Using Nucleo H743ZI2semihosting with printf and CLI using sprintf I am unable to get the runtime library set to Reduced C to work using float/doubles. Standard C works with floats as expected. The initial stack size was 0x400, I have tried up to 0x16...
I'm programming a firmware with USB CDC support on an STM32F405. I noticed that when I connect the board to my system without working firmware running, all USB devices start glitching out. Every second, the mouse cursor stops moving for a moment. Thi...
Hi,Looking for ANY references to or better yet, a coded example of how to set up an STM32L processor with FreeRTOS and wake up from STOP0 mode on an RTC calendar event.FreeRTOS and sleep mode isn't an issue, that works fine. However anything more tha...
I use STM32F207VGT6 with noRTOS. And also I use fatfs uSD and USB drive same time.I have problem with f_open.Firstly I define filename arrays on the top of the file as the following order:When start of the program I controlled if uSDcard is mounted o...
Hi,I'm currently developing a board where I use STM32L433RC as my main unitof processment. This board will have an SD Card to store some data and later ontransfer it via UART. To achieve this, I must use an UART to Serial Portconverter.After some res...
Hi,Iam trying to write some data (i.e. 8 bytes) via the WriteMemory command of STM32L45xxx bootloader to the STM32's SRAM area (in particular to address 0x20000000). However when I connect to the device and look into the memory the data is not take...
I am trying to implement hid otg with stm32f105But you can use micro 5pin as otg usb connectorUSB communication does not work with the normal connector as shown in the picture below.I wonder why it doesn't work depending on the usb connectorAnd is th...
Which Software you are using to monitor the Receive and transmit data from USB. Do you have any suggestions for the USB data Loggers ?
So this might be a easily answered question, and I think I know the answer, but I just want to confirm for safety:If a bootloader program for an stm32l4 (or any family of chip) is set up to run at a different clock frequency than a firmware package o...
Hi have the use a USB aplication with STM32L151CBT6ATR, but this uC have not a dedicated pin for VBUS sensing, how is the way to resolve that situation ?I readed AN4879 and usb_20.pdf specification and not are cleare for me.Much apreciate any solutio...
