Hi,Can anyone explain how DE/RDY lines are working in different directions? I am getting confused while reading the Ref manual. The RM0468 states in Table 305 the PSSI_DE is an Input which serves as " Data enable signal: data valid signal when receiv...
Dear, My customer is looking for the STM32 MCU that can connect to wifi without using an antenna, has more than 33 GPIO (Digital Output) but not too many outputs and can operate stably in an industrial environment.Please advise the possible product. ...
hello friends!Now a days i started working on TouchGFX for Waveshare's OpenH7XXI-C board and CoreH7XXI MCU. I interfaced 7 inch display, FMC SDRAM as bank 2 and W25Q128 QSPI. after configuring these peripherals i tested them manually by writing and r...
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 everyone,I’m currently facing an issue related to bootloaders and FreeRTOS on STM32 microcontrollers, specifically the STM32H735 and STM32H730.Here’s the background:STM32H735 Development Board: I have successfully implemented a bootloader that jum...
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...
