for the programming arent an option.

You can't program a blank nRF51822 with a USB to serial converter like a FT232

You need a SWD programmer, like a JLink or a STLink, or a Blackmagic probe (or many others)

JLink is the programmer used by Nordic's SDK, but with some work you can use other programmers.

However if you are comming from the Arduino world with little experience in microcontroller development, you should buy something like Nordic's own development kit (board) which comes with built in JLink, or a product that includes a SWD programmer e.g. take a look at the RedBear Lab products.

The project is for a design class so we have to have our own PCB made. I have the developer kit and have a working code on it. I just need to be able to program the PCB that is being made which has to be small, which is why I want to use external programming.

Buy a JLink Edu.

@Mediusatra: If you have a nRF51 or nRF52 DK, then you can use it to program external nRF5x devices.

[bjorn-spockeli]

As long as you expose the SWDIO and SWDCLK then you can program any nRF5x chip with the nRF5x DK. You will have to do this anyway if you want to use a J-Link to flash the custom PBC with the nRF51822. As Roger has stated, we do not support programming over a serial interface. ( unless you use our serial bootloader, but you still have to flash this using a J-LINK).
