i have a problem with Readout Protection in the STM32F4 MCUs. If i set in the readout protection level 1 in the software, than works mcu to some times, but after some power reset it stops. It runs no longer. What i could do is that i set the option b...
I am working with the Iot Node Kit and Azure. I've found that after running for > 12 hours it stops sending messages to Azure so I'm trying to track that down.One of the modifications I made to the demo code is to create many functions that serializ...
The datasheet values for RAIN max are somewhat onerous, as I would need to buffer pretty much all my ADC inputs to support decently fast sampling. But they don't seem to fit with the equation suggested by the design guides. Is there something about t...
Hi,Could you please let me know the default state(Pull up /Pull down) of GPIOs in STM32F427VGT6. Especially I need to know the default state of GPIOs PC4, PB10, PA7 inorder to verify the strapping options for an external Ethernet phy interface. Iam i...
Hello,I am trying to drive a piezo with complementary output from a timer. I am using TIM8_CH2 and TIM8_CH2 as control logic for my piezo command. I expect it to be complementary to increase volume of the piezo. TIM8 is configured as slave of TIM2 th...
I remember seeing a flowchart showing the order in which interfaces are checked for activity during programming when the BOOT pin is pulled, but I have been through the datasheet, programming manual and Google and can't find it now. Can anybody poin...
In 15.5.12, the register definition for mdma_ctbr , i am having trouble understanding the dbus and sbus bit descriptions. Shouldn't the choices be between tcm/axi and ahb/system and not system/axi and ahb/tcm as the latter is mixing the domains toget...
Hi,I have some problems with UART4 on STM32H750. Uart4 is asynchronous RS485 mode mapped on PC11,PC10 and PA15 (DE).I tried to SWAP RX/TX without succeed. Finally, I swapped it by wire.DMA not working properly. DMA Counter works. Memory address neve...
Hello,in my project I connected 6 channels to ADC3; then i set up:A single mode regular sequence to read 5 of them using DMA; start of sequence is given by software inside a periodic task An injected sequence for the 6th channel to trigger a conversi...
