The errata sheet of the STM32F042 states:The time-triggered communication mode described in the reference manual is not supported. As a result, timestamp values are not available. The TTCM bit of the CAN_MCR register must be kept cleared (time-trigge...
Hello I'm using SPI to interface my STM32F7 with the SX1262 radio. I got a weird behavior, I'm using a GPIO to toggle the NSS pin. But sometimes it toggles randomly during the data transfer. You can see on the following screenshot of my logic analyze...
I would like to know what load capacitance to have the Processor and RTC crystalsmade by the vendor. Typically the crystals are precision ground with a load capacitance such that when operating in the circuit the frequency will be very close to what...
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...
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...
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 ...
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...
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...
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...
