stm32

steps I took to get stm32nucleo mb1136 C-03 running in Arduion IDE on OSX 10.10 Yosemite

• no soldering/desoldering needed in my case.
• install Arduino 1.6.5 (don't use 1.6.6 or 1.6.7 because of [[https://github.com/rogerclarkmelbourne/Arduino_STM32/issues/147|errors]])
• tools -> board -> board manager... -> install 'Arduino Due'
• download [[https://github.com/rogerclarkmelbourne/Arduino_STM32/archive/master.zip|Arduino_STM32]]
• unpack to ~/Documents/Arduino/hardware/Arduino_STM32
• Install libusb from http://rudix.org/packages/libusb.html (in case of upload errors)
• restart Arduino IDE
• select tools -> board -> STM Nucleo F103RB (STLink)
• select tools -> port -> usbserial or usbmodem1234
• load Blink example
• upload Blink example
• to communicate with Serial Monitor in the Arduino IDE I had to use Serial1 (instead of just Serial). ([[http://stm32duino.com/viewtopic.php?f=3&t=512&start=20|more info]])

  • "Desolder the 0-Ohm-resistors on SB55 and SB54 (bottom right) to cut the trace. Solder a little bridge on: SB16(MCO) (top left) and SB50 (bottom middle)"

SPI_2

it is possible to use 2 SPI ports: Using the first SPI port (SPI_1) SS <--> PA4 <--> BOARD_SPI1_NSS_PIN SCK <--> PA5 <--> BOARD_SPI1_SCK_PIN MISO <--> PA6 <--> BOARD_SPI1_MISO_PIN MOSI <--> PA7 <--> BOARD_SPI1_MOSI_PIN

Using the second SPI port (SPI_2)
SS    <-->  PB12 <-->  BOARD_SPI2_NSS_PIN
SCK   <-->  PB13 <-->  BOARD_SPI2_SCK_PIN
MISO  <-->  PB14 <-->  BOARD_SPI2_MISO_PIN
MOSI  <-->  PB15 <-->  BOARD_SPI2_MOSI_PIN
