I have a STM32H7 and I use USB MSC. I do not use an RTOS.If I plug in my USB thumb drive I append a counter to a file and close it.This works.If I remove the thumb drive very quickly at precisely the wrong moment I get a hardfault.if Appli_state == A...
Hi everyone,So, I have FDCAN working in internal and external loop back but when I connect it to an external CAN bus and switch it to standard operation I get nothing. I know there are messages on the CAN bus because I have a CAN scanner on the bus t...
Hello, Right now I am working on a Riverdi display, actually the RVT101HVSNWC00-B.I was able to connect with their external loader and to save the firmware in Bin and Hex formats. I wanted to review the firmware, as loaded, in CubeIDE. How would I do...
I've tried so much stuff from official examples, unofficial examples, AI, debugging, forum posts, etc., that at this point I think it might be best to describe my understanding of what should be necessary to access the onboard microphone, and hope th...
Hi, I'm using STM32H745-Disco kit. facing some issues while testing, Initially able to configure in STM32Cube IDE software, STm32Cube programmer and STM32CubeMX software's tool without any issues. Now working on testing an hall effect s...
Guys, it was really hard giving birth to this proof of concept: - Every 100ms the timer hits the ceiling , lessons leaned : trigger event selection setting is irrelevant, it'll work- in the TIM2 ISR (more precisely : the user callback TIM2's ISR is c...
I use a STM32H750 chip and I would like to use the emdedded bootloader with the FDCAN1 interface. AN2606 specifies pins PH13 and PH14 for this version. However, the package I use (STM32H750VBT6 LQFP100) doesn't have these pins exported. Does it mean ...
Hi,We are trying to interface ST33KTPM2I3WBZA9 with STM32H735IGT3 using I2C communication.We have used following commands and logic for communication. #define TPM_I2C_ADDRESS 0x2e << 1 #define TPM_REG_ADDR_COMMAND 0x00 uint8_t command_data = 0x...
I need to compress voice in STM32L4. Here are my requirements:* STM32L4 run at maximum 80 MHz* Voice to be sampled by ADC/DMA* Flash usage for voice compression < 50 kBytes* RAM usage for voice compression < 64 kBytes* Compressed data < 10% of origna...
This behavior seems like a bug.I’m using USBX CDC ACM on a H723 nucleo board. I’m trying to work with the blocking nature of the ux_device_class_cdc_acm_read. For my application, I would like to get data as soon as up to 256 characters are received b...
