We are facing data loss issue while ping test was conducted on the STM32F407 with lwip stack 1.4.1 The stack was downloaded for STM32F407 Evaluation Board Code from www.st.com site after changing pin configuration [used tftpserver standalone code] f...
Hi, i want to try adc ch0 and ch1 in stm32f053 nucleo, i have 10k ohm and 1k ohm between 3v3, gnd and analog input. ( Basically voltage divider for measure.) However, i've faced absurd values in adc channel and, these values never changes. I'm sharin...
Hi i want to enable pwm output on PA10, as in below code, will do necessary init by MX_TIM1_Init, and then call HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_3); to start.but PA10 is kept low measured by Osi.could you help review and any suggestion ? thanks...
I have downloaded the temperature sensor capability demo and I cannot get the code to work on the board. The program is stuck in the while loop of RTC_Configuration(). RCC_GetFlagStatus() is returning RESET. Also how do I get the temperature values t...
