How to use the master Hi-res Timer as a prescaler for the slave Hi-res Timers?
I have an H7 application where I need the HRTIM master (or another timer if that is the only option) to be the prescaler for HRTIM A~E timers. How do I do this?

I would like to hold the STM32H745 in reset and then connect with JTAG and be able to reprogram the flash internally. I am finding that their is some setting that is damaging a part on boot up and want to prevent the device from booting but still be...
STM32 H757 QSPI read not working properly.
Board: STM32 H757Issue: We are using internal QSPI memory. Write is working fine. But reading have issue.reading ignores first byte and also do swapping of 2 byte.For example: --> write 0<offset> 4<number of byte> 1 2 3 4<values to write>--> read 0<...
Resolved! Problem Running ADC with DMA in single-shot mode
Hello,I'm trying to capture single-shot ADC reading from 3 subsequent channels. I'm using CubeIDE and STM32L100RCT6 on the Discovery board, but I have the same results with STM32F103CBT6. I do everything according to that document, but whenever I try...
Interfacing with I2C does not work in STM32F100xx Value line Discovery?Please help
Hi all,I want to use the I2C of my STM32F100xx Low/Medium density value line Discovery board but without using STM32cube IDE because i want to learn the basic register initialization and each step necessary so that i can port it to any IDE but i am u...
Resolved! Issue related to migrating from Keil MDK to Atollic TrueSTUDIO. Are my settings correct?
Hi all,I asked a question about settings 3 days ago, but there was no response from the community. However, I fixed the problem myself. I am sharing the solution as it may be useful for those who want to migrate the project from Keil to Atollic in th...
Can I interface 10 SRAMs using FMC controller and external address decoder for generating chip select signals.
I need to interface 10 SRAMs (1024 x 16). With existing FMC controller I can interface only 4 so I am planning to use address line decoder for generating chip select signals. My main concern is whether I would need to use external buffers & transceiv...
SDRAM Chip Select & Clock Enable connections in STM32H750
Hi team,We are using STM32H750 MCU in our design. We are interfacing an SDRAM memory to the MCU using FMC. But we have doubt on the SDRAM chip select & clock enable signals. We are planning to use FMC_SDNE0 & FMC_SDCKE0. But In Discovery kit, FMC_SDN...
