Hi all,I'm trying to execute some code in interrupt mode (blinking a LED) while the MCU (STM32H725) is erasing a flash sector (obviously that is not used by the application). I've moved the vector table to RAM (0x240000000) and also the ISR function,...
Ever time, I mean EVERY time I read an interesting link from ST about new tech, EVERYTIME it links to a product nobody has in stock, there are no reference designs, no support, no stock, no evaluation kits.This is such an inefficient way to operate a...
Hello,I have one master and multiple slave devices for I2C Connections.So, my Query is that;I am connecting series resistors after the Pull up Resistors on SDA SCL lines,Now the query is that should I connect those Series Resistors at only Master sid...
Hi fellows,I have a board with STM32F407ZGT6. But today the board stoped wihtout any reason, and when I open the STM32 Cube promgrammer using ST-Link V2, I can see the STM32407, the version, the size, so the chip is apparently fine, but I can't donlo...
So the datasheet says "Min VREF+ Positive reference voltage - 1.8 V (1)(2)(3)", and note 3: VDDA -VREF+ < 1.2 V, so with VDDA at 2.925v, VREF of 1.755V would be permitted? Its a bit confusing to me at this point!Given the ADC 12 bit resolution, the L...
I made a simple program on an ESP32 to send dummy data with something like this $DUMMYDATA,0,1I've tried using another ESP32 as a receiver and it works perfectly. My goals is implement the same thing to my STM32F103C8T6. Here's my code for the first ...
Hi All,I'm working on a STM32H7 custom board and I'm trying to access a Cypress S70KL HyperRam through the Hyperbus protocol using the OCTOSPI1. I'm able to access in read/write the HyperRam but I want to use the delay block therefore in CubeMx I ena...
What is the role of syscalls.c file in GNU ARM(STM32 for instance) based projects? I found 2 ways of successfully building the project1. Delete syscalls.c and include -specs=nosys.specs in the linker flags2. Simply include syscalls.cWhat is the funda...
Hello again everybody. I have run into the following problem: I try calibrate the ADC1 and plain calibration seems to work just fine (apparently), but as soon as I try to follow the Extended Calibration procedure, described on page 1007 of the Holy U...
