Hi All, I've created a PCB (same happens on the Open107V dev board) and I'm finding that the I2C comms is failing unless I have an external capacitor of 22pf connected from the SDA line to ground. I know the aim is to keep the capacitance as low as ...
Hey guys and gals! I am facing a persistent problems when configuring system clock on the STM32L152 to 32MHz using SPL. It smoothly runs at 24MHz but always freezes when making it to run at its maximum freq.The MCU's max clock frequnecy is 32MHz and ...
Hi,I am trying to post an issue and getting "Looks like you don’t have access to create a case. Ask your community manager for access"Can you please give me access.ThanksSharon
Hello I am working with the STM32f4 development board. I'll make one LIN(Local Interconnet Network) master and one LIN Slave instance but I don't have any example. Has anyone created a sample code? or ST?
Hi AllAs to GPIO EXTI interrupts:Does the stm32h7 supports level interrupts?or just edge triggered interrupts?According to arm cortex m7 specification it should, I don’t see it on the ST documentation.What happens if I use a level triggered IO which ...
HiI'm about to be using the STM32H743 to a project, were is should communicate to an 8 bus parallel ADC. Is there maybe someone who can guide on how this can be done, maybe there is an example, tutorial or other documentation of how this can be done ...
Hello,what is the value of USART->DR (RDR) is read twice after receiving a byte? E.g.Byte 0xFF received, RXNE flag set.DR is read into variable, RXNE is cleared, the variable contains 0xFFDR is read into variable, the variable contains ?Does the DR h...
The CAN bus transmit some raw data at 500Kbits/sec and is transferred via transciever to pins PB8(Rx) and PB9(Tx).I tried to configure the followed values from the cubeMx platform (since my CLK on APB1 is 42MHz): prescalar=6, TimeSeg1 = CAN_BS1_11TQ,...
