Hello, I have a custom board with the F413ZH controller on it. For retaining RTC information after power loss, I have connected a 3.3V coin cell and a 32.768 khz crystal on LSE. However, I am facing issues with the Backup registers on the software si...
Hi,For a project I'm working on I need to use the HRTIM timer. This is atimer I haven't used before and I can’t seem to get theHAL_HRTIM_Compare1EventCallback to trigger. The ‘normal’HAL_HRTIM_RepetitionEventCallback works so the timer runs (tested W...
Dear ST experts,Our customer in China needs our support to program ST FST1BA59Y(BGA87) chip, but HI-LO RD can’t get the corresponding programming specification and suggestive circuit diagram of program/read mode. We deeply appreciate that you can hel...
I use timer 6 with stm32F7 MCU. The project is generated with CubeMx.Here are the initialize function:static void MX_TIM7_Init(void) { TIM_MasterConfigTypeDef sMasterConfig = {0}; htim7.Instance = TIM7; htim7.Init.Prescaler = 0; htim7.Init.Co...
Here my simple code to use the encoder on STM32F746.I have used the PI2 and PI3 of the STM32F746G-DISCO for input and volume control on an external DAC.Probably someone could reduce the lines of code and obtain the same result.unsigned int Enc_dir;...
I have an STM32F765 Master attached to 7 STM32F411 Slave processors on Half Duplex RS485 bus. The slave processors are in Address Mark mode. They are normally MUTE, until they receive their matching address.Is it true that the BREAK FRAME gets recogn...
stm32f4 discovery keil 5.28 in debug mode getting "cannot evaluate" when I define global variable(like this uint8_t random) and sometimes getting wrong value even if the variable is set to 0 (like uint8_t dds=0). WHAT`s the problem?
Hello everybody, I want to design an application with RTC, I was very impressive with the accurate of DS3231 with small deviation for long time working.But the chip DS3231 is quite large meanwhile RTC is already integrated in STM32 also. I just want ...
I'm using STM32G441KBTx and currently have PB4 as an input and PA10 as a separate output.First, if I put only the microcontroller and programming header, put PB4 as an input with a pullup, and configured PA10 as an output. This is what my main looks ...
Hello. There is no CAN Tx/Rx example ? Where to find it for NUCLEO-F091RC board ?
