Hello, I am attempting to have a two stm32 nucleo boards communicate by sending and receiving can messages. My goal is to have the PA5 LED of the STM32 f446re blink when a can message is received. I know that the canbus must be configured to classic...
Hi,in a setup on STM32H725 where TIM1 ETR triggers several DMA activities, I observe an effect while debugging that I would rather like to avoid:Looking at the NDTR of the three DMA, it seems that one extra ADC run (or at least the related DMA transf...
Hello everyone,I'm currently using the STM32F401CCU6 in my project, but it's proving to be oversized for my application, both in terms of physical package and power requirements. I'm hoping to switch to a smaller STM32 microcontroller that maintains ...
Hi all,I am trying to activate SDADC on my custom designed board to measure a couple of analog voltages. I am trying to measure 5-channels in injected continuous mode. Offset = 0, Gain = 1, Single-Ended Offset Mode. See the CUBE settings below :In th...
Hello!This is the first time im using NOR Flash so bear with me :)Question #1I screwed up and forgot to add a pullup for the open drain ready/busy NOR output.So i've tried the ghetto approach of using the internal pullup of the STM32 as "busy wait" b...
Background: F429 works as a net node in the ethernet switch. Other nodes are cortex-A or CPU, so the controller with F429 has the poorest capacity for processing net data flow.Current Implementation: As the controller only exchanges data with a speci...
How to output CLK for receive-only (master) in SPI communicationWe want to create a receive-only (master) in SPI communication.However, SPI_CLK is not generated.In the case of a transmit-only (master), I think that CLK will be generated if CLK is ena...
Trying to write a i2c driver for the stm32f0 and having trouble understanding how this works as im use to the stm32f4 i2c could anyone describe what steps i need to take to write a polling i2c driver or point me to an app note that describes ive ben ...
I checked with the Uploaded File schematic board. I'm using STM32CubeProgrammer. Connect from PC via UART. I confirmed that the UART is connected with STM32CubeProgrammer. Software has not been written yet. In that state, the MCU became so hot that...
Hi I am using X-CUBE-DPOWER to set the parameters for my Buck converter operating conditions on a B-G474E-DPOW1 evaluation board. I am trying to understand how the controller is implemented. For the PWM switching frequency, I know that this is done b...
