lan8720 soft reset problem
Hi,I have a lan8720 phy board and I use this board with stm32h7 .I didn't change lan8742 source and header codes .Lan8720 board isn't make soft reset .

Resolved! STM32F107 I2C SCL stays low
Hello, I'm working on a project, where the Master (STM32F107) have to communicate with a few slaves (ATxmega) via I2C. Most of the time it works fine. But sometimes the SCL line is going low and stays low. First i thought it's a Slave issue (because ...
How to fill unused memory locations with RESET opcode or specific pattern?
I've developed a safety critical application over STM32F103RG microcontroller.I want to add a fail-safe mechanism to it by making sure that all unused memory locations are either carrying opcode to RESET (like available in PICmicros) or any specific ...
48MHz clock source selection, not necessarily 48MHz?
I have (another) dumb question... but I learn so much from my dumb questions, so bear with me.On our STM32F7, we are using a couple of peripherals that use the PLL48CLK. I see from [RM0410, Figure 13 page 153/1954] that this is selectable as the out...
Resolved! How to jump to another execution region defined by a scatter file?
Posted on July 19, 2017 at 17:58 I have successfully built a firmware upgrade app using C# and the bootloader in the STM32F4 To make it more robust, I am adding a scatter file based on CliveOne's recommendation: I'd generally recommend having a b...
garbage value with sprintf
hi everyone,Can someone tell me if sprintf is ok in Keil? Tera term prints garbage value.2 days ago I tried sprintf and it didn't work, I tried a simple declaration of a string and it worked.what's the problem?
Problem configuring DMA on STM32F130rb trying to read a temp sensor
Hi all,I'm trying to write a small program that will read the values from the temperature/humidity sensor. I will try to explain in detail what I have at the moment, but bear with me, I'm still a beginner in bare metal development.I am using an STM32...
Hello, I am working on the stm32f373C8T6 MCU and trying to get some values out of the SDADC but I don't get any values apart from 0 and sometimes 5209/5217 for some reason. I am following the datasheet's instructions that I will display below.
Initialization 1. As prerequisite, fill in the HAL_SDADC_MspInit() : Enable SDADCx clock interface with __SDADCx_CLK_ENABLE(). Configure SDADCx clock divider with HAL_RCCEx_PeriphCLKConfig. Enable power on SDADC with HAL_PWREx_EnableSDADC(). Enable ...
STM32F446RE ADC Tripple injected simultaneous mode triggerd by Timer 1
Hello,i want to use the STM32F446RE MC to controll a PMSM. For that reason I need to measure 2-3 currents simultaneously.I'm working with CubeMX used for the initialization and Keil for the further programming.Also i am mainly using the HAL functions...
Can I operate SD card on STM32F030F4P6 via SPI interface ?
Someone have suggest ?
