Good electronical morning to everyone.Context:I find myself needing to enter stm32´s system bootloader during runtime on command.I asigned a GPIO with a simple RC circuit to pull the BOOT0 pin high.The system reset is done by IWDG exception, i just s...
I know jump to system bootloader using BOOT0 Pin, but my requirement is to jump from user application.I successfully jump to system bootloader from user application in STM32L100RC, but its not happening in STM32H743BIT6.Please support if any know how...
I have a problem with +500byte ICMP packet, I am using ubuntu 16.04 and firewall inactive. When I try to send ping with this command ping -s 500 192.168.1.127 ping is successfull, but when I try to send this ping -s 580 192.168.1.8 ping reply didnt a...
I can loop to see a bunch of alert status changes in the alert status registry(0x0B). My alert mask register(0x0C) value is 0x11. Also PD sniffer shows new PD negotiation successfully.Thanks.
Background of a problem:I am using ST low level libraries for USB OTG and USB HOST. I wrote my own USB class for ASIX USB-ETH adapter based on template and CDC class. The problem was that solution presented by ST driver was to slow. I could only send...
My APB1 Clock Frequency is 42Mhz.Init:hcan1.Instance = CAN1; hcan1.Init.TimeTriggeredMode = DISABLE; hcan1.Init.AutoBusOff = ENABLE; hcan1.Init.AutoWakeUp = DISABLE; hcan1.Init.AutoRetransmission = DISABLE; hcan1.Init.ReceiveFifoLocked = DISABLE; hca...
Hello,I have a PDM MEMS microphone that I am reading in I2S master receive mode. I am trying to take this data and put it in a FIFO buffer and then output the data over UART using DMA. I must be confusing the buffer sizes because I get mostly zeros...
I'm writting a very time-critical application for the STM32F334, where I have to control 4 power converters (mostly 3, one is time-shared another power converter). And recently I saw some ways to optimize code, like this://*********** 1360ns ********...
Hi everyone,How can I calculate cross power spectrum density by using cmsis dsp library with stm32f407 discovery board.
Hi all,I have a project for which we need as fast as possible drivers so we use as much as possible the LL drivers . Yet it seems that there was no implementation of LL for MDMA, even if it seems that all other DMA managers have theirs.Anyone knows w...
