Hello,Greetings to all community members, This post is regarding USB enumeration in STM32H7 series. I am currently using MCU STM32H747XIH6 for one my project in which I am configuring this MCU in USB Host by using USB_OTG feature available in it. I a...
Hi everyone,As commented in the title, in our system we have two ways of working. At low speed (120MHz) and at high speed (480MHz). When reading the ADC3 (temperature sensor) depending on the mode (low or high speed) I get different values. When I wo...
When using the STM32H750VBT6, I supplied around 1.37-1.4 supply voltage to the external pins VCAP1 and VCAP2,the project was configured as an external power supply using cubemx software.HAL_PWREx_ConfigSupply(PWR_EXTERNAL_SOURCE_SUPPLY); is used in t...
Hi, I am using the B-U585I-IOT20A Board and I want the board to notify me in some way if someone is attempting to access and modify its content via JTAG. Is there a way to do this?
I designed a circuit board with the STM32f765vgt6 chip following ST's hardware recommendations (two 2.2uF ceramic capacitors with low ESR connected to Vcap1, Vcap2).I'm having the following issues: When I initialize the CPU clock frequency to 216MHz,...
Hello,I'm managing a Wifi modem using one of the USARTs of the STM32L475.Modem is working fine when sending and receiving AT commands and data, but I'm not able to receive URC's.I only receive URC's when they come 'together' (very close) to the answe...
Hello.I am trying to save variables to flash when there is power loss that i detect using PVD. I got PVD to work correctly and trigger interrupt at 2.9V, but now i cannot find the right examples to see how to save the variables quickly to flash. I h...
Hi,I am migrating my project from STM32F778AI to STM32H747XI and I have some issues regrading EXTI interrupt on M4 core.I use custom board with J-link programmer.I have simple button with hardware pull-up and I configured pin to be EXTI11 on M4 (enab...
HiI use STM32U5 SPI2 in Salve mode to only receive data，and the data-size is 16Bit. Because the rate is very fast, I use the DMA_LINKEDLIST_CIRCULAR mode combined with the DMA half-full interrupt solution.When I used HAL_SPI_Receive_DMA() to start SP...
I'm writing firmware for stm32c011f4u6 using Keil5. I downloaded and checked an example about ADC from the homepage, but I only found the code that uses DMA. Is there any example of using ADC with Polling instead of DMA? Also, I need an example for m...
