TIM5 problem with STM32F469I

I am using 32bit TIM5 in an STM32F469I. I enable the timer and divide the 8M clock by 1000000 to get microseconds. I then use microseconds to time pulses coming into the board from external device. All works well until the timer overloads. I can ...

Crystal drive level for STM32F030

Hello, I am trying to select a crystal for a design but I am having some difficulty. The data sheet provides little information and AN2867, too much but not very useful IMO. AN2867 depends on taking measurements to determine DL and I do not have the ...

NUCLEO F303RE Analog reading spikes or noise. CubeMX Question.

Hi,Code mostly generated by CUbeMx, small config changes. I see spikes comming into ADC value. The termistor is between 10K and 5.6K. I took it an used a voltage generator, same reading with spikes. Same reading on NUCLEO dev board, same on a custom ...

Regarding custom bootloader for STM32f412g-discovery board which can support USB DFU class

I have a requirement for implementing firmware upgrade feature for one of our products which is based on STM32F412ZG microcontroller. I know that ST provides a system memory bootloader which already supports firmware upgrade using USB DFU class. But ...

How can I get a program to run standalone on a Nucleo L053R8 board?

I can build and run a program fine through IAR, but this board will not run when powered from a PC without using the IAR debugger. I assume this has something to do with the bootloader.

Can the external SDRAM address 0xD0000000 be changed ?

Hi, thereI am studying the sample codes : STM32F429I_Discovery_FMC_SDRAM and was wondering if the starting address of the SDRAM 0xD0000000 can be changed to something else. I don't see SDRAM memory section in the linker file and don't find any SDRAM ...
