Hi, We are using a STM32H745 in our project. Over the past few days, I've been wasting a lot of time figuring out why RTC has a major error ... it always runs slower than it should. To be sure we tried to used the crystal and the capacities present i...
Hi, If you set a timer in Output Compare in Mode "Toggle" and assing a Chanel to a pin of your uC you can make it toggle when CCRx == CNT. That works just fine, as expected. My question is: when you configure the Mode of that Channel to “Active on Ma...
Hi everyone, I try to understand more deeply the the whole clocks issue and how each frequency affects the running time. My board is STM32F429, and the clock configuration set by default (maximum values). This is the best configuration for fast runni...
In RM0008 cha 27.3.4 talks of " Fractional baud rate generation" and goes at length with examples of those fractional number. If the "fractional" stuff is broken down to integers, it boils down that simply baud = f(clk) / BRR.Or, as libopencm3 write...
I am looking 100pin STM32H750 but nobody has them in stock. Digikey, Mouser, Distrelec, TME all zero. Is there something newer or what is the problem.
Hello everyone, I'm new on STM32.My Board is blocked in this state (see on the photo) : 2 led at red state continuously.And when I try to load program in the board, this type of erros occured : Error launching GDB server.Thanks for your Help !
I am not able to transmit my data while giving query for rs485. so as a result no receiving data too. I have selected baud rate 9600 in both energymeter and my uart also. I have selected USART1 , PA9 tx, PA10 rx and GPIO PD11, Module used is Max485 ...
Hi Is there a test procedure you guys follow when you BringUp MCU with new a PCB board?Beside testing interfaces like UART, I2C, Ethernet, Etc.. how do you test the internal MCU Configuration: registers configuration Clocks and PrescalersAXI BusCPU C...
In my project I have to share some info among the two cores in the STM32H755 controller but I'm not able to find some simple example about the use of IPCC. Yes, there are presentations etc, but STM32Cube_FW_H7_V1.8.0 repository doesn't provide one.
Hello,I am trying to set up a FDCAN communication between two STM32G431KBT6.The Tx part seems to work perfectly but I have a problem at the level of the reception.General informations: I use CAN-FD as a standard CAN 2.0B (Extended Id) at a baud rate ...
