Problem with CLASSB STL_ClockStartUpTest
Hi,In the snippet below, comment says select PLL as system clock but in code it is configured as HSE clock which one shall be considered? /* Select PLL as system clock source and configure the HCLK, PCLK1 and PCLK2 clocks dividers */ RCC_ClkIni...
Resolved! Is it possible to just replace a STM32F072xB with a STM32L452xx with the same pinouts ?
For the package LQFP48 the pinout is the same. Also Pin names are the same. So is it possible ?
AI relocatable run-time API lets the MCU HardFault.
Hi,I'm testing running a relocatable binary model.But when I use ai_rel_network_run(), I get into HardFault.The detailed error information is as follows, with my current test code attached.Hope that someone can help to resolve this issue!Thanks. /* U...
Resolved! STM32H735 UART2 HAL_UART_Receive_IT and HAL_UART_Receive puts a first byte in the buffer that is not there.
I am a bit frustrated with the USART2, which is connected to the UART9 TX9-RX2 and TX2-RX9. So with sending from TX9 to RX2 everything is fine but the other way around there is a first byte = 254d inside the receive buffer. huart2 and huart9 are init...
What might be a root, if my internal reading value of ADC from "VREFINT_DATA" is fluctuating?
Hello together,im using in my project the µC "STM32F302C8T6-LQFP48 pinout" on a self designed PCB with another HW-components and a part of this project is to measure ADC values, which I do over DMA. Generally, it is working, (when I supply only the P...
Resolved! Sector erase OSPI on STM32L4P5G Discovery Board timeout
Hi everybody, I'm trying to delete a single sector of my STM32L4P5G Discovery Board MX25UM51245G OctoSPI Flash memory but I always end up in a timeout. Reading memory by function BSP_OSPI_NOR_Read() is working as expected. I'm using the bord support ...
Resolved! STM32 U575 LSE Clock doesn't start.
LSE clock is set in the Cube and initialisedAfter intitialisation the following registers are not set correctly and the LSE clock isn't calledRCC->BDCR->LSEDRIVE not set to hight event though macro calledRCC->BDCR->LSCOSEL set to LSIRCC->BDCR->LSCOEN...
stm32 uart interrupt stops working after ~1 hour
I am using an STM32L073 chip. I have 2 UARTs but only the huart1's receive is using interrupts. I start the Rx interrupt at start-up and then the interrupts are being set at the end of the interrupt function. (see code below)My issue is that after ab...
