Resolved! how to store signed hexadecimal data from a sensor and identify if the hex is negative or positive?
I have a sensor that can communicate via UART, I send a command and the sensor answers me with a hexadecimal frame.I can have distance, angle, velocity values. I know how to store the frame in a buffer but I don't know how to store it in hexa to kee...
How to find where RXNEIE is reset to 0
Hello,I'm debuging some legacy code for an STM32L476RG MCU. USART2 is enabled, and used as an UART, with DMA for TX, and one interrupt per received character. I'm using STM32CubeIDE 1.8.0.Each time a character is received, the HAL_UART_RxCpltCallback...
wake up logic on stm32l4
I want to wake up from standby for each transition on a wkup pin. For example, on waking, read the wakup pin and set/reset the bit in pwr_cr4. (pin high -> bit high, pin low -> bit low). Is there a race condition ? The reference manual is vague on...
I2C Master Sequential function
Dear,I currently use a STM32G070 with external touch sensor component usuing I2C interface.This component aloow me to communicate with it only during a ready window and this window is automatically closed after a delay without communication or a I2C ...
Resolved! STM32U5 documentation error in HSI -> TIM5 interconnect section
In section 16.3.7 of STM32U5 RM0456 Rev 2, the following text appears in the bullet that notes MSIK, HSI and LSI are linked to TIM2/TIM3/TIM4/TIM5:"External clock mode1: Table 446: Interconnect to the tim_ti1 input multiplexer for TIM5, tim_ti1_in1 (...
Can sdio f_mount affect UART port?
Hi!I have a problem with the simultaneous use of an SD card (with SDIO) and the uart port with GSM module connected. The SD card works flawlessly all the time. Communication with the GSM module is very unstable when I use the SD card - using the f_mo...

STM32G031xx: Mistake/Bug in device specific header file???
Hiso I am trying to get the UART2 on my STM32G031K8Tx up and running. RefManual shows in Chapter 5.4.21 a CCIPR register (Peripherals independent clock configuration register), where bits 2-3 relate to the USART2.When looking at the device specific h...
