How to get interrupt after specified number of microseconds?
My idea was simple. Set TIM to have 1MHz after prescaler. Then set ARR to the number of microseconds. So - I toggle GPIO pin each period elapsed and I can measure the time on oscilloscope.And here come troubles: for set 1us i get 2us. For 2us I get 2...
Resolved! STM32L062 hard fault with timer enabled
I am using Segger Embedded Studio 6.32 to develop a project for the STM32L062K8U6. While there are some start-up files created by the SES project wizard, I am not using any pre-built libraries and developing all my own code based on information from...
Switch comparator input
Hello, I made a an esc using an arduino a year ago and I wanted to try it with my stm32L476RG, for some reason my code doesn't seem to work, and I think that I'm doing the switching of the comparator input minus wrong, can you tell me if this is the ...
Resolved! Hello i have a problem with FLASH SR REG setting up flags when i try to write in flash, im using stm32g4 wit 521kbs flash and dual banks plss help.
Here is my code : ignore the led toggles , the screenshot of the sr reg is below and highlited bits. Im guessing it has something to to with the arhitecture of the cpu.Kind regards.void flash_page_write(void){ uint32_t addrr_start=0x08001000; uint3...
Question of dac output frequency
Hi,Recently I used STM32F407 to develop firmvare code of external DAC device.In order to obtain a sinewave output from dac, I choose TIM2 to trigger interrupt.TIM2_period is configured as 167, and TIM2_prescaler is configured as 0. The sysclk is 168M...
Resolved! Comparator trigger mode register
Hello I have a Nucleo board L476RG and I would like to change the trigger mode of the comparator on the fly, the problem is that I cannot find the register responsible of this in the datasheet.I guess it's not related to the comparator but to the EXT...
I'm using STM32u575ZI-Q Hardfault is triggering in debug mode when it hits a breakpoint. I'm facing this on implementing IWDG. May I know what might be the issue and resolution?
Here is my code for IWDGLL_IWDG_EnableWriteAccess(IWDG); // Set the prescaler value of 8 to the IWDG LL_IWDG_SetPrescaler(IWDG, LL_IWDG_PRESCALER_8); // Specify the IWDG down-counter reload value LL_IWDG_SetReloadCounter(IWDG, 2000); ...
Resolved! Bypass vs Crystal ceramic
Posted on July 04, 2017 at 15:47Hello Team,As per STM32F769I-DISCO board schematic, I understood it should be Bypass clock source.But default cube project gives selection as Crystal ceramic. Why it is ceramic crystal?Request you to help me which one...
