Posted on January 16, 2018 at 19:36This text suggests that there's a need to use PLLSAI only if PLLI2S is programmed to these two particular frequencies. This is confusing.While there are two disjunct groups of popular audio frequencies indeed, and ...
Posted on January 16, 2018 at 01:33Hello,I've got a simple control loop and I need to track the elapsed time of each loop. Duration will be anything from 2u-sec to 500 u-sec. I'm wondering if there's a system clock tic register or countdown timer ...
Posted on January 17, 2018 at 15:57This isn't a question, but a suggestion. I've always had trouble running AC6 Eclipse 'Updates', I'd usually get a 'Connection Reset' error, over and over, until one day it would work. Previously, I'd assumed the ho...
Posted on January 17, 2018 at 21:51When I initialize UART4 registers in STM32 micro-controller, I get this error, *** error 65: access violation at 0x40004C0C : no 'read' permission*** error 65: access violation at 0x40004C0C : no 'write' permission...
Posted on January 17, 2018 at 21:33Hello,I've have the I2C example code I2C_TwoBoards_ComIT working between an F722 board and a F303 board. That example passes a fixed size character buffer between the two boards fine. As I start to modify the cod...
Posted on January 17, 2018 at 16:07Where can I find the alternate function mapping for GPIO pins? Normally these can be found in User Manual for a given card, but I can't find it for the NUCLEO-F303RE.
Posted on January 16, 2018 at 12:09Hi,I would like to know how to use the USART2 on my board (integrating the STM32L052k8 mcu) to communicate in SPI with an external slave.Is it possible? How can I do it? Is there an example or a snippet which I can...
Posted on January 15, 2018 at 21:51I am trying to get the SDRAM working in the STM32H743 Eval board. If you select the Eval board in the Cube, it sets up the pins for you, but does not fill in the memory settings. I have made my best attempt to do t...
Posted on January 13, 2018 at 21:45Is there a way to determine the line of code or PC address that caused a call to the HAL_WWDG_EarlyWakeupCallback?Perhaps print the previous stack entry address?Thanks!X
Posted on January 17, 2018 at 14:42Hi,this might be a stupid question because datasheet says there is no ADC in pin PA9 on a STM32F407VGT, so what i am probably asking is if there is any way of working around this / finding a hack?Background is tha...
