I use HAL to go to STOP mode with interrupt (WFI), but the microcontroller immediately exits stop mode.I have LPTIM setup with HAL_LPTIM_Counter_Start_IT() to give interrupt after a few seconds, but even without setting up LPTIM I can't get the micro...
Hi AllI have been experimenting with the Flash write protection most of the day and was hoping to be able to set it by just writing the setting in the FLASH_OPTCR register, however the value that is written doesn't seem to affect anything unless comm...
In Stm32 has too many parameters, So please some explain me how to use this ?. please watch my timer videos. because I know how to use the timer in PIC, but in stm32 which is prescalar and how to calculate for generating pulse(in expected frequency)
I have been using STM32L010K8T6 with a J link debugger. It has been working good for past month or so. But now whenever I use a breakpoint the system does not stop at that particular break point or sometimes does not reach the break point at all. I t...
Greetings all,I'm using the HAL libs to set a couple of pins for ADC use (one-shot).Later on during fw execution, i need to flip some of these pins back to normal GPIO mode.How do I do this?I've been looking over the programming manual, and HAL/LL li...
as it requires i2c communication with repeatative restart the sequence, I am unable to get expected responce from IC
Hello. Please tell us how the microcontroller programming process works. The controller can be programmed in two ways, fill the firmware through the bootloader and through the programmer.If in the first case there is microcode on the controller that ...
I am using memory mapped mode of the QSPI peripheral on an STM32L452. I can see in the memory view at address 0x90000000 the bytes i expect. However, when dereferencing the pointer to that memory all i get is 0xFF's. In the attached photo you can see...
I have many problems using the CN7 connector (pin SDA/SCL) with external I2C FRAM and I2C DAC chip.There are no problem using the EXT/RF E2P connector (pin EXT_SDA/EXT_SCL).Why ?
