Hi folks,recently, I started working with the STM32H755 dual core processor. With having 2 cores connected to the same peripherals, more opportunities and problems arise.Currently, I have a setup where I run FreeRtos on the M7 core and bare metal cod...
Hello, I need to make software triggered one pulse output for 300 ms. The question is what is the best way to do this? I have found that PWM can work in one-pulse mode, but it looks like it requires external trigger to start, which is not an option f...
STM32F413zhj6 bga package, customer has noticed strange behaviour on the IBIS model. When modelling output of K11 and K12 (PD14 ans PD15) the capacitance for the mdel is in the nF range. This is very large when compared to the other pins where they a...
Hello, this is my first project with stm mcu and my development board is on the way. I would like to make a hobby wav player and I have found a rather good recipe to start with - AN3126 Application note "Audio and waveform generation using the DAC i...
Hi guys, i need to ensure there is no swtich bounce for my STM32F4.Expect use the HAL_Delay is that any way that i able to debounce it?I will include my code at following:tenButton_State fnenRead_Pushbutton(void){ tenButton_State enButton_State; enBu...
Hello. I am testing my own board with STM32H743.As the title suggests, DMA needs to be enabled.If don't using DMA, you can write SD card normally.If use DMA Enable, f_open will wait 30 seconds (just like the timeout setting) and will fail with an Err...
hellocan i use STM32F479 DSI host interface to connect with Raspberry Pi camera ( this camera has the same interface ).regards.Zakaria
I looked in corresponding reference manual (RM0385 rev 8) but all it appears to give is an "example" tables on page 226, which does not match what STM32CubeMX 5.2.0 says.I also could not find in the stm32f32F745xx datasheet (DocID027590 rev 4). The ...
I am writing a C++ I2C driver that would operate as a SLAVE device operating under interrupt and without CLOCK STRETCHING using STM32H732zi nucleo board My problem is that the first byte that I tried to transmit seems to always be 0xFF no matter what...
According to the ST boot mode selection (page 236), we can activate the bootloader following the pattern: Boot0(pin) = 1 and Boot1(pin) = 0; but the DatasheetSTM32L0 doesn’t specify which one is the BOOT1 pin in the pin description (page 33). I could...
