Hello,I use the STM32F767 microprocessor on my PCB design. After sending back the converted data to a PC with UART, I got strange characters (in Picture1). Normally, I am supposed to get the numbers like in Picture2. The characters look like Chinese ...
I am using the stm32h745-Discovery board.I am getting the data using the interrupt method and polling method but am not able to get the Data using the uart_receive_DMA. …What are the further configurations needed for the DMA and What else to do get ...
Hello,I have a timer TIM2 interrupting every 2ms (that's working).When I receive SPI data from SPI3_IRQHandler, I want to launch the interrupt of this timer TIM2_IRQHandler as soon as possible (eg in the next 10us).Then, the timer will continue to in...
MIFEN explanation would use some rewording, too...JW
Hello,It's not clear for me what a peripheral reset (registers RCC_xxxRSTR) is doing. I didn't find the details in the reference manual. I assume it resets the internal state machine of the periph, its FIFOs, but for example does it also reset its co...
I'm trying to program the option bytes on an STM32G0B1 but it keeps timing out at the end of the program sequence and never actually succeeds, no matter how many times I try.I enable the Flash peripheralI (successfully) unlock the flashI (successfull...
In my application I want to use timer to turn on LED for around 300ms and simultaneously generate PWM signal of freq 2.7kHz (for buzzer) on PA10 pin. Is there any way I can achieve this?(NOTE: I have already used TIM2 and TIM21 timers. TIM21 is also ...
Hi,I am using stm32f1 and HUT21D sensor (Temperature and humidity sensor). The sensor use i2c for communication. I am using IAR and cubeMX.For cube: I used default setting for i2c.For IAR: I shared the main.c below.Can anyone help on why only get 0.#...
HI i got a problèm on an stm32f0.after a reset the µC is at 8mhz but i'm only able to climb to 16mhz when i want to go to 48MHZ , did someone have idea of where does the problem come from.the µc are not new because i work on protoboard and i cant cha...
