Hi,
I am developing an application fro STM32F103VG evoprimer , I havent yet started doing coding/programming but have been reading ht eSTM32Circle forums for STM32 primer and Circle OS.I got to know the following things from my reading so far :
(1) It is the STM32F103VG based EVoprimer havnig LIS3LV02DL MEMS inertial Sensor
(2) There are three active interrupts -
- Systick Interrupt(Part os Circle OS code) invoked by the Systic Timer.It controls/affects the components like LEDs, buttons,Buzzers and LCDs
- Timer2 interrupt which has higher priority than Systic Interrupt and is responsible for invoking MEMS handler
- DMA interrupt - used for doing I2S transfers towards audio codecs
(3) SPI is used to control the MEMS from the TIMER2 interrupt @fixed rates
(4) CircleOS APIS are used to get the sensor info from the MEMS h/w.
Plz assit me how to proceed for development for the MEMS based application for evoprimer. Basically any tutorial/code snippet/ Block diagrams of these interrupts connected to MEMS hardware.Which APIS/Libraries or Circle APIS to look for .
PS : I have installed the Ride 7 version and Rkit - ARM tool kit (lates ) and licensed it and made teh system ready for application development.
Rgds,
softy
