- Pull-up and pull-down technology in microcontrollers
Hello everyone, I am making measurements for the characterization of pull-up and pull-down resistances in microcontrollers GPIO interface I am currently working on a STM32 microcontroller, and in particular the STM32F103C8T6 A ST Microelectronics employee on the ST Microelectronics forum told
- how to write and read external SRAM in stm32F103
Hello friends, I am doing a project around stm32f103, where i need to load the hex file from remote server using wifi module What i did is, my device had less RAM so i connected an external SRAM so that i can dump the incoming hex file (size =60k) directly to the external sram and than to SD card later to the flash
- STM32f103 is not working Blink Led Project on Proteus simulation but . . .
My first stm project Blinky Led works on real Hardware (BluePill Board) ,BUt not working on Proteus Simulation Whats the wrong with I ?
- PDM vs PWM and stm32f103 - Forum for Electronics
Hello everyone, although I researched, I could not understand the difference between PDM (pulse densty modulation) and PWM (pulse width modulation) in practice PDM: The analog modulation type in which the carrier signal pulse width changes according to the modulation signal There is no change
- [SOLVED] - STM32f103 wont start | Forum for Electronics
Hello, I designed a simple board based on STM32F103 and produce some of them and all of them work fine In my new design I use PB4 and PA8 pins but other parts of my circuit is the same as the old one However, the old program doesn't work properly( I can program my MCU correctly (it verifies my
- Learning STM32 + LCD Interfacing code not working
Hello I am trying to interface 4 bit LCD (16x2 ) with STM32f103 controller its not working whats the wrong with me The main c code is attached here with
- [SOLVED] - Can I write a 8 bit or 16 bit Data to the outport of the . . .
I am using STM32F103 ,CUBE IDE with HAL library , I am trying to write the outport as giving a 4 bit value to the entire port (16bit ) By using a shift bit operator
- Clean power supply for RTC - Forum for Electronics
I connected the VBAT pin of STM32F103 directly to the battery and since datasheet said that no CAP should be added to vbat pin if there is a battery since the leakagae current of CAP will be roughly of the order of current in vbat pin, so it will have shorten the battery life
