We're developing for the STM32F767, primarily using the HAL. We have devices on the SPI bus which require different timing clock polarities. Re-configuring the SPI hardware through repeated calls to HAL_SPI_Init works, however, the actual hardwar...
Is it possible for any of the analog watchdogs of ADC1 to be used to trigger TIM8? I would like to stop a PWM generated using TIM8 when an ADC1 conversion crosses a threshold. Table 251, Interconnect to the tim_etr input multiplexer seems to indicate...
I am using UART to display the live readings of my DHT11 sensor similar to this blog post https://controllerstech.com/using-dht11-sensor-with-stm32/ and my program seems to stop around the DHT11_Read() or DHT11_Check_Response() functions. It seems t...
I followed the UART example (https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step3_Introduction_to_the_UART) and implemented it on a STM32F051 Discovery kit and on a STM32F446 Nucleo board with pretty much identical settings from CubeMX.If I scope ...
I made a custom board with an STM32F412RE chip and I can program it, and step through my code, but when I try to initialize my system clock I get stuck in a while loop that times out that I don't think should.[Here](https://imgur.com/a/Jqa1JmG) is my...
I'm converting the CubeMX usb audio device example to be audio class 2.0 compliant, with high-speed external phy.I have to implement a feedback endpoint to report the current number of samples per microframe. For this, I have tim2 set up as external ...
EDIT: Note change of direction of things in 3rd post.I have a stm32f091, which has a program that basically runs one mainloop that triggers ADC measurements and polling values from i2c chips using the i2c2 peripheral in master mode. ADC uses a DMA ir...
Hi everyone, I'm working with the MCU STM32F303 and the Reference manual says the following:So I'wondering if it would be possible to manage both interrupts separately with CAN_IT block. Currently with the block it seems that it's only possible to ge...
I'd like to start with that using the STM32CubeIDE and modify from there to get my own code to work. I looked in the example space and there are no code examples for the F3 series. Thank you for all pointers.
Small delays occur in projects and tests. The delays are usually about 6us. They also occur with simple calculations. What can be the reason? I have already tested with a new project without functionalities.
