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...
Hello,Nobody at STM seems willing to answer my questions to the NUCLEO-H7S3L8 board. I've two of those boards and spend much time with them, but nothing will work. None of the examples from STM32CubeIDE can produce any results with those boards.I wro...
Hi, My test board can enter sleep mode OK, but doesn't wake up when PC13 goes high: (never reach __enable_irq()) void Sleep() { __disable_irq(); SysTick->CTRL = 0; // Enable WKUP4 (PC13) PWR->WKUPEPR = PWR_WKUPEPR_WKUPEN4; // Enable WKUP4 PWR->WKU...
I have a bit of code as follows:str r3, [r0, #68]ldr r3, [r0, #68]where [r0, #68] is TIM20.BDTR on a STM32G474. I would expect that the LDR would output the same data that was just stored, however it seems that out outputs the previous data. I al...
I have STM32 Nucleo-G0B1RE Development Board. In our application we require OSDP protocol interafce. So that's why we purchase HID SIGNO 20 Reader. Now I want to implement OSDP via RS485. So, How i implement OSDP in the STM controller. Can you please...
Hi.I have a project that involves using an STM32U535 to control the LEDs shown in the picture.I feel it should be possible to control the COL-x signals with synchronized timers that also trigger DMA transfers to control the ROW-y signals, but I can't...
MPU:STM32H755XI6Connection with PC:USART1RTOS:ZephyrIn order to install Zephyr into STM32H755XIH6, if you build and burn images for M4 and M7, the M4 side will start but the M7 side will not.The content is LED flashing of PG10 (A9pin). Are there any ...
Previous post: https://community.st.com/t5/stm32-mcus-embedded-software/dma-on-stm32l011f4/td-p/742092 I am working with code on the STM32L011 that uses DMA to read data from USART2. I received excellent help on this forum before and I'm hoping fo...
Good morning, I am trying to print a string on STM32F401RBT6 using vs code and Cmake, but I keep getting an issue, when I use '\n' the UART doesn't print nothing beyond the '\n', can somebody help me with this issue, please? printf("Hello\n World");
Hi, The reference manual says - "In differential input mode, the analog voltage to be converted for channel “i” is the differencebetween the external voltage VINP[i] (positive input) and VINN[i] (negative input". "In single-ended input mode...
Hi,I am learning and exploring the STM32F756VGH6. My goal is to setup a simple UART and send some data to the PC using USB-UART serial converter and puTTy terminal on PC. I am using register based coding approach as it makes the code more efficient....
