HeyI work with NUCLEO-H723ZG and I try to work with 3.3V External power supply.I try to connect the board according to the datasheet:and I saw few problems:1. My code is not working. I proggram simple code of blinking. when I work with 5V (external/u...
I am writting unit tests for storing data in Flash. First test pass.Second test checks page erasing. After erasing first 8 bytes of given page are not cleared. However if I comment line 50 test is passing. Why is this happening ?
Hi, I'm designing a low power tilt and shake detection sensor module using the STM32 blue pill board. I'm trying my best to attain the datasheet values of 2-5µA. I have done the following:1) Set all GPIO pins to Analog 2) Disabled all peripherals man...
I'm working on two custom boards using STM32H753 and DP83848 PHY. I have setup TCP communication in this setup with LwIP and RTOS and has been running in properly for the last 1.5 years. Out of the blue, in one of the boards, the TCP connection faile...
Hi everyone,I am currently in the process of developing a board that incorporates an STM32H743VIT and a voltage level shifter (FXMA108BQX) positioned adjacent to it. The objectives are to translate 3.3V logic levels to custom voltage levels (programm...
I am trying to disable TrustZone on my MCU - STM32U5 and i followed the steps as per the instructions given here :https://community.st.com/t5/stm32-mcus/how-to-disable-trustzone-on-stm32u5-series/ta-p/49793After I uncheck the TZEN option byte, I no l...
HiI am reading some ADC value in to the DMA Is there any option indebug mode to see how much times taken to the each read of the ADC values ?
Hello group,The STM32h745 controller is what I'm using in my application,I'm attempting to use several interrupts in a single timer from multiple channels,In my application, we require several interrupts from separate channels on a single timer with ...
Hello people, i want to create 4 different PWM signals that has total period of 100 microseconds and working with %25 duty cycle. My timers are working with 50 MHz Speed but it is not necessary to do so. I need them to be shifted 25 microseconds apar...
Hello everyone,I'm writing to raise awareness of a potential problem with quartz resonators that could affect clock designs.In your AN2867, you provide a formula for calculating the load capacitances of quartz oscillators.The datasheet for the STM32L...
