I'm using an STM32H733 running from HSE clock with CSS disabled.In a normal situation, the used GPIO inputs correctly read as HIGH as they are pulled HIGH by an external pull-up / LVTTL (push-pull) drive, verified with the oscilloscope.After exposure...
Hi.. i'm stuck with this problem for days... i'm not able to store basic data in the G030 flash memory...When i tried to erase a flash page using HAL_FLASHEx_Erase(), the FLASH_WaitForLastOperation() returns a HAL_ERROR... I did not found the issue.....
Hello guys, I am building a product, actually am migrating my product from ATmega to STM MCUs, my requirements exactly are as follows,Cortex M0 or better core, >48 MHz2 Channel 5V DACs1 Channel CAN for OBD2 Interface2 Channel ADCs, at least 10 bit re...
Designing custom board based on STM32F746G-DISCO. I am using the TQFP chip, so a few less IO. The DISCO board uses a 4 wide data, but I do not have enough pins so I will only have 1 bit wide data. I only want to use SD card to be able to upload n...
@Tesla DeLorean Hi! I wonder if someone can help me! I am trying to initialize a LCD screen and I have some questions. I am using a STM32F469IIT6, and it does not have enough memory in itself to hold a buffer for my screen 800x480. I did not set up ...
Hello, As a newbie to STM32 , Could some experts please answer these questions for meIs there any basic documentation that provides an overview of what software i will be needing installed on the PC? This is what is my understanding so far, there is ...
Hello, according to the datasheet of stm32g051f8, the absolute max power supply voltage is 4V but the fully charged 1-cell LiPo battery Voltage is 4.2V. Can I power this MCU directly from the battery?
Hi everyone,I'm currently working on a BLDC motor control project using the STM32F103RB (Nucleo-F103RB) board. I have two questions regarding handling 5V logic signals with this MCU:I need to read 5V logic-level signals from a BLDC motor's Hall senso...
Hello,When I plug this board to my computer, appears a removable disk of 1,6 MB capacity.Is this disk accessible from the MCU? For store small data, or make a dataloggerWhere the filesystem is stored? Neither the STM32F446RE nor STM32F103CB of the ST...
Hello.I am testing QSPI indirect mode using STM32G474 and STM32H753.However, I found a weird operation of QUADSPI_BK1_IO3 pin.Other pins are OK, but QUADSPI_BK1_IO3 is high states as in the redboxes.It should be low states (0).I have tested in STM32G...
