D flip-flop
Hi,I need to normalize the asynchronous transmission to a specific baudrate in real time. I know flip-flop D is fine, but I don't want to add extra elements to the layout. Can I do it with timers or maybe some other solution?

STM32F429 Sleep mode and Systick
Hi'I'm using an STM32F429 in a project that needs to enter to sleep mode.I can't determine if I need to disable manually the HAL tick previously to entering in sleep mode, or if the sleep mode enter instruction does it by itself. Can anyone tell me?T...
How do you set the output pin low after timer's one time pulse?
I have timer8's one-time-pulse working however when the CNT reaches ARR and is set back to 0, the output pin goes high again. ( since CNT < CCR1 )How do I ensure the output pins remains low after the one time pulse?
Resolved! STM32H745: VMA does not match actual memory address for a given variable
In my application I am using initialized data in shared memory for the use in a user interface. The memory is in the SRAM2 at 0x30020000. Both cores need to access that same data.This code is placed in the Common directory so that it is picked up dur...
How to send a remote data request in CAN-FD
Hello,I am working on CAN-FD project and and I am able transmit and receive data. Currently it is continuously sending and receiving the data. But I want to send data only when receiver sends data requests. How can I do that? thanks for help
Resolved! How to properly initialize shared arrays on STM32745?
In my application I am using initialized data in shared memory for the use in a user interface. The memory is in the SRAM2 at 0x30020000. Both cores need to access that data, so I use code of the following form:__attribute__((section(".sram2"))) uiSe...
Resolved! My kingdom for some samples! (STM32L4 + LQFP48 + DFSDM)
Yes, I have tried contacting the local ST sales reps here in Australia - no response.Sorry, I've resisted asking this question for a fair while because I know many have greater need. But I thought I would ask this question just in case there is a sec...
Resolved! I'm currently integrating a Micron MT29F1G01ABAFDWB NAND flash with a STM32L4R5ZIT using its OctoSPI peripheral. According to Table 119 on page 556 of the SMT32l4+ reference manual RM0432, Micron mode is not supported. Which OSPI modes does this include?
I'm currently trying to integrate a Micron MT29F1G01ABAFDWB NAND flash with a STM32L4R5ZIT using its OctoSPI peripheral. A colleague of mine found Table 119 on page 556 of the SMT32l4+ reference manual RM0432 that seems to indicate that our MCU does ...
How to start STM32F767ZI Nucleo board when connected to an external 5 VDC power supply ? I set JP3 to E5V, when I switch on the 5 VDC external power, green led LD6 PWR goes on but I have to press the reset button B2 to start the program running.
Not clear if I have to remove SB111 (only if powered with 3.3 VDC according manual)So, how to make the board running its program without user intervention when it is powered via E5V (pin 6 and 8 of CN11)Thank you, J.
