Hi, I use STM32H7A3LIH6Q in my project. Now we have two prototypes and I could program and run them at the beginning, LED is on or blinking. Later when I started to test the DC/DC converter, both boards had LED (driven by MCU) off, and can not be pr...
Hello,I am using freeRTOS on dual-core of STM32H745I disco dev-kit.Where I am able to print debug messages using "printf" function in core M7 using UART3 but not able to print messages using "printf" function.I have followed the https://community.st....
I am Sudhakar from Rennova solutions Hosur. We have a plan to design 1kW CC-CV OFF BOARD CHARGER for TWO-WHEELER. I found an application note AN4856 using MCU STM32F334C8. If ST have any design tool/worksheet for 1kw. Can you suggest a suitable MCU ...
I'm using ADC1 of STM32L452CC. Multi ADCs are connected to 2 Potentiometers and battery level port on ADC1. 2 Potentialmeters are connected to channel 5(PA0) and 6(PA1). (pin10, pin 11) And battery is connected to channel 16(PB1) like below.(pin ...
The STM32L431 RM is ambiguous about being able to use fast flash programming with page erase.In the paragraph on Fast Programming the RM first refers to pages--"This mode allows to program a row (32 double word) and to reduce the page programming ......
Hi All,I have a STM32H7 master communicating with I2C to 4 STM32F0 slaves. The I2C uses DMA but intermittently stalls when the master is transmitting to a slave. It sends the address and the first data byte successfully (acknowledged), but then fai...
In UM1718, it states that IPCC is only used for the STM32MP1 series.I understand that I need to update the version that I'm using however, I do not want to loose and have to restart again for our project. Furthermore, I've tried to use the H747 and o...

Hello,I am trying to get information from two analog sensore (FSRs) by using two seperated data lines (PB0 as IN15 and PA7 as IN12) through ADC1(Not important note - I created unint32s for debuging and I am willing to transfer the data by using CANBU...
Hello everyone,I am using an STM32H723ZG MCU and wanted to use ADC scan conversion with DMA. I could implement what I wanted there is just one thing I do not fully understand related to it.I am using ADC3 whose maximal resolution is 12 bit. Based on ...
