Hi -I am trying to bring up a new design - a 3 phase forward converter, using the HRTIM to fire six gate drives. Under normal design loads it works great, but for normal loading I have the CONT bits set for master and subs. For light loading, I ne...
Hi - I have an application running a 1 kW 500VDC to 25V DC supply for a klystron filament heater. I am using a 3 phase forward converter - each phase driven by a FET half bridge to a transformer primary returning to input mid-point. I drive th...

I'm using STM32H723ZG I want to know if a Timer's update event can trigger SPI transfer without any software interrupts.This is the problem
Hello,I am experiencing an interesting problem on the STM32F303VET:UART1 is used to receive and transmit messages (460800 Baud), DMA1 Channel 4 is used for memory to UART TX buffer transfer, DMA1 Channel 5 for UART RX buffer to memory transfer.Under ...
Hi I am looking into using STM32F446RCTx for my design, which includes 2 x USB FS 2.0 (1 x Host + 1 x Device). Hence need to provide an external HSE. I want to use an Oscillator, meaning I setup the HSE as "Bypass Clock Source" .With this setup I pla...

Hello community,I am running in an issue with the VREFINT calibration value of the ADC.For calculation I use the __LL_ADC_CALC_VREFANALOG_VOLTAGE function from the stm32u0xx_ll_adc.h file and I'm getting wrong values.The Chip is powered with 3.3V and...
Could it be time for ST to reveal such an MCU at the summit in a few weeks? Or maybe a Cortex-M55 that actually have integrated flash or MRAM or similar? (STM32N6 is interesting, but I would like to see flash/MRAM/something else integrated...
When using PLL3Q as input with a frequency of 32MHz for USBPHY I have a RCC_CCIPR1 register initialized at value 0x2a00 when entreing USB_CoreReset function that is not correct (should be 0x2b00).
