How to integrate the M24512 EEPROM in stm32f303?

STM32F302R8 - Not giving DAC output.

I am using the STM32F302R8 for motor control application. Need to do pulse-by-pulse current limiting.I have a BLDC drive board that has a comparator that can be used to give shutdown signal to the PWM. For this purpose, I need to give the comparator ...

Can I use Python to program STM32?

I purchased a controller board from HiWonder, who use your STM32 MCU. I asked them if I can use python to program the STM32 but they do not know. Can I use python to program your microcontroller? Do I need to download specific software?

How do I receive an arbitrary number of bytes over a slave SPI peripheral using DMA?

If I want to receive a known number of bytes I can use the library function: HAL_SPI_Receive_DMA()But I would prefer it if when nSS falls to check how many bytes have been transferred and interrogate the DMA buffer.An alternative is to poll, using F...

Resolved! On my STM32L476RG, my LPTimer does not work when in STOP1 mode.

At startup I do initializations, then go to STOP1 mode. Initializations include setting a wakeup in the RTC and setting the wakeup clock to the MSI clock. The RTC successfully wakes the MCU. In the wakeup callback, I do some things then start a LPTIM...

Resolved! Is there any app, similar to "st-link utility" that i could use with a android tablet?

Hi,i develop 100% of my code in my workshop or office, but sometimes i wish i could do some very light modification to a parameter or baud or something in the field and i dont really fancy carrying my expensive workstation laptop around. So i wonder ...

STM32H753XI Evaluation board - HAL_SPI_Receive() function return HAL_ERROR due to timeout for receiving data on SPI. What could be the problem?

Hi,I'm having a problem with SPI interface. I am using STM32H753XI Evaluation board. When I issue HAL_SPI_Receive function I get HAL_ERROR due to timeout for receiving data on SPI. What could be the problem?I attached my core dir.Thanks in advance.

Resolved! MDMA transfer not working STM32H7xx

Hello,I've been trying to transfer some data from AXI-SRAM to DTCM via MDMA but it seems not functional.The transfer occurs the flag of end of transfer is set yet the data that I have in my DTCM isn't the orignal one contained in the AXI-SRAM.Also im...

Resolved! HardFaults at random places in code on an STM32F722

Hello,I am facing random HardFaults on a STM32F722. They happen at various places in code, sometimes even during stack's initialization.Stack's analysis do not show any risk of overflow : most of the time, the problem happens while executing main() l...
