Hey Giovanni, yes the DMA should be correctly programmed. And works fine. Only if a message is incomming from USART1 and the PWM is High, that looks like reset the PWM. Here are the DMA configs to load stuff into the BSRR of PortD PWM Defines: /*******************************************************...

Hello, everyone. I have a little problem with the PWM on a STM32L475 It seems that an incoming UART message resets the PWM, but only if the PWM is currently in HighLevel. Background. I have implemented the PWM once by interrupt and once by DMA request. The goal should be to set a GPIO port via the B...

oh sorry i was blind
yes, problem solved thanks for the support.

Hey Bob, no, ive not disable the compile warnings. Do you know, what is the bug in stm32_exti16-35_38.inc? in my debugging session ill only jump in vectorF4 and than in unhandled exeption. You mean stm32_exti19_21.inc, right? But this exti lines are not use in my case and will be not used, if we not...

Hey Bob, thanks for your answer. Ive disabled the makro functions in the ISR to rule out the problem, no change. For the EXTI line 16 exist three Handler could this the problem. the ISR is not even called but jumps directly into unhandled exeption when the Line 16 is configured and the threshold vol...

Hey Giovanni, no brakepoints are triggered. -O0 is active and i also active the asserts and checks in osalconf.h, because i jump into unhandled_exeption if i reduce the vdd voltage below 2,9V. config function will be execute after halInit() thats my config: mcuconf.h #define STM32_PVD_ENABLE TRUE #d...

Hey Giovanni, thanks for the fast answer. Now I have create a function macro for the ISR, but i could not yet see the voltage drop at VDD, if i reduce the supply voltage to 2.2V at PLS Level 6 (2,9V). I may not have masked the EXTI LIne 16 correctly and i am trying the extiEnableline function, later...

Hello, i use STM32L475 and i will enable the Peripheral Voltage Monitoring (PVM) on my STM32L475 and config the EXTI for getting an interrupt, if the voltage go under the threshhold voltage. So my problem is, how can i config and enable the internal EXTI Event on Line 38 (VDDA detection). in best ca...

Hey Giovanni,
thanks for the reply.
No i have used the previous Verison of ChibiOS.
So i have update now and use the debug generation tool. It works now.
Thank you .
