Could UART function on lines with 10nF capacitance?
I am using all of the pins of a STM32L471RE in a design.In manufacturing, there is the need to communicate with the MCU over UART (during Functional Testing (FCT)). The problem is that all the pins are taken, so there are no free UART ports available...
Save a variable to flash memory, and restore variable later after power loss?
Posted on April 11, 2018 at 23:02Hello, I was wondering if its possible to save a variable to flash memory, so that after power down or reset, I could then restore that variable?The specific chip I am using is the STM32F303CCT6 and the STM32F301C6, ...
Memory mapped mode write sizes for PSRAM APS6408L on B-U858I-IOT02A Discovery Kit
@Alex - APMemory I am trying interface APS6408L on the B-U858I-IOT02A Discovery Kit in OSPI DTR memory mapped mode for both read and writes. The datasheet for APS6408L mentions that the page size for it is 1Kb. In the memory mapped mode, is it possi...
Ho to add own piece of code in to the make file?
It's possible to add my own piece of code to the make file? I'm asking because I've already tried to add it, but after clicking the "Build" button, my code disappears!PS - I want to add "Generate packed filesystem for serving Web UI".
Custom usb
Hi Team, I'm using STM32H743 series controller.I want to implement USB Base class on STM32H743. Unfortunately CubeMX will not support it.Any example code which works on Base class- 00h, Sub class -00h and protocol -00h
Resolved! STM32G050C8T6 ADC_IN11: inconsistency in the datasheet?
Hello,According to the datasheet PB7 can be used as ADC_IN11.Is this an error in datasheet? ADC_IN11 is already used by PB10 and cubeMX doesn't seem to allow me to use PB7 or to remap this pin. How can I use ADC_IN11 on pin PB7 as mentioned in datas...
STM32H747I JPEG DecodeDMA
Hi all,I´m new to STM32 and just recently bought an STM32H747I-DISCO. I needed one with a touch screen for a project. I was going thru the examples and got the LCD DSI SingleBuffer to work but was having problems with the JPEGDecodeFromFLASH DMA. I u...
STM32L4A6 reading OK but writing failed "error erase memory"
Hi everyone,I'm getting stucked with a programming issue.I try to load a HEX file into a STM32L4A6 chip on a BMS board.I've checked the wiring of the st-link/v2 programmer and everything is OK.The chip can be read from the CUBE software but when i wa...
IEC60335 SelfTestLib
In our legacy STM32f103 project a ST library named "Self Test Library" is used. It has version 1.0, dated 10/01/2007. That library is certified according to IEC60335. I found it in an archive named IEC60335.zip, but I have no idea if that's the origi...
