Hello everyone.I have 2 incremental encoders. One of them has the output voltage of signals A and B 5 volts and the other one 24 volts. I need to count the increments with stm32f4 and timers in the mode encoder. But I have to first convert the 5 and ...
I design a stm32h743 board without conformal coating, it works good, when I shacked board, stm32h743 failed and burnt.what's that reason?thank you
hi i am trying to measure battery voltage with Vrefint channel. it works . when the microcontroller goes to sleep, after waking up, the battery measurements do not work.while (1) {HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1, 100);adc = HA...
Hello ,I will power a stm32 pcb with battery so the vdd voltage will dropSo i need to read this VDD to make a conversion of external temp sensor from 0->4096 to a voltage Voltage temp=(VDD*adc_value/4096)But my chip only have one ADC and i'm unable t...
Hi.I can read and write from nand flash memory with fmc but when is use this function for a test code it mostly returns zero and i think its not ok.addr.Block=1; addr.Page=0; HAL_NAND_ECC_Enable(&hnand1); HAL_NAND_Read_Page(&hnand1, &addr, aRxBuf...
I am programming a output PWM using the timers on this processor. since I am new, I decided to start using the examples for this specific processor found in the folder 'en.stm32cubef3_v1.11.0'As a first instance I execute the project file in the fold...
I find an error in the RM0090(STM32F4 Reference manual) as follows:But I don't know how to report it. Please help me.
I have a code for stm32g070 which configure the adc as continuous conversion mode, sequencer set to fully configurable, scan conversion mode, dma continuous request, end of sequence conversion, oversampling mode right shift to 5 and ratio 32x.Also I ...
I just got an STM32 Nucleo 64 - F411RE.The board has a crystal installed on the debugger, and a crystal oscillator on the board.Do I need to install an external crystal in the provided space X3? and how can I do so?It's my first time using STM32 I do...
