Hello, My STM32F7 crash after Reinit the UART : - I have an UART for my RS232, and I can communicate to 2 devices by this RS232. So the customers choose on which device he want to send data, then I configure internals variables and the UART baudrate ...
Hi community,I have a problem where Ethernet does not work when VOS is set from scale3 to scale2 or scale1 on a customer board.Please help us solve the problem. Clock and peripheral settings use code generated with CubeMX v6.9.1. The CPU is STM32H745...
All:We have a custom board with STM32H723 where VREF+ is set to 3 volts.When I feed ADC3 input 2 with a value of 0 volts, I get 118 counts on the 12-bit ADC, 1.48 volts gives 1385 counts, and 2.95 volts gives 2600 counts.Earlier work with Nucleo boa...
Hello,We are using the STM32C0 in a low-power application. We initially selected the part with 12K SRAM in case we needed to use more than 6K, but after development have found that we can make do with 6K. I am curious if there is any power savings ...
Heyho,I just made an interesting observation on the STM32H735 Discovery concerning the internal core power supply.I'm working on an ethernet bootloader for my custom board using an STM32H733, which has no internal SMPS, only the LDO.As I do not yet h...
Hi folks,I use MX to generate a code for STM32L4. I noticed, when I configure timer in one pulse mode, I cannot set OC CH1 in PWM mode with CubeMX. I could set it manually after code was generated, but it would be overwritten if I run MX one more tim...
Hello everyone!I'm trying to communicate with a slave device (ICM-42688-P: https://invensense.tdk.com/wp-content/uploads/2020/04/ds-000347_icm-42688-p-datasheet.pdf), but I don't recieve anything on the MISO line. I'm using the nucleo-wb55rg for the ...
In my device based on STM32U535, I use the internal RTC with LSE with external 32.768KHz crystal as the clock source. The VBat pin is powered with an external rechargeable battery. The charging is done externally, and the internal VBat charger is not...
Hello, I am trying to use the STMicroelectronics classic USB device middleware to implement a CDC class in the STM32U575 microcontroller. I am currently working on NUCLEO-u575ZI-Q. At first, I followed the tutorial on "How to use STMicroelectronics c...
Hello everyone,as I am developing keyboard with extra keys adding to the existing key board. I am adding extra modifier keys to the key board to perform the task. kindly let me know will it work and give suggestion inputs. my customized keyboard cons...
