ChibiOS Free Embedded RTOS

Hi, You need to consider that the PWM driver is mapped over a real TIM unit, the values you specify need to be compatible with the current TIM settings like: - Clock frequency. - ARR register value (the ARR value is your 100%). If your clock/period causes ARR to be something like "17" then...

Hi,

Try googling "__dso_handle undefined", several hits pop up.

It is not something that is part of ChibiOS.

Hi,

It is not supported, the driver transfers raw data.

When you launch OpenOCD it prompts you for an OpenOCD configuration file (not the .launch file just generated), files are under ./tools/openocd/scripts/board or ./tools/openocd/scripts/boards/target. If I remember well you should use ./tools/openocd/scripts/boards/target/stm32h7x.cfg This kind of th...

Hi, Lots of questions :-) About OO, HAL (and all the rest too) are written in an OO way just using C. Classes are structures, methods are functions that take the object as 1st parameter, virtual methods have a VMT (in classes with virtual methods), there are interfaces, inheritance (simple and multi...

Hi, So it is: CH_CFG_ST_FREQUENCY set to 1000 that prevents your application from working. Is there anything in your application that requires 10000? Post your mcuconf.h, it could be that 1000 cannot be obtained because your other settings. Anyway, I will make CH_CFG_ST_FREQUENCY unconstrained in 21...

Hi,

You should try those parameters on the GPL version and see if it shows the same problem, those parameters are already enforced on the "free" version.

21.11.2 free is not yet available, I could do that over weekend.

Hi,

You should check the guides on http://www.playembedded.org most things are explained there.

Hi,

You need to configure GPIO with appropriate alternate functions or nothing gets out, the table is in the STM32 data sheet.

Hi, The code is exactly the same, note that the commercial "free" version has some restrictions, it enforces: #define CH_CFG_ST_FREQUENCY 1000 #define CH_DBG_STATISTICS FALSE #define CH_DBG_TRACE_MASK CH_DBG_TRACE_MASK_DISABLED Make sure to keep those options the same. The only thing that ...
