Hello,the observed bug is the following.We are using STM32L433RC and generating some code from CubeMX using low-level libraries. We are currently evaluating precision of the hardware clock compensation, when using internal MSI RC oscillator with exte...
Hi all, I am now using STM32F205 w/ STM32cubeIDE & STM32cubeMX to make a project with timers. I find that the timer seems not accuracy. So I make a test code to test it (see attached project). For short, it is just Timer_start() while(1) { if(...
I want to use swv ITM DATA CONSOLE to debug my printf statement. How is the process to enable it? if im using the stm32f302r8
I am currently using the STM32-G070RB.The current problem is that ADC_DMA sometimes works and sometimes doesn't, depending on the Clock Prescaler setting and the SamplingTime setting.I would like to know why ADC_DMA is affected by the Clock Prescaler...
Board : STM32F469II created a project via cubemx. how to use QSPI memory for structure variables. I am struggled for this issue.ThanksD. Manikandan
Can you explain what is the use of these section in .ld file KEEP (*(.init)) in text sectionKEEP (*(.fini)) in text section*(.eh_frame) in text section*(COMMON) in bss sectionand whats the difference b/w*(.rodata) and *(.rodata*) Thanks D.Manikandan
I have STM32L475VC + ISM43362 WIFI Module.Set module, connect to AP.if(ISM43362_Init() == WIFI_STATUS_OK) { USART_SendString(SYS_USART, "WIFI INIT OK\r"); if(WIFI_GetMAC_Address(mac_addr) == WIFI_STATUS_OK) { U...
ALL HI�?I am currently using the RTC function of STM32F103, the external passive 32.768KHz crystal and 20p matching capacitor.The RTC function is configured on the software program, and the RTC has been started. But I can't see 32.768KHz waveform whe...
I understand that any external interrupt on PA13, PB13, PC13, PD14 .. or PI15 will all execute the same ISR:EXTI15_10_IRQHandler(void) { HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_13); } Which calls HAL_GPIO_EXTI_IRQHandler before finally calling th...
Hello,we build a breadboard configuration with 20 LEDs. The LEDs have a current consumption of 20mA per LED. It worked properly. Now I read in the datasheet something about a maximum injection current of 25mA of all I/Os (screenshot is attached). So ...
