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...
Hi, the device have some kind of limitation on the usage of DMA?What I did:1 - Implemented DMA0 stream 0 and 1 to do the following:DMA0 stream 0 - Update the TMR2 ARR when TMR2overflow. Generate an Event on DMA transfer.DMA0 stream 1 - Sync with the ...
In our application we are using part no STM32G0KCIU6 of LQFP32 / UFQFPN32 - GP package.in application we are using USB communication there by we also required 16Mhz HSE, but in this package Pin No 2 of MCU has additional options to configure as OSC_I...
I have an STM32F103VET6 with multiple DMA Channels like UART2_RX, ADC, UART3_RX, UART3_TX, all at different priorities. The first one or two bytes of every DMA Channel becomes incorrect all of a sudden in runtime and corrects back only after power re...
Hello, We are using STM32H573AII3Q in our application. One external IC is interfaced with this uC through SPI lines. We are observing a tristate on MISO line. To investigate we isolated the uC and checked the MISO line. It is having a voltage level ...
Good morning. I'm running an STM32F767Zi on a custom board, LwIP 2.1.2, no OS. The device acts as a HTTP server. I've got an issue where I get GET requests and [FIN, ACK] packets retransmitted by the web browser.192.168.5.106 - Client192.168.5.196 - ...
Hello I'm developing RTOS environment of dual-core in STM32H757.In OpenAMP communication mode, CM4 is the master and CM7 is the slave, and I used SRAM4 to create SHMEM.I could refer to the examples provided by STM32, and I read the application note A...
Hello Error Definition1 : the return value of the OPENAMP_send function is 4. // RPMSG_ERR_NO_MEM?Error Definition2 : the return value of the OPENAMP_send function is -2007. // RPMSG_ERR_ADDR I'm developing RTOS environment of dual-core in STM32H757....
I use the internal RTC with MCU P/N:STM32U575.The schematic has two power supplies,RTC uses the VBAT power supply, others use the main power supply.My problem is that the RTC can count time normally, but when the main power is powered off and VBAT is...
Hi,I'm developing a custom bootloader.My freertos appl. is running well on debug mode in stm32cubeide while my freertos appl is on 0x08008000.MEMORY{RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K - 8/*FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 512K*/F...
Hi,I am trying to create a reliable communication in a noisy environment using RS-485 between 2 STM32 boards, one with STM32F302 that is receiving data from several sensors, performs some calculations and then send the data to a STM32H723 Board. On b...
