Problem with ADC and DMA
Posted on July 13, 2018 at 22:03Hello community! I've got a problem with DMA and ADC (multi channel). I can't find solution why function HAL_ADC_Start_DMA returns 0's to the 'adc_value' array. I have connected to Nucleo F466RE board 3 sensors, and i...

KSZ8863 RMII Interface and STM32f207 Communication
Posted on November 09, 2017 at 20:22Hello,I am currently using HAL library to interface my STM32F207 to a KSZ8863 switch using RMII Interface. The clock 25 Mhz provided externally which is then scaled to 50 Mhz to enable the interface. Now, I can re...
Error handling for UART RX with DMA
Posted on January 15, 2018 at 11:00Hello!I am using RX DMA with RX timeout detection (based on Efficiently receive UART data using DMA). Under normal condition, everything works fine, but I have problems with the error handing. My MCU is the F302R8 ...
Adding TIM7 (timer 7) with interrupt using STM32CubeMX
I tried to add TIM7 via CubeMX with interrupt on NUCLEO-H743ZI.CubeMX was able to create the init for the timer in the code but it didn't add the IRQ, didn't enable the IRQ and didn't add its callback.I added this code manualy.What I'm missing?
Waking up STM32L0 from LPTIM interrupt
Posted on July 13, 2018 at 03:12I'm trying to put STM32L0 into a low power sleep mode. I want it to sleep for 9.5s and wake up for 0.5s. Once it's awake it needs to switch on LEDs, check for any interrupts from a Lora radio module and process the da...
STM32F303ZE software triggering of timers through the TIMx_EGR register
We are running TIM3 and TIM2 on a STM32F303ZE processor generating pulses on both timer outputs synchronous to an external input trigger. We have TIM3 configured for “Trigger Mode�? with the “External Trigger�? selected running in “one pulse mode�?. ...
How to use LPTIM in wakeup mode? L432KC
Hello. I would like to use low-power timer to wakeup from stop mode (1 or 2).My model is: start LPTIM, generate PWM from one TIM (general-purpose), wait for timeout in stop mode, then start LPTIM again, generate signal etc.I used demo for LPTIM (time...
NUCLEO-F746ZG USB device MSC example going into HardFault Exception.
Hello Everyone,I am using NUCLEO-F746ZG having STM32F746ZG mcu. I was trying the USB device - MSC_Standalone example provided with stm32cubef7. I am using SW4STM32 to compile the example code. The device detects the SD card but when i connect it to t...
