Hello,I learned to blink a led as well as using the user's button to make interrupt using HAL library and CubeMXHowever I learnt that through tutorials.I tried to learn more thanks to the datasheet but it doesn't really help. For instance, the ReadPi...
Hello,i interface the STEVAL-IDP005V1 with STM32F401RE programmer (ST-LINK V2-1) with needed connections so when i drop the .bin into drive no errors come but the device resets and it doesnt show any parameters on serial display. i follow the attac...
Hello,I am a bit confused with how to declare external nor flash (FMC) through MPU.I am using the external flash as following:program the application into the external flashbootloader starts in intrernal flash, and then run the application from exter...
As some of you have noticed in previous questions, I have a rather unique problem in that my code has to be modifiable by the end-user, who is more of a hacker than computer expert, can usually handle a PC so can use something like Arduino but may no...
Hello All,Currently, we are working on STM32F030C6T6TR controller, it has 32KB flash memory & this memory is not sufficient for our application.We do not have sufficient time to design the PCB again. Please suggest any other controller with the large...
Hi there.I was making some tests and I have observed that, when I shortcircuit 3V3 into my analog pin (in this case PA0), the reading I'm having is 4022 instead of 4095.Why this difference? I'm using HAL libraries as follows://Function to obtain ADC ...
Hello everyone !I'm new here and i wanted to know how these lines say please??I wanted to have microsecond delay for my ultrasonic sensor.Thanks for all your help!void usDelay(uint32_t uSec) { if(uSec < 2) uSec = 2; usTIM->ARR = uSec - 1; usTIM-...
I'm trying to move an array from DTCM to SRAM1.So I use MDMA in as memery to memory config. It isn't my first time I got it running, but never used it to transfer data from/to TCM region.I want to copy array at 0x20000018 starting address (DTCM regio...
I have bought STM32L063C8U6 (version in UFQFPN 48 package) but I can not find pinout in datasheet. DS10090 version 7 does not mention any UFQFPN package.Also SMTCubeMX says that "cannot load this MCU). Is this version secret?Thanks for answer, Jiří ...
