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...
I'm trying to use a STM32 Nucleo-L476RG to get audio from a PDM MEMs Microphone (Infineon IM66D120A) using DFSDM and save the audio to an SD Card. I'm able to write to the SD card using SPI but I'm not able to get any usable audio recorded onto the S...
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...
