Hello,Due to so attractive price + some specific features, the H7 Value Line looks to me very attractive to take into a new design, but 128kB Flash is not enough for me, I have to take an external flash, which is QSPI. I have a few basic questions a...
Hi! Wanted to know if i can use BOOT0 as GPIO input after my stm32f7 SW is up and running?
Hi,I am using PB0 and PB1 (no choice) alternatively but synchronized as PWM output and input/compare.For output, the only way to have two different DMA channels is to use a complementary output for one the two I/O.It seems a timer complementary outpu...
I'm currently using an STM32F4 board for a project that requires fast ADC conversion (2.4msps per channel, all 3 channels simultaneously) *and* pretty extensive cross correlation. Due to the clock tree of the F4, if I want to use the highest ADC cloc...
On an STM32F4, I am using a timer in IC mode using a DMA transfer. I'm able to do this by setting up and using HAL_TIM_IC_Start_DMA. For a given timer channel, the "DMA request mapping" table in the datasheet shows which stream is connected to which ...
CubeMX 5.1.0, stm32F303re, OPAMP4 dropdown box Follower-DAC_OUT1_INP. Code section: hopamp4.Init.NonInvertingInput = OPAMP_NONINVERTINGINPUT_IO3; is not correct, should be: hopamp4.Init.NonInvertingInput = OPAMP_NONINVERTINGINPUT_IO2;reference to ...
I'm writing an application for a STM32F407 that requires very high speed ADC for 6 channels (two for each ADC, using regular simultaneous scanned mode), then once a series of conditions are met, perform quite a few cross correlation calculations for...
Dear Member,I tested my GPS module with moving car,I can not see any result, but when the car stopped, I saw the result,I can not see the speed as well on GPS.GPVTG.kph, any same experiences ?Any ideas on how to fix it ?Thanks
Dear Members,Is it possible that I share SPI2 for SDcard and LCD ?thanks
Hello there,I was wondering either it is possible (with STM32L4) to turn on a PWM channel for a certain amount of cycles or for a certain amount of time? Ideally, without any interrupts during this period or at the end.I am trying to figure out a way...
