SRAM turn around delay
hi,i am using STM32H743BIT6 and SRAM IS62WV51216EBLL-55TLI.i want to calculate the SRAM turn around delay or TAT (Turn Around Time)?
STM32L162 FLASH and EEPROM migrating from STM32L1xx_StdPeriph_Driver
I am restoring the programming of an old project on STM32L162ZDT which was using STM32L1xx_StdPeriph_Driver. Switching to STM32CubeL1 LL library (not HAL) gives me problems with FLASH and EEPROM support. Is there any tutorial on how to get through?
Resolved! Failed attempt on using 2 Timers to Toggle GPIO.
Hello , I have initialized two timers , Timer3 and Timer9. Im using Timer9 with 137uS period , setting my gpio pin high , starting Tim3 Interrupt with 54uS period for now .When Tim3 Interrupt occurs I simply reset my gpio pin.My problem is that I sho...

Resolved! Does software "stm32 st-link utility" support programming Stm32H5 Series MCU?
We are trying to use software "STM32 st-link utility" to program stm32h563 series MCU.However, it could not recognize our target MCU and shows "no target connected".Stm32h563 Target not connectedThe SWD pin connections are correct, we are able to do ...
UART in Interrupt mode Stuck??
Hello all,I'm using STM32 F103CBT6 MCU on a custom board where MAXRS485 is used. Rx and Tx of the Modbus chip is connected to USART1 on the MCU.To receive and Transmit data I'm using UART in interrupt mode. The program also has 8 GPIO interrupts on m...
Resolved! Button not getting released after touching when using stem win library
I created a button widget with stem win library. The button click is detected but button release is not happening. I tried using some demo programs there it is working. I have attached a basic program which shows when a button is pressed and released...
Resolved! ADC Conversion time and Sampling time
I have an stm32f407g.In the reference manual (in the ADC section) I found several terms I am afraid I have confused between them.I would like to explain my reasoning with an example and get your feedback if I said something wrong. -------------------...
