I'm using the stm32f103 and I'm trying to send a text stored in SRAM via DMA to the USART 2 peripheral. My assumption is I'll turn on the usart2 TX dma ( DMAT )request whenever I need it and turn it off after the current transmission completes, (i.e...
I have managed to get ADC working in Interrupt mode and can read the three sensors values into a buffer called ADC3_VALUES[] on each of 3 callback events triggered by the ADC..../* USER CODE BEGIN 1 */void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* ...
Hi, does input frequency have effect on the smooth digital calibration period since in the documentation(screenshot attached) it says the calibration is performed during a cycle of 2 to the power of 20 which amounts to frequency of 32.768 x 32 . Does...
Hi,I've been coding for telnet console using API KEIL offer.I'm working on Telnet_Server_UIF.CPP which was created by example installer of KEIL.i can get strings via netTELNETs_ProcessCommand call back. this only gives me strings after hitting enter...
Hi.yesterday, my stm32 board run was good.today, I add to code(printf...). but my board is hangup.I was check memory over. but, i use 25%.project.map 177 901 bytes of readonly code memory 54 396 bytes of readonly data memory 87 330 bytes of...
I am using the arm pid library and I do not know how to use the arm_pid_q31 call. I need to give it an error as a q31_t, however, I am not entirely sure how to go from an int32_t to a q31_t. Do I need to normalize the in32_t to a value between -1 and...
I am using STM32L0Configured PA.0 as syswkup pin in cubemxBut i want to use it as gpio input for a push button while running the microcontroller and send it to standby mode.And while in sleep ,want to use same button to wakeit upIs it possible ?How t...
I have been driving CCD/CMOS linear arrays using PIC24s and have exceeded this processors 64mHz capability so i am seeking something much faster. I see that the STM32H7 MCU has a 480mHz clock and thought I would give it a try. It is a little uncl...
