The STM32 family has fantastic interrupt service, they stack a whole slew of extra registers for you, and load the LR with an artificial return to properly unstack while looking for opportunities for tail chaining, aborted entry, etc etc. HOWEVER.......
Hello community, I'm new to ST-MCUs, so maybe this question is very basic. I'm developing an application for a customer board with a STM32L051R6TX.For Communication we use USART1 und USART2, for logging I activated LPUART1.On USART1 und USART2 I get ...
Hi, with my team we are currently investigating the low power features of the STM32L4R9 MCU on a DISCOVERY board. We are measuring the current consumption on JP1, plugging an external amperemeter between pins 3 and 2.We would like to check the datash...
Hi everyone,I am trying to implement SRAM Parity bit check in my application. But when I am enabling it from option byte. and then it is going into Hardfault whenever I am going into debug mode before running application even it is going into .Hardfa...
I'm using the STM32L496 and attempting to get the CAN communication working with the embedded bootloader. I can put the device into boot mode, but as soon as I send a CAN frame (0x79 Identifier, or any frame for that matter) the device seems to jump ...
Currently any one of the CAN channel is Working at a time.Out customer requirement is, they need both CAN channel's need to work at the same time.Please can you explain me and If you have sample code, please attach here.
Hi, I ordered some STM32U585CIT6 for private use at a distibutor 4 month ago and I'm still waiting. Reason: "Problems in production".So far I know, SOP for the Stm32U5 familiy was announced for Q3/2021.That means, that you have unsolved problems in p...
Hi, I use STM32H7A3LIH6Q in my project. Now we have two prototypes and I could program and run them at the beginning, LED is on or blinking. Later when I started to test the DC/DC converter, both boards had LED (driven by MCU) off, and can not be pr...
Hello,I am using freeRTOS on dual-core of STM32H745I disco dev-kit.Where I am able to print debug messages using "printf" function in core M7 using UART3 but not able to print messages using "printf" function.I have followed the https://community.st....
