tying to find what frequency the hsi is at startup and normally i search the datasheet for clocks and startup but this returns nothing in the datasheet for the stm32h753bi mcu only thing i see is that it has 4 clocks and it says the hsi is 64mhz is ...
Hi All,I have interfaced Winbond W25Q128 external flash and IS42S32400F-7TL external RAM to STM32H750IBK micro on my custom board. I have found an external loader file (stldr) for my pin configuration from a community member.I can program, read and ...
For my project, I need to use a parallel RGB interface (8 bits) to control a display using Nucleo-F411RE. The PCLK for the RGB interface is required to be a minimum of 1MHz.However, the STM32-F411RE does not have any LTDC peripherals. So I implemente...
Hi, I'm new to embedded (as in one week old) and am trying to build a small system to do a few things for an optical product we're building: mainly temp measurement (Omega SA1-RTD with MAX31865) and LED management for optical lasers. Currently I have...
Hi,I am using stm32l412 controller with an external flash w25q128 in quadspi mode. I am able to read and write on to the flash memory. but I am unable to use it as an external loader. I referred many tutorials, I edited the linker script to add a sec...
Hi all,Can anyone confirm if these two type of STM32 MCU, STM32H753BIT6 and STM32H753VIH6 use the same die although they have different packages? Best fourhes
STM32L072 has USB as Additional Functions instead of an Alternative FunctionThough in one of my Earlier Post It was briefly explained, It felt to have a Dedicated Post in General Thereby this Post to Better Understand the Difference and Way of Workin...
PLEASE IGNORE THIS POST AS I SOLVED IT I TRIED TO DELETE THIS POST BUT THERE DOES NOT SEEM TO BE A DELETE OPTION? Hi,trying to read the temperature of one of the simplest I2C temperature sensor ever... the TMP1075 (datasheet attached).The bizarre th...
I am having trouble configure the USB-C port for serial output. The board I got is a "BlackPill" and I have went to try some example code for USART2 and USART6, however, upon a reset, I still do not have a COM port appear. Any advice?
Hi all, I have a problem with a new version of an existing PCB using the STM32F334C8T6 microcontroller.Known working code is loaded onto the new PCB, power is applied and the MCU starts up the clock and then seems to sit idle. If the NRST pin is then...
