My hardware design doesn't connect the BOOT0-Pin to a specific voltage level. That's why I need to write to the OPTR Register so that the BOOT0-Pin is not read at the boot sequence.I check the OPTR Register:FLASH->OPTR = ffeff8aa RDP = aa ...
Hello Comunity,I am trying to receive data with stm32h745 from stm32f407. In polling mode and IT mode no issue of getting multiple bytes of data. But with the DMA I can only receive and transmit one byte of data and nothing more. DMA is configured in...
I use STM32H747 eval board to try to develop my application.In the standard example the two MCU (m4 and m7) boot togethere and then M4 goes to STOP mode until M7 Release HSEM.I want to to the same thing but i need to M7 goes to STOP mode and M4 resta...
Is the I2C configuration tool STSW-STM32126 applicable to STM32H7?Or, is there a version for H7?
we are looking for this very long time for our end customer Edwards life sciences project
My STM Nucleo G031K6 board has a very simple app running on it.It simply outputs a PWM signal from 0 to 100% duty cycle and then resets and starts over.It runs this into a TIP102s Base with 1K Ohm resistance between them.However even at 100% Duty Cy...
Hi,I have another round of corrections for the DS13560 and RM0444 documents, i.e. the STM32G0B1RE datasheet and the STM32G0x1 reference manual.On the datasheet page 35, chapter 3.26, the RAM reserved for the FDCAN module is specified as 1-Kbyte where...
Hello,I want to use a STM32F7 to retrieve ADC measurements from an external ADC over SPI (16-bit read operation to retrieve the measurement). In theory, it should be possible.My question is: how can I retrieve the measurements minimizing the host pro...
Currently have the code working on most laptops and tablets I have tested to provide power along with display. However currently testing on a windows surface tablet and its doing strange things please attached cfg fie. Any ideas or help would be very...
I use nucleo-g071rb board. I want to read Infrared datas via IR Led and send it to another IR receivers with different IR Led. For purpose I used timer2's channel 1 with input capture direct mode. I used dma here to see datas. I have a problem with d...
