Firmware
Use Arduino as ISP
There is sketch in the arduino IDE, for the wiring in the description should be:
| pin name | not-mega | mega(1280 and 2560) |
|---|---|---|
| SS(Slave Reset) | 10 | 53 |
| MOSI | 11 | 51 |
| MISO | 12 | 50 |
| SCK | 13 | 52 |
upload the sketch and use Avrdude to test it, and should success on following picture
Burning bootloader
- Tools you will need:
- USBASP programmer: in our test, it's much faster than the USBtinyISP, don't know really know why, burning with usbasp only need 5-10 seconds, but usbtinyisp need around 1-2 minutes
- ISP 10-6 Pins converter: It's really helpful to convert ISP 10 pins to ISP 6 pins, and also help you to remember the pins for ISP-6, because the silk print indicate it! Works for all the ISP-10 programmer.And Arduino only have 6-pin ISCP connector
- Your arduino board: The MCU is already on the board and need to be programmed.
- Connect the programmer with the converter like below, only need to remember MISO is always to PIN1:
- Connect the board with USBASP to your laptop and burn, no need USB connect to the board anymore
upload sketch normallynow
Burning bootloader with other programmer, directly via hex file
Use Avrdudess programming
You can find the avrdude we used here.programmer
Flash use avrdudess GUI
Deploy arduino
- complied code and find file for example named "nrf24duino_start.ino.with_bootloader.hex" in folder C:\Users\Administrator\AppData\Local\Temp\arduino_build_981353
- flash write into MCU
- pro mini fuse set, L:0xFF, H:0xDA, E:0xFD, LB:0x0F

Specifications
the relationship between voltage and speed
Tips
Fix auto upload manually
- Hold down the reset button when IDE show "compile ..."
- Release the reset button when IDE show "uploading ..."
Extension
Documents
- STM32 Nucleo Toolchain use manual
- Eclipse extension with GCC toolchain
