"Welcome to MicroPython!\n"
"\n"
"For online docs please visit http://docs.micropython.org/\n"
"\n"
"For access to the hardware use the 'machine' module. \n"
"\n"
"Quick overview of some objects:\n"
" machine.Pin(pin) -- get a pin, eg machine.Pin(0)\n"
" machine.Pin(pin, m, [p]) -- get a pin and configure it for IO mode m, pull mode p\n"
" methods: init(..), value([v]), high(), low())\n"
"\n"
" Pins are numbered board specific, either 0-n, or 'D0'-'Dn', or 'A0' - 'An',\n"
" according to the boards's pinout sheet.\n"
" Pin IO modes are: Pin.IN, Pin.OUT, Pin.OPEN_DRAIN\n"
" Pin pull modes are: Pin.PULL_UP, Pin.PULL_UP_47K, Pin.PULL_UP_22K, Pin.PULL_DOWN, Pin.PULL_HOLD\n"
" machine.ADC(pin) -- make an analog object from a pin\n"
" methods: read_u16()\n"
" machine.UART(id, baudrate=115200) -- create an UART object (id=1 - 8, board-specific)\n"
" methods: init(), write(buf), any()\n"
" buf=read(n), readinto(buf), buf=readline()\n"
" The RX and TX pins are fixed and board-specific.\n"
" machine.SoftI2C() -- create a Soft I2C object\n"
" machine.I2C(id) -- create a HW I2C object\n"
" methods: readfrom(addr, buf, stop=True), writeto(addr, buf, stop=True)\n"
" readfrom_mem(addr, memaddr, arg), writeto_mem(addr, memaddr, arg)\n"
" SoftI2C allows to use any pin for sda and scl, HW I2C id's and pins are fixed\n"
" machine.SoftSPI(baudrate=1000000) -- create a Soft SPI object\n"
" machine.SPI(id, baudrate=1000000) -- create a HW SPI object\n"
" methods: read(nbytes, write=0x00), write(buf), write_readinto(wr_buf, rd_buf)\n"
" SoftSPI allows to use any pin for SPI, HW SPI id's and pins are fixed\n"
" machine.Timer(id, freq, callback) -- create a hardware timer object (id=0,1,2)\n"
" eg: machine.Timer(freq=1, callback=lambda t:print(t))\n"
" machine.RTC() -- create a Real Time Clock object\n"
" methods: init(), datetime([dateime_tuple]), now()\n"
" machine.PWM(pin, freq, duty_u16[, kw_opts]) -- create a PWM object\n"
" methods: init(), duty_u16([value]), duty_ns([value]), freq([value])\n"
"\n"
"Useful control commands:\n"
" CTRL-C -- interrupt a running program\n"
" CTRL-D -- on a blank line, do a soft reset of the board\n"
" CTRL-E -- on a blank line, enter paste mode\n"
"\n"
"For further help on a specific object, type help(obj)\n"
"For a list of available modules, type help('modules')\n"
