FX_IO_ERROR - LX_SYSTEM_INVALID_BLOCK
Hello, I am trying to install FileX + LevelX in an stm32h7 microcontroller using a nor custom driver. I do have in my hardware an AT45DB641 NOR memory. I am working it as an stand alone and also with fault tolerant enable. My flash chip does have 40...
USB-C Power Delivery Sniffer with Nucleo-L152RE
Hello, Is there an option to use with Nucleo-L152RE as Power Delivery CC line sniffer and decoder?As far as I know to allow to sniffer cc line protocol it should have the ability to use Manchester decoder.Thanks,
Resolved! DMA RX complete interrupt sometimes not called in STM32L4
Hi everyone, I've done these steps before on STM32F0, STM32F1 and STM32F4 microcontrollers to detect when a circular DMA buffer for UART "wraps" (The counter finishes with the array and starts from the beginning again) with complete successActivated ...
Resolved! Timer update generation delay
Hello,I am verifying timer functionality on an STM32F303K8 Nucleo development board. After generating an update event, the counter register does not update immediately - in downcounting mode, it takes several nops for the counter to read the same as ...
Regarding the issue with the input data rate of DFSDM？
If DFSDM uses internal parallel data input, such as direct write to input register or DMA writing, what is the maximum frequency of input data in this application?
How to dynamically reassign the pin?
Originally, I configured PB6 to work with OneWire using DMA! However, after some time, I need to use the same pin for operating an LED!Below are the steps to reset the pin settings to default.1. Stopping all processes associated with using DMA on pin...
HAL_GPIO_ReadPin is always returning High. Why is it not working?
Posted on November 21, 2014 at 19:59 I'm having problems reading the state of a GPIO pin. If I use the HAL function to read the pin, it always returns that the pin is high. But if I read it manually, then it works properly and co...
Differences between Revisions of STM32F205
Hello,There are 8 revisions of the STM32F205: 'Y', 'X', '1', 'V', '2', '3', '4' and '5'.The silicon errata shows the status of support for all revisions, with no mention of individual revisions.Does this mean that all revisions are the same?Is it cor...
Resolved! Flash erase blocking GPIO updates
I am testing doing flash erase while running code from internal SRAM on a STM32F072B Discovery Board. Having initializing everything with code running in flash, I call a function where itself and all its dependencies exist in RAM. I've verified this ...
