hello friends)))) I bought a new stm32H743 for familiarization and got confused how to implement PWM on HRTIM. I'm trying to do PWM on timer B. configured GPIO_PC8 to AF1 in GPIOx_AFRH. everything is fine there.HRTIM_B_PERxR==2000 HRTIM_B_CMP1xR==200...
I am working on a state machine to control a stm32f334 mcu, first state would be general initialization, the wifi initialization, waiting for stable input and some other states that are not relevant here. It was working smoothly and I wanted to commi...
Hi, I would like to re-program only some higher part of flash memory with In-Application-Programming (Chip: STM32G491 - this in RefMan is defined as "Flash category 4" device).My normal firmware e. g. is running in lower 256kB Flash.And now I want to...
Hi,I'm working with STM32F439ZI MCU. I setted system clock 180 MHz and as Reference Manual (RM0090) says I did:-- VOS[1:0] = 0x11-- over drive mode enabling-- 5 WS latency (6 CPU cycles)When I try to program something the first time after power up, i...
Using something like STLink util or newer, command line software: Can one identify which type of STM32 MCU is connected? E.g. for use in further scripts. It doesn't help if I see it on a GUI somewhere.
Hello Support Team,Please find the below issue description along with the attached code. Please suggest how we can fix this issue. I have developed the SPI with DMA code for STM32H745-DISC (Discovery board). I have flashed master code on the first bo...
For my application I'm using a comparator and i have set a reference voltage(threshold) for that and my application is that, if the current passes through the threshold then my comparator output should be turn on(1 or 0). I have set the comparator ou...
I'm trying to implement SPI Full Duplex communication in NUCLEO-H745ZI-Q board by configuring CM7 as Master & CM4 as slave. I used the function HAL_SPI_TransmitReceive() in both the cores but could not get the expected result.I tried to debug and fou...
Hello!I'm receiving data in UART Rx with DMA and I need to make it inmunne to disconnections. Now, sometimes I can recover the communication after a disconnection, but I need it always.Using the debugger I realized that huart1.ErrorCode change its va...
