STM32H745 UID_BASE how to accessible from M4.
I'm working on H745 dualcore MCU and I'm trying to get STM32 UID from M4 core accessing to addres 0x1FF1E800UL. Reading datasheet I can't find explanation why that address range is not accessible.
Upgrading CubeIDE1.9 to 1.12
I created many projects using CubeIDE1.9. I now installed CubeIDE1.12 and need to open my projects in the new version. I copied my old projects to a new workspace I created and then tried to import/open projects using CubeIDE1.12 but got a generic...
STM32F446RE phase-shift modulation for DAB converter which needs 8 pulses, which are in complementary pairs.
I am new to STM32 and I am trying to figure out how to implement my PSM control. I need 8 pulses which are in complementary pairs. I need to use TIM1 for the 2 pairs and TIM8 for the other 2 which are advanced timers. I want phase shift between the f...
how to connect more than 2 chips over I2C ?
I have custom board with 4 chips, communicating over I2C. The problem is that I cannot have 4 chips talking to each other.I can only communicate between 2 chips. As soon as I enable I2C on third chips the communication stops. One is setup as master t...
I2C SLAVE perform Long clock stretching but 2 units MASTER and SLAVE are configured with the same Frequency
Hi,i am using 2 units of STM32h743II MCU and I am trying to transfer I2C transactions from master to slave based on I2C_TwoBoards_ComPolling examples.data is received correctly each time but about my i2c slave unit perform Long clock stretching 1 out...
ADC enable after calibration process in STM32G070
I read the example code of ll adc single conversion in stm32cube g0 package, and I have a doubt in a particular section of code: /* Run ADC self calibration */ LL_ADC_StartCalibration(ADC1); /* Poll for ADC effectively calibrated */ ...
26 ADC inputs
Which nucleo board should I use for 26 ADC inputs?Or should I use a multiplexer? Can I get fast signal processing with a multiplexer?Thanks
How to Fix X-NEUCLEO LPM01A
I'm monitoring power using an X-NEUCLEO LPM01A and an STM32F767Zi target board. When I use them in standalone mode and connect to a desktop computer, the X-NEUCLEO LPM01A stops working. Can someone tell me how I can repair this?
Do I need ST-LINK/V2-ISOL for STEVAL-ETH001V1?
I bought the STEVAL-ETH001V1 and it is without the firmware loaded.I was previously working with the P-NUCLEO-IHM03 and the B-G431G-ESC1 so I don't have any programmer for the MCU.I think I have to buy the ST-LINK/V2-ISOL but I'm not sureBest regard
