I've read a ton of app notes, the STM32H7 reference manual, posts here, and I can't figure out how to have the timer UP event trigger a DMA operation. I'm sure this is obvious to someone with more understanding and could be gleaned from other STM32 m...
I am using USART2 on the G474 processor, and I only want the TXE and RXNE interrupts to fire. To do so, I wrote the following: //Enable/set the TXE and RXNE interrupt bits __HAL_USART_ENABLE_IT(&husart2, USART_IT_TXE); __HAL_USART_ENABLE_IT(&husar...
In the last 2 days I can't get any results using search engine on the website. For instance, when I type in any STM32H743II code there is only a message like in the picture below. The same situation is for any acronyms or Doc Ids. Is it only a proble...
I'd like to use the STM32L4R9ZG microcontroller along with a HyperRAM memory such as the ISSI IS66WVH8M8BLL. I was reading through the ST application note AN5050 "Octo-SPI interface on STM32 microcontrollers" to familiarize myself with the process. O...
HI All,I plan to use STM32L4S7ZITx cpu. I need to work with LCD screen which has parallel interface and connected to FMC. It works fine on demo board but i would like to offload the CPU. But i am not sure if FMC can work with DMA.I checked the follow...
Hello.Is it possible to use hardware SPI with STM32G030J6M6 (SO-8)?SPI1 use PA1 (NRST pin) for CLK without remap possibility.SPI2 also use PA1 (NRST pin) for CLK, but has CLK remap to PC14. In that case no MOSI pin.I try to use SPI1. PA1 configured...
I have bought the IO-link master set P-NUCLEO-IOM01M1 from STM. For some reason, I have to replace Nucleo 446RE board with a new Nucleo 446RE board. Then I have flashed the new board with the Firmware P-NUCLEO-IOM0M1_Software_Package_20180724\Master_...
void init_servo_timer() { u16 tmp_period = 0; u16 CCR1_Val = 0; pulse_num_1ms = 0; pulse_period = (1/((float)pulse_num_1ms)); tmp_period = (u16)(pulse_period * 36000); CCR1_Val = (tmp_period / 2 ); TIM_DeInit(TIM1); ...
i am using stm32f207ve microcontroller ,im receiving continuously data from another controller using 50 buffer using interrupt, after the 50 buffer is filled then again the data not receive in buffer 0 ,what i do now????
