Hello I need to send a string via USART every 500ms. I tried to use DMA that seems to be easy to configure. USART transfer works but only without DMA (test in while main cycle). I do not see any problem in DMA configuration. Can you tell me it there ...
Hi , I tested example " I3C_Controller_Private_Command_IT " with Controller H503RB board and modified for JEDEC SMBUS for DDR5 ( JEDEC smbus is more simple than MIPI I3C ,No DynAddrAssign function , Initially I2C after CCC SetAASA , it ...
Greetings Everybody, I have Nucleo - F207ZG board. I have attached external 3.0 V coin battery to VBat and GND. I am configuring board for RTC peripheral. After configuring RTC time and again rechecking after 1 day the time starts to move ahead or ti...
I am using two quadrature encoders through the STM32F411CEU6 timer encoder mode. Here is the graph for one of their CNT values:As you can see, it takes about 400ms to update the value, but when it does, it seems accurate. How can I make it so that it...
Posted on April 26, 2018 at 09:34Hello all. My problem is as follows.I would like to set an event in the future, lets say 950ms, at one specific point in the code. Then I would like to set the STM32L432 in Stop2 mode, wake up the MCU near the event,...
Hello guys !I am new at the embedded systems and I am trying figure it out ! I am using STM32F446VET7.I connected my buzzer to an GPIO pin(PB12) which has no pwm speciliaties.But my buzzer is not working when I connected to the DC signal source like ...
HiI'm trying to working on Enabling the TCP Server on STM32 NUCLEO-F767ZI using the LWIP stack and RAW APII am able to ping to the board & also connect to it. However, when I send a text data from Hercules say "123" then I receive "123". However, acc...
I used STM32F446VET7 on the board I PCB printed. When I use HSI, I can debug without any problem, but when I want to use HSE, SystemClock_Config(); function enters ErrorHandler().Can you help me?
I can not find any instruction in documents about gpio configuration in alternate function mode. For example I want to configure SPI GPIO. Examples found in the internet have different configuration. Is it unimportant to configure push pull and pull ...
Dear Stm32 users,I currently plan to design an analog function generator and capture System.The old System used an analog lock in amplifier circuit to excite and capture noisy signals from a measurement source.For cost and pcb size saving i am consid...
