Hi, I'm using ADC1 and ADC2 of a STM32F303RE in dual regular simultaneous mode. Each ADC should sample 5 independent channels and a sampling cycle is triggered by software, so I don't use continuous mode.I do get DMA interrupts and everything seems t...

My STM32F303RE is running with an 8MHz crystal feeding into HSE:Using TIM4 I want to generate 700 interrupts per second, but I only get 318.As can be seen TIM4 runs at 64MHz and the following configuration should trigger about 318 interrupts:Using th...

Hi, I'm using a STM32F303 with 10 independent analog input channels connected to ADC1 and ADC2 (5 channels per ADC).What I'd like to achieve is a software triggered scan of all 5+5 channels in one go and have the result copied to memory using DMA. So...

Hi, I'm using STM32CubeIDE to develop firmware for a small appliance (using STM32F303) in C++, but I'm in troubles related to the build process, caused by generated files like stm32fxx_hal_mps.c including C++ headers, while being compiled with gcc.Wh...

Hi,I'm having some hard time setting up my STM32F303RE Nucleo board for using the ADC.What I want to achieve is...scanning 10 sensors (each connected to a GPIO pin on ADC2) in sequence three timestransferring the data using DMA to a buffergetting cal...

Ok, I found the reason - my ADC wrapper was not that singleton as it should be.

*** me - it was a bug. Deep in my code I disabled the interrupt and restarted the timer.Thx for your support, guys - I learned a lot !

Now it's getting really weird.The ISR only gets triggered if I use the PLLCLK as the clock source for SYSCLK. Once I switch to HSE or HSI nothing happens.

My SYSCLK is fed from PLLCLK and both are at the correct frequency, measured using MCO and an oscilloscope an a counter.Still, the interrupt frequency stays at about 0.45 of what it should be, independent of the counter settings. And the problem is n...

I changed the timer config to get 100 Hz, but only measure 44.3 Hz. The factor between the expected and the actual frequency is constant over a wide range of timer settings - it stays around 2.2, so the expected frequency is 2.2 times the actual freq...
