|
This example program sends some characters on USART1.
|
|
Afterwards it connects to an STTS75 sensor (ST LM75 compatible)
|
|
at adress A0/1/2=0 and sets reverse polarity, 26 degree Tos and Thyst.
|
|
It reads out the temperature and submits the temperature over USART1 in
|
|
binary format (ASCII 0/1).
|
|
|
|
The terminal settings for the receiving device/PC are 115200 8n1.

Building
|
|
--------
|
|
|
|
$ make
|
|
|
|
Running 'make' on the top-level libopenstm32 directory will automatically
|
|
also build this example. Or you can build the library "manually" and
|
|
then run 'make' in this directory.
|
|
|
|
You may want to override the toolchain (e.g., arm-elf or arm-none-eabi):
|
|
|
|
$ PREFIX=arm-none-eabi make
|
|
|
|
For a more verbose build you can use
|
|
|
|
$ make V=1
|
|
|
|
|
|
Flashing
|
|
--------
|
|
|
|
You can flash the generated code using OpenOCD:
|
|
|
|
$ make flash
|
|
|
|
Or you can do the same manually via:
|
|
|
|
$ openocd -f interface/jtagkey-tiny.cfg -f target/stm32.cfg
|
|
$ telnet localhost 4444
|
|
> reset halt
|
|
> flash write_image erase i2c_stts75_sensor.hex
|
|
> reset
|
|
|
|
Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
|
|
replace "stm.cfg" with your respective config file.
