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-...
I tried to test the main while loop frequency with short code that throw the HAL_GetTick() through uart (baudrate of 115200) and present it every 18000000 (18M) main while loops, I also measured the time between each loop and I got the same value of...

I was able to get this working for the L5 with one large circular buffer and interleaved values from the ADC channels 1-4.Given the improved DMA on the U5, I expect that the DMA will not have to generate an interleaved circular buffer of ADC channel ...
