I am using an STM32f746zg and this is what I have been trying:HAL_FLASH_Unlock();CLEAR_BIT(FLASH->OPTCR, FLASH_OPTCR_IWDG_STDBY);HAL_FLASH_Lock();But it doesn't seem to actually modify the bit. What is the proper procedure to clear this bit in flash?...

Hey guys,As I said in the title, I am using SPI6 on my nucleo-f746zg board as a slave. I have it set up to interrupt when a GPIO is low and then it it tries to receive/transmit using the HAL_SPI_TransmitReceive_IT function, but it seems to always int...

Hey guys,I am working on communicating to an ISM330DLC sensor using I2C and a TI processor as the master. We only have the accelerometer enabled (no gyro) and are using the FIFO to read the data. When the FIFO gets four pieces of data (2 x, 2 y, and ...

I am using an ISM330DLCTR IMU currently and have a FIFO running in continuous mode with an ODR of 6.66kHz. I was trying to get the accelerometer and gyroscope to both run at ODRs of 6.66kHz, but when I try this, most of the data is garbage. It seems ...

Ah, I was calling that after I locked, so it wasn't working. Looks good now, thanks for the help!!Thanks,Charles

On startup I am trying to check if those bits are cleared, if they aren't I clear them and then force a watchdog reset. Here is my code:// Check if the watchdog pause on sleep bits are set. If they aren't, set them and reset. HAL_FLASH_OB_Unlock()...

So I've gotten it to clear the bits properly, but they don't seem to persist on reset. I've been resetting by just allowing the watchdog timer to runout, is there a better way to reset?Thanks again!!Charles

I've resolved the issue, it ended up that I needed a pull-down on the SPI clock to keep it low at startup.Thanks!!Charles

I tried adding a delay in the interrupt handler, and it still doesn't seem to work. I've attached an image of what I'm seeing, it seems like no matter how large the delay is, that is what my output always looks like. The data the SPI is reading in is...

I am trying to clear the IWDG_STDBY bit set in flash so I can enter standby mode without the watchdog timer waking up the MCU.

I am trying to use a nucleo-f746zg as a slave using SPI6, but it seems to be dropping the first bit.

When reading from the ISM330DLC using I2C, the sensor sometimes stops responding.

Are there ODR limitations for the ISM330DLCTR accelerometer and gyroscope when using the FIFO in continuous mode?
