I have a very odd problem. I am using the STM32G473 and have configured the clock to 170MHz. When the code runs it drops to default_handler every time after setting up the clock. Not unusual if there is no ISR or call back set up. However if i set th...
EDIT: Hello, everyone. My code issue seems to have resolved itself after much changing, but I never did find out what was happening. My real question was answered: There are no likely circumstances that a higher-priority interrupt should not pre-e...
Hi, All. I have come across an odd situation in I2C communication between F405 and sensors1) F405 is master. address is 7 Bit2) with 3 slave I2C sensors , address, 22h,35h,78h3) There is no issue to read data from sensors of 22h and 35hbut when comm...
I attended the online STM32H5 workshop on Tuesday last week. We were told that the slides and a code for a free STM32H5 Nucleo board would be emailed to us after the workshop. Almost a week later I have still not received either and email to the ad...
Hello,My aim is to send (from my nucleo board_F103+FTDI) somes ADC value from DMA.Easy...But i would like a frame like that (Windows Software need it):<STX>ADC1;ADC2;ADC3<ETX><CR><LF>I'm able to send data, no more...uint16_t sensor_B =1234; char str[...
Dear eveyone,I' little confuse..I'm trying to send dat over uart from a nucleo board (F103 + FDTI). If a use "normal"method, it's work great.I mean, i receive "1234567890" WITH a new line.uint8_t start [20]= "1234567890 \n\r"; HAL_UART_Transmit(&huar...
Hi all,I'm using STM32L562VETQmy question is:can i delay the reset for about 20ms when pressing the NRST pin ?i want to give LED-Indication for the device reset.in other words, can the reset -that comes from the NRST pin- be delayed for a specific am...
I'm trying to scan 6 channels at a 1 KHz rate. I used Timer 2 to generate 1 mSec trigger pulses for the ADC. I used the 'interrupt mode' to verify timing by pulsing an I/O port pin. I'll use DMA eventually. I setup the ISR to collect 24 samples and s...
I'm trying to program some data into a flash sector but the HAL_FLASH_PROGRAM returnsa value of 10 which maps to pga and pgs error.HAL_FLASH_Unlock(); uint64_t val = (uint64_t)(data->at(i) << 8 | data->at(i + 1) << 8 | data...
