NIIET K1921VK: development platform for PlatformIO

Usage

1. Install PlatformIO
2. Create PlatformIO project and configure a platform option in platformio.ini file:

Stable version

[env:stable]
platform = k1921vk
framework = k1921vk_sdk
board = ...
...

Configuration

platformio.ini example:

[platformio]
default_envs = release, debug

[env]
platform = k1921vk
board = kfdl441546
framework = k1921vk_sdk
board_build.f_ext = 12000000L # OSECLK_VAL 
board_build.clk_select = pll #pll - SYSCLK_PLL , internal - SYSCLK_OSI , external - SYSCLK_OSE
debug_tool = stlink
upload_protocol = stlink

[env:release]
build_type = release

[env:debug]
build_type = debug
build_flags = -DRETARGET

• board_build.f_ext - frequency of external clock source (qurtz oscillator)
• board_build.clk_select - select clock source for sysCLK
  • pll - define SYSCLK_PLL, pll use external clock source and set sysCLK to 100Mhz. pll mode supports board_build.f_ext only with values: 8000000L, 12000000L, 16000000L, 20000000L, 24000000L
  • internal - define SYSCLK_OSI, use internal clock source. K1921VK01T: 5 Mhz, K1921VK028: 16 Mhz, K1921VK035 8 Mhz
  • external - define SYSCLK_OSE, use external clock source
  • custom - nothing define, you should configure clock by youself
• debug_tool - you can use for debug stlink
• upload_tool - you can use for upload stlink
