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 ?
Hi everyone. I'm a novice so have patience with me. I have a stm32f103c8 (blue phill) card connected to 8 HC-SR04 ultrasonic sensors. I use the STM32Cube IDE. I already have the program ready to read the distances in all the ultrasonic sensors. Now I...
Arm_correlate_fast_q31 takes almost twice as much time as arm_correlate_q31.Am i missing something? I measured the calculating time for arm_correlate_q31 for various block sizes and then simply inserted the "fast_" in the function call and it takes a...
I wanted to generate PWM Waveforms with nucleo F411and found a severe bug in the hardware. Maybe it is described in the errata sheet, but I found nothing.bug:DMA is dependent on data send on DMA stream. Sometimes DMA transfer is not done. (DMA circul...
