|
|
* saving parameters to flash
|
|
|
|
####Directories
|
|
* hw/eagle/ Eagle board files and schematics
|
|
* hw/spice/ Spice simulation for resolver interface
|
|
* src/ STM32F4 code, command, feedback and control loop
|
|
* stm32f103/ STM32F1 code, running on the HV side, generating PWM
|
|

|
|
|
|
|
|
####Building the firmware
|
|
##### Requirements
|
|
* gcc-arm-none-eabi-gcc https://launchpad.net/gcc-arm-embedded/+download
|
|
* stlink https://github.com/texane/stlink
|
|
|
|
##### Flashing
|
|
Add gcc and stlink to your $PATH
|
|
|
|
make
|
|
make burn
|
|
|
|
####Building Servoterm
|
|
##### Requirements
|
|
* cmake >= 2.8
|
|
* gcc >= 4.8 or clang
|
|
* wxwidgets >= 3.0
|
|
* libserialport http://sigrok.org/wiki/Libserialport
|
|
|
|
##### Compiling
|
|
|
|
cd term/
|
|
mkdir build/
|
|
cmake ../
|
|
make
|
|
|
|
####Using Servoterm
|
|
##### Testing HAL
|
|
HAL can be tested without any hardware connected to the STM32F4discovery.
|
|
* Flash STM32F4discovery(STlink and USB OTG must be connected)
|
|
* Launch Servoterm, Click refresh, and connecto to STM32 Virtual ComPort
|
|
|
|
entering 'list' prints a list of hal pins.
|
|
The current default config is for a 4 pole AC permanent magnet motor with resolver feedback, using an encoder for command.
|
|
|
|
> net0.fb <= res0.pos = 0.000000
|
|
|
|
net0.fb is driven by res0.pos, and its current value is 0. Pins can be connected to other pins, or fixed values.
|
|
|
|
This example connects the sine wave generatror to wave view 0.
|
|
Offset and gain can be controlled with the sliders below Channel 1(black).
|
|
```
|
|
term0.wave0 = sim0.sin
|
|
sim0.amp = 10
|
|
sim0.freq = 5
|
|
```
|
|
To disconnect a pin, connect it to itself
|
|
```
|
|
term0.wave0 = term0.wave0
|
|
```
