I think I may have found a bug with the STM32G4 RTC that I am not seeing in the errata.I am using the RTC on STM32G4 with a 32.768 KHz LSE oscillator. I am having a issue where I would read the RTC twice fairly close together in code. I observed that...
Hello, i am interested in the input structure of the NRST pin of the STM32G0x0 series. The datasheet shows a reduced diagram. My question is: is there a more detailed version of the input structure. Is a clamping diode to Vcc build in? If so, which ...
Hi everyone,I'm using the STM32F407 for CAN Communication with the Loopback Mode. I'm trying to send a cyclic frame using a timer.I'm using the timer2 with a clock of 84MHz (APB1), a prescaler of 8399 so i will have a tick every 1ms and a period of 1...
Posted on February 28, 2017 at 12:35Im using STM32F103C8T6 and have issues with RTC and VBAT. Project generated in CubeMX 4.19.0 for Keil, I commented date and time setup in MX_RTC_Init() and time restores fine after reset/power off, but date become...
Hi all,I'm quite a beginner with these kind of memories. It seems that the ST Core Coupled Memory is inspired in the ARM's Tightly coupled memory concept, however, do they have a significant difference? Perhaps a special Hardware adapation to ST's Mi...
Hello, I am writing USB OTG from scratch for a Nucleo-f439zi. Till now I have managed to make it reply to some Setup requests, to be more specific it replies to Device Descriptor and set Address , ( I am currently figuring out Configuration request w...
During the user-defined BL upgrade process of the STM32, is it possible to keep an IO pin, which has already been pulled high in the user code, at a high level throughout the entire sequence of steps: 'jumping from the user code to the BL, erasing an...
I am interfacing many 5.2VDC signals with an STM32F103VET6 MCU, using PB0,PB11,PD9,PD10,PD11,PD12,PD14 as input. According to the datasheet these pins are 5V Tolerant. In the past, regardless of a pin's "tolerance" to 5V I have always used a level sh...
Hi,I'm working on a custom module based on a STM32L452CCU MCU.I'm reading the temperature of the MCU (using ADC1 with DMA, temp is updated at 30Hz using a timer)When I read the ADC value on a regular basis while heating the MCU, I can read a voltage ...
Hello everyone,I am working with a custom board featuring the STM32H7B0VBT6 microcontroller, which has only 128 KB of internal Flash memory. This is insufficient for my application, so during the board design phase, I included a W28Q128 external Flas...
