Re: Getting Started

Hi StuntMonkeh, In transitioning from the Arduino platform to ARM, you will be amazed at how much more you can do. If you have not done much pure 'C' programming, you will find that to be something you will need to pay attention too. Specifically the facts that there are not setup() and loop() funct...

Re: Calculate an interval time

Giovanni, I looked over the Time Measurement driver. As I understand it, it is designed to work something like this: From a post by barthess: tmStartMeasurement(&itg3200_tmup); do some work here tmStopMeasurement(&itg3200_tmup); imu_update_period = RTT2US(itg3200_tmup.last); This will give a...

Re: Calculate an interval time

Hi Rocco, I have been playing with your functions and trying to add Magnetometer functions to it, looks like you are going faster then I am!! :D :D For real time duration between calls to AHRS routines you can use halGetCounterValue(). Just get the time at the start of your routine, compare it to th...

Re: ATMega328 / Arduino

I had a look but I'm not interested in embedding Chibios into Arduino, I'd like to just run native Chibios on an ATMega328 in the Arduino board. Hi Vik, I have also run through the process of working with the Arduino platform. What I have found is that is is good for a somewhat limited set of appli...

Re: Question about New Notepad Demo for ChibiOS/GFX

You are supposed not to get a smooth line. Inside the *_conf.h file of your ginput driver you fill find a polling delay macro. This defines the frequency with wich your touchscreen is polled. Otherwise the touchscreen polling would eat all your CPU. You may decrease this value to 2 or 3 if you want...

Re: [INFO] Call for Maintainers and forum changes

I am not a Git expert, but I use it regularly for my projects and find it works well and is easier to use then subversion that I used many years ago. I have some questions: 1) How do I branch release trees? do I need a different central repository for each branch? I need to keep history for each sta...

Re: Shell, MEMS & USBCDC

oohhhh..... Nice looking demo.

I was working on something to read and manage the onboard devices, but have
been caught up in the details. This should help a lot!!

Thanks

Re: Comunicazione Seriale

Avete copiato l'intero progetto, o solo il file principale fuori del programma demo? Ci sono molte opzioni di configurazione che sono necessari per far funzionare il driver Serial. Inoltre, ciò che errore hai preso? Al fine di aiutare, abbiamo bisogno di ottenere quante più informazioni possibile....

Re: Comunicazione Seriale

Scopri il programma di esempio in C: \ ChibiStudio \ chibios \ testhal \ STM32F30x \ UART. Inizia con questo e vedere se fa quello che ti serve. C'è un sacco di roba di configurazione è necessario imparare per il futuro, ma questo programma di esempio permette di iniziare rapidamente. Fare un tent...
