The hardfault exception often occurs during system operation.The R14(LR) is 0xFFFFFFF9 in the exception handler(bit2 = 0).So the main stack(MSP) is used, and that value is 0x20003778 like the follwing picture.The following picture is the memory valu...
Hello I need to read the voltage where I connected ADC to the voltage divider. I have a code of ATmega where I need it to convert to HAL code. Can you please suggest me how?here's the code:void readVcc(byte ATR[]) { ADCSRA |= _BV(ADSC); // Convert...
I'm building a computationally demanding application on a STMF2F769DI board using STM32CubeIDE and a USB connection to debug.I've wrapped a segment of code (a FIR downsampling filter) with LED on/off and measured its execution time on an oscillosccop...
Hi, I'm using STM32F103CBU6TR and I can't find the thermal resistance (j-C).BRShmuel
Hi,I am using STM32F303CBT6 MCU and WEO004864AWPP3N00000 OLED.Problem :Imagine, the black color shape is an actual OLED display, If I am showing something in the display. It is shown in the red color shapes. Once I scroll the display, only I can see ...
Hello.I try to use ADC with STM32H743II. The problem is that the calibration flag is not reset.//ADC1 RCC->AHB1ENR |= RCC_AHB1ENR_ADC12EN; //Exit DEEP Sleep ADC1->CR = 0; while(ADC1->CR != 0) { ADC1->CR = 0; }; //Enable LDO ADC1->CR = ADC_CR_A...
Can I use STM32F411RE to learn DSP programming? Please advise!
I use CMSIS to write program that transfer data from SD card through SDIO. For my task i need 4bit mode, but it isn't working. When i try to read some block from SD card STBITERR bit in SDIO_STA register goes high, that means that start bit hasn't be...
