Hi everyone. I am driving a Neopixel LED with a PWM signal in DMA mode using a timer. Even though all variables are the same, my code works with timer 3, but the same code doesn't work with timer 2 with the same timer configuration. Why could this ...
Split from this thread.Hi there, switching to USART3 didn't work. I still don't see any messages in the serial console. the second time I try to connect to the serial console gives this error.
Hi, we are developing a device which outputs display port over type-c and needs to sink power. Similar to Laptops when connected to hubs. The required power is less than 60W. Im looking a for a suitable USB-PD implementation for this purpose. Can thi...
Hi all,After reading through both the HAL, low-layer and USB Device library code flow several times I am still confused about a peculiar point.When I ask STM32CubeIDE to generate a Custom HID base implementation, I get a "usbd_conf.c" file that has a...
I'm using a B-U585I-IOT02A board and the IOT_HTTP_WebServer example code. My read is the PSRAM is 8M on that board, but I can only access 16K (to 0x2803ffff) and then ???? is not IDE memory display or a trap in the code. Is this a CPU configuration ...
Currently, on the STM32G474, I am able to perform on-the-fly flash operations and interrupt vector relocation using BF_MODE and VTOR. However, I have encountered an issue: when a function is placed in RAM using the ramfunc attribute or located in CCM...
IssueHigher ambient temperatures cause communication malfunctions with XSPI memories.DetailsOur design is heavily adopted from STM32H7S78-DK which also has the same issue described below.The application uses memory-mapped mode for both Flash and RAM ...
Hi All!I try to use 2 pieces of IS66WVO32M8 PSRAM with multiplexed OSPI ( only the NSS pins not shared ) with STM32F585 in memory mapped mode.Previously, I used 2 pieces of APMemory's APS12808L in memory mapped mode without any issues.I reconfigured ...
hi ；During the operation of STM32H723VGT6, the constant input bus error and hardware error interrupt occurred, and the clock is 280M. The PWR_REGULATOR_VOLTAGE_SCALE1 is unstable. The clock configuration __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_...
Hi Im Lalin, Im using STM32L433RC-P MCU for learning.Im facing the issue in reading the data from ADC.Im not getting any error too.Below are the source code attached.Kindly help me to find the solution for this.Note that im using uart.c for debugging...
