Hello. I try to calculate some pulses by wakeups from shutdown mode. I have 2 pins which areWKUP1, WKUP4. They are configured to wake up by rising edge. But sometimes when only 1 of them is rising, I receive 2 notifications, from both pins.The proble...
I'm working on a project for a battery charger and for safety purposes I want the complementary outputs of the HRTIM to be disabled when the core is halted. On the STM32F334, setting the HRTIM_STOP bit in the DBGMCU register resulted in both the HRTI...
Hi all,I working on parallel synchronous transmission. I am using LPTIM2 as clock (PWM) and GPIOE as data bus. It is working with BDMA but here is 50ns offset between Clock and data no matter what frequency I setup. Please see pictures below 84kHz a...
Hello, We have been trying to read 12 bytes of data on EC25 from stm32 controller.On the first run, data is transmitted by stm32 in slave trasmit mode and EC25 is reading the data correctly. We are able to capture the read log on EC25[Master read mod...
We are using STM32F4079I-EVAL board and are new to it. We have checked the examples and demo apps in --> STM32Cube_FW_F4_V1.24.0 But unable to find anything that could help us to print logs.
I use 2 board for generate pulse and count pulse.I generate pulses with 4Hz frequency by first board and print number of each pulse also when I press button pulse production stops and then after 20ms products a another pulse(I things micro in second ...
Hi,In stm32f051, iwdg is not working, I think.After enable iwdg, encounter the while(1); loop , reset is not issued.NRST pin is connected to RC reset circuit.BRPaul
In SPIx_I2SPR, I2SDIV=1 is probably fine as long as ODD is kept 0.https://community.st.com/s/question/0D50X00009XkYmHSAV/f2f4-i2s-extclockThis constraint probably unnecessary puts pressure onto using higher than necessary I2S clock, and restricts cer...
In the single-port DMA, CCR.EN when set, it locks most of the registers, including all other fields of the CCR register itself.Moreover, EN is not autocleared when single-transfer is complete. This is not documented clearly anywhere.These two things ...
I'm struggling to understand why I'm seeing a huge performance hit by slightly changing code in a loop. I narrowed down the problem to a manageable code size, and I'm hoping someone here can suggest how to investigate and resolve my issue.I'm using a...
