Hello, we have boards with the MCU STM32F746. This works normally but in two cases we had a problem with the option bytes. Several values were changed and now we can't remove the protection.The first board we tried several times to change level prote...
Doing my due diligence, I did find someone else asked the question in 2019 but there was no response.https://community.st.com/s/feed/0D50X0000BaM9PoSQK?t=1669134764953What it did show was the equation, but not where he found it, and no description of...
I wish everyone good work.First of all, sorry for my bad english.I would like to talk about the problem I had with my STM32F407.There are 3 programs running on my system.These:* Bootloader 1 (Updates the bootloader 2.) load region = 0x08000000 size_...
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...
