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...
Posted on January 16, 2018 at 21:37I am new to CubeMX. How do I configure a pin as and interrupt? Also how do I setup Low Power sleep mode to wake up with WFI using CubeMX?
Posted on January 17, 2018 at 14:44I have a problem with a project based on an STM32L051. I want to use the stop mode and wake up on an external (GPIO based) IRQ. This all works great but after the MCU woke up, no other IRQs seem to work. I have a v...
Posted on January 08, 2018 at 14:32Hello,in your first project we use a STM32F415ZGT without any problems. Then we switch to the smaller version STM32F415RGT in a new design. With the same source code we got some times a hard fault when die MCU is b...
Posted on January 15, 2018 at 17:31Hi, I am in the process and nearly completely writing a bootloader. The bootloader will load small sized programs, however if I load a large file then it goes wrong. I ave tracked this does to the writing by readin...
