I have TIM1 configured in OPM mode to generate N PWM pulses on my STM32H743 chip. I need to start another timer at the start of every PWM period so I can generate a short pulse on a GPIO pin with TIM3 timer in the middle of the "high" pulse of the P...
Hello,Since the last update of STM32CubeMX 4.26.1, I can't open my project file anymore.Right after clicking on the 'open' button, the software freezes and one of the processor cores stays at 100%. The only available action, then, is to close the app...
Hai, I am using stm32f429igt controller I am trying to use IAP and found one example with stm32f4 cube package. While trying the example the code is not getting uploaded when I tried to upload it still waiting for the file can anyone help me how to s...
Recently we bought the STM32F769-Disc0 development board. We want the source code of demo project and how to compile the code in ubuntu 18.04 or any versions of ubuntu.
Hi,I'm working with an STM32L073RZ on a custom board, using MbedOS 5.12.0 bare metal. The board is a very low power weigh scale that is normally in Standby mode and is awoken by an accelerometer (connected to PC_13), an NFC chip (connected to PA_0). ...
On an STM32F429ZI, I'm using USART3_RX to receive information via DMA into a circular buffer. The buffer is 4096 bytes long.If I send 1 or 2 bytes at a time (i.e. with a delay of ~100ms+ between transfers), things work correctly. By "work correctly" ...
Hello,I am trying to synchronize two PWM outputs on an STM32H7: TIM4 channel 2 and TIM8 channel 3N.To do this I am using the HAL synchronization functions, setting TIM4 up as master with "HAL_TIMEx_MasterConfigSynchronization" and TIM8 with "HAL_TIM_...
Hi everyone ! I read in the datasheet that I need the VREFINT_CAL to calculate my real VDDA but I don't find it in the datasheet. In every other model's datasheet you can find the VREFINT_CAL easily but not in the STM32L0 one. Is someone kno...
I'm trying to use both internal op-amps to sample analog inputs with ADC1 and ADC2. When the op-amps are setup using CubeMX (latest version), 3.3v stays present on PA6 input. PA0 works as expected. Both ADCs sample correctly but the waveform input th...
Hello,we want to build a system with STM32H7, hopefully one of the new up to 480 MHz devices. And we really need a high clock of 400 MHz and above. On the other hand we need low power and we use ADC and DAC, both requiring a 3.3V Vref.Now my question...
