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 ...
Resolved! B-U585I-IOT02A with MX25LM51245G to store and retrieve .bin file using filex and levelx.
Hello ST community,I am developing an application based on B-U585I-IOT02A. In this I am using the MX25LM51245G which is on board NOR flash connected via OCTOSPI. The functionality is to save and retrieve a .bin file from the NOR flash. Please let me ...
Resolved! Weird behavior at HAL_GPIO function. Why the microcontroller is unable to set some pins after execute HAL code assertion statement?
I was running and debugging a part of my application on a stm32F207zg microcontroller.Microcontroller is on a custom PCB that is in validation process.This part of application has to set or clear 16 gpios configured as output.If they are initialized ...
Resolved! How to make a PWM of 13.9ns pulse width with HRTIM?
Hello ST community,I use a STM32F3348 DISCO board (STM32F334C8Tx MCU) and I would like to realize a PWM with a period of 4µs (250 000 Hz) and a pulse width of 13,9ns. I tried first with the TIM1 and then with the HRTIM but in both cases I can't reduc...
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 ...
