Moved from the MPUs forum - H7 is an MCU, not MPU
I am a complete beginner with STM32, and I'm currently working on a project where I need to transmit a simple 16-bit ADC value to USB using my STM32H753VIT6. I'm trying to figure out things myself, but I seem to have encountered an issue and could really use some guidance.
Here’s the situation:
- When I started the project, all the basic peripherals were running at a 64 MHz clock speed.
- To improve performance, I increased the clock speed to 480 MHz for the peripherals that can handle that.
- I then adjusted the ADC clock to 100 MHz, and everything seemed to work fine (the IDE supported it without showing any errors).
- However, I then changed all clocks to 120 MHz, the ADC clock to 64 MHz, and kept the USB_OTG at 48 MHz (I never changed this one).
- After flashing the STM32 with these settings, the device is no longer responding and I cannot reprogram it.
I’m completely new to this, so I’m not sure where I went wrong. Could this be a clock configuration issue? Is there a way to recover the device and reprogram it?
Sorry if I did something foolish, but I’d really appreciate any help or suggestions on how to proceed!
Thanks!
