Enquiry on MCU Availability and its Technical document

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 ...

Measuring battery level by ADC, but level is changing by other adc channel

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 ...

STM32L431: Does fast flash programming only work for bank erase?

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 ......

Resolved! I2C using DMA intermittently stalls

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...
