Hi, I have issues while using "FATFS R0.12c" over SDIO on my STM32F407. I do SDIO write to file on main loop, but I also have "TIM2/TIM3/CAN1 RX0/CAN1 RX1" interrupts which has other logic (for example TIM2 sends UART message every 100ms to update th...
When both UARTS are transmitting & receiving, my ADC conversions (via DMA) sometimes do not complete. If I double clock speed (which I do not want to do in the product), the problem goes away. I cannot see any issues in my code that would cause this....
Hi everbody,I am using STM32L476 mcu with WLCSP72 package on my designed board. On this mcu PC5, PC4, PB14, PC13 and PB13 pins are configured as an output-pushpull. The problem is, when the PB13 pin is set from Low to High, each time short-term pulse...
I am using local buffer of large size (60KB). The address assigning to this local variable is of global variable. So my program is not working properly. I had implemented TFTP using LWIP. So how LWIP is utilizing SRAM is not understandable. If anyo...
Hello,So we are building a ball shooting robot which self detects the speed the ball was launched. The average speed is in range of 80mph. To get speed we are using two light gates, one on PF9 and one on PF10. So I set up EXTI interrupts on these two...
Hi,I'm using STM32CubeMx to generate UART initialisation code for STM32H743 controller. I'm able to test UART communication for baud rate 3686400. I'm not able to make UART communication up & running when I changed baud rate to 4000000.Is there other...
Hello,My question is that how many interrupts could be in pending state in STM32F1 MCUs? What would happen when a interrupt is running and in the same time another interrupt with same preempt priority be fired, does the running interrupt finishes and...
I am currently using an STM32L475VCT in my board design, and I also have an STM32L476G-EVAL board.I have ADC1 set up for sampling 6 channels continuously. Each conversion is triggered by an output from timer 1, I am also using 4x oversampling. The ti...
Dear all,In my system, STM32L412 is between MCU_B and Dev_S. The role of the STM32L412 is a bit like I2C bridge.That means MCU_B does any I2C read/write command from/to Dev_S must by the help of STM32L412.It is simple for STM32L412 receives I2C write...
Why would an ADC sample in 8-bit mode when DMA is used, but when used without DMA the full 12-bit conversion is retrieved?STM32F411 I am trying to set up an example project for ADC with DMA using HAL library.I am sampling a slow ramp function from 0-...
