STM32H723xx won't program at 3.3 volts but will program at 3.2 volts

I am using a STM32H723ZGT6 on a small project. The project fails to program when I am using 3.3 volts. It programs just fine at 3.2 volts. Always gives me a fail in final launch sequence. However, it always programs when I apply a small amount of...

UART escape sequences? NUCLEO-U575ZI

Hello everybody! I want to implement a simple UART debug/diagnose tool for my application, using UART on NUCLEO-U575ZI -> Termite or whatever other PC terminal program. Could please someone help me with a link to a list of escape sequences that I ca...

ADC DMA not updating all channels

I'm using an STM32L4S9 MCU and I'm having trouble getting all the channels to update after starting ​HAL_ADC_Start_DMA. I'm doing a regular 12 bit conversion on 5 channels, trigger by software, waiting for conversion completed in the adc call back ...

I'm working on ADC (12 bit) in NUCLEO-L4P5ZG board. In that the ADC value is correctly showing Upto ADC_IN_10 channel, afterwards it is showing random values for channel 11-15 what might be the reason?

Optimizing ADC DMA transfert and IRQ latency

Hello,I have the following config:STM32H743- Core 400MHz- AXI/AHB 200MHz- ADC clocked by the PLL at 144MHz, then divided by 4 (async mode) => 36MHz- TIM15 trigering ADC conversionsADC1 in scan mode converting 2 channels in scan mode. Data sent to SRA...

Implementation of a STM32 in transparent mode to flash another UART-connected STM32. What UART configurations and timing should be setting to implement this feature in STM32 in transparent mode?

I have one Master STM32 connected over UART to a Linux MPU and also connected over another UART to a Slave STM32.My purpose is to set the Slave STM32 in bootloader and flash from the MPU the application in the Slave STM32, the Master STM32 is in the ...

Using STM32H743 I2C, with CR2 RELOAD and NBYTES=0 gives TC interrupt instead of TCR.

I have to port an existing I2C API to the STM32H743 using the LL drivers. One of the functions must perform the START, issue the address of the slave, then return control. Then another function will send the data.The fact is that when I initialize th...
