There are several good options for implementing an MCU bootloader from an embedded Linux host. Unfortunately, I have hardware that is already in production and therefore I am not able to implement any of the industry standard and simple ICP (In-Circu...
Hi Community,I recently started working on OpenBootloader on a NUCLEO-G491RE and was trying to understand its operation. As an initial step to understanding the protocol and operation used a terminal and sent commands manually those can be found in t...
I am trying to set-up the demo-kit for Acoustic Echo Cancelling and I am a bit confused about steps 1 and 2 of Getting started with the STM32Cube function pack for acoustic echo cancellation - User manual in part 2.3.1.On my boards bridges that shoul...
HiWe are using the DISCO-L072CZ-LRWAN1.USART-5 uses pin PB3 for Tx, is this pin not available on the LoRa development kit ?Is there a way to re-route the USART-5 Tx pin or access it ?thanks
I'm trying to get the ethernet working on the nucleo-F746ZG eval board.I've found the LwIP_HTTP_Server_Netconn_RTOS example which works great(first time EVER for me, that code on embedded device actually worked without spending several days to fix th...
UM2411:Caution: The I/Os of the STM32 microcontroller are +3V3 compatible instead of 5 V for ARDUINO ®Uno V3This mean can not conect to Stm32h747-Disco with pines for uart to arduino directly o no ? If hay problem with this how to send data o solve t...
Hello, I have the STM32G474 Discovery Kit and am just attempting to get a blinky LED program to work on it for right now. In the STM32CubeIDE, I imported an example, was able to get it to build correctly (after changing references from caddr_t to voi...
If I register a callback function for GPIO EXTI and I have EXTI on multiple ports for the same pin (e.g. PA0 and PB0) how does the callback distinguish between the ports when the event triggers?
Hello I have set the timer7 for 1 minute interrupt. It is working at every minute as expected. But the interrupt is also triggered as MCU is reset. I have set global counter for increment in timer7 callback. As soon MCU is reset , Timer7 callback is ...
Hi,a footnote(4) in STM32H7 reference manual RM0468 Table 56 regarding the maximum allowed frequency for ADC says"With a duty cycle close to 50%, meaning that DIV[P/Q/R]x values shall be even".Does this recommendation apply to the actual DIVXx regist...
