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...
I´m currently working on an Application using the "new" G431 µC. At first i had massive Problems getting it to not crash (Several Hardfaults occuring here) randomly after ~100 instructions (not timing related...). After a while my good friend the rea...
Hi. I have encountered problem during pushing program to my nucleo board. I use STM32L432KC and it doesn't work there. Therefore i have also borrow STM32L011K4 and it seems that there everything works well on this borad. I am completly beginner in ST...
Hello,I am working on NUCLEO-H745ZIQ board. I am interfacing PCAL6524 to board .I have to read the Device address of that IC. Which HAL function that I have to used? I am get confused.
