STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I'm trying to set the QUADSPI FIFO threshold when reading from external flash using interrupts and I want an interrupt to occur when there are 32 valid bytes in the FIFO. I'm setting the QUADSPI_CR_FTHRES to 31 according to the datasheet but when I l...
Hi all! I have been using a F446RE board to communicate with an encoder using SPI. I get back a 16-bit value every ms (the process runs at 1kHz). However, I now need to transfer the acquired data over ethernet (it has to be ethernet, not UART or anot...
This is regarding the UART1 and UART2. 1. I am trying to learn how UART works by communicating between STM32 and ESP32. I am able to send data from STM32 to ESP32 and it works. However, when I do the same from ESP32 to STM32, for some reason I cannot...
Hello,I am running the code as shown in the attached file and I get two different behaviours on to identical stm32h735g-dk boards. One of the boards will send exactly 37 can messages when the button for master is clicked and the other board will send...
Hello,I am trying to route printf-like data streamed from the SWO pin of an STM32L432KB MCU to a Windows command prompt using a STLINK-V3SET/MINI probe. I need to do this while flashing new firmware or debugging. The SWO pin uses UART encoding at 2 M...
Hi ST tesam,When I use the HAL of STM32C031, I have some trouble about SMBus.Q1:When I use the SMBus of STM32C031 series. If I do not got the feedback from the slave, sometimes the SDA will pull down(similar to the yellow line show as below) and syst...
Hi Team, where we are trying interface ENC28J60 in STM32F407VG Microcontroller to use Ethernet, Is there any procedure to create a project in cube ide are any link related to this board how to interface ENC28J60 to STM controller. Best Regards,Gagan ...
Working on a product-based STM32F203, getting multiple ARM exceptions of all kinds, Bus Fault, Usage Fault, Hard fault, and Mem fault. The issue is I have a year-old debug Log for debugging purposes. I can't recreate any ARM exception to check the st...
I want to connect 2 Nucleo F103RB as slave (2 Nucleo slaves) to one master (PC for now) over Modbus (RS485). how can I do that? Please note I am new to STM32, so I have limited knowledge.P.S. I have connected one master (PC) and one slave (Nucleo) bu...
Hi team,I am currently developing a board with the STM32L476RET6. This project involves UART communication (UART4, PA0 and PA1), and I am concerned about EMI due to the fast rising and falling edges of the TX signal. To address this issue, I am imple...
