I've been programming microprocessors for over 40 years and the STM32F301K8 has me stumped.I'm required to use it in a low budget project with some unusual characteristics.I need a working example of:Using STM32CubeIDE and the target STM32F301K8 or S...
Hello, I am receiving data on my STM32F411E board via the I2C interface with the Mpu9255 IMU sensor. I get HAL_BUSY status in case of any power outage or re-debug.https://stackoverflow.com/questions/69912431/issue-in-the-i2c-communication-stm32-hal-l...
The product selection guide lists a lot of MPU and MCU devices but, I cant see an efficient way to form a logical AND of several attributes/features :(Eg I'd like to find within some max pin counts such as 16 or for that matter any way to cross refer...
Posted on June 06, 2018 at 08:02I try also to use SWO printf (SWV, SWO viewer in ST-Link-Utility). It is not working. I am aware of this thread: https://community.st.com/s/question/0D50X00009XkWZQSA3/no-traceswo-output-on-stm32h7xxBut I tried step-b...
The datasheet of STM32H723ZG claims to have a highest USART baudrate at 12.5Mbit/s (with 100MHz kernel frequency and 8 oversampling). But with voltage scaling 0 (VOS0), it is possible to have a higher kernel frequency to 137.5MHz, and therefore the b...
Hi I am trying to send some CAN-bus messages from a STM32H723VGT6 mounted on a BIGTREETECH SKR 3 EZ V1.0 I am following this video to send standard CAN messages in external loopback mode (https://www.youtube.com/watch?v=kXyzaaSk6Qs&t=568s&ab_channel...
Hello,currently I'm using stm32l496 in that i want to wake up the controller from the standby mode on an external interrupt.i configured pin PC13 (supports wake up functionality) as an external interrupt with rising edge , now when the MCU enters int...
Hello, I am doing a project with STM32F411RE NUCLEO board. I have downloaded the zip file from the web builder GRBLHAL. i have attached the file here. And I have successfully imported the zip folder onto the stm32cubeide. So for that project I want t...
I’ve created a SPI peripheral as a slave in transmit-only mode. It operates in circular mode DMA and generates a complete callback every 20 milliseconds. Upon receiving the complete callback, I want to modify the source address of the DMA request.Cur...
Hello everyone,I’m trying to activate the USB module present on my custom board equipped with the STM32G0B1ME microcontroller. Currently, I would like to see data transfer from a PC serial terminal to the microcontroller. Unfortunately, this is not ...
