STM32F469 external QSPI loader

Hello, I am trying to create an external loader for N25Q128A QSPI. I'm currently developing on STM32F469I-DISCO. My loader doesn't work once loaded into STM32 ST-LINK utility (nor in CUBE programmer). If I modify my project adding a main file with a ...

I am doing I2C project with [MPU6050][1] using [STM32F4DISCOVERY][2] board. The ADDR bit in SR1 register is clearing in one instruction execution without reading SR2 register. Because of clearing ADDR bit, I can't do acknowledge disable is made during EV6

The datasheet states:>ADDR: Address sent (master mode)/matched (slave mode) This bit is cleared by software reading SR1 register followed reading SR2.In case a single byte has to be received, the Acknowledge disable is made during EV6 (before ADDR fl...

HI ALL. In Our project with STM32F103 we're using FLASH as EEPROM. with reffering to "AN2594 Application note EEPROM emulation in STM32F10x microcontrollers".

in some cases that we encountered, 2 types of failure occur. 1- when powering up, ALL sectors of flash, are Erased. we guess ESD makes all sectors erased. with additional protection in power circuit, this problem solved.2- after powering up, we reali...

Porting code from STM32L151ZD to STM32L151ZE

Hi,I had to port to STM32L151ZE from STM32L151ZD  because of a RAM limitation. The code seems to work as it is, however I am facing issues in SPI communication when the SEGGER J-Link debugger is kept connected to the board. I tried probing the clock ...

measurement of currents using ACS172 on STM32f407VG

Hai , my name is Dattu i am working on a project which involves measurement of current using ADC on STM32f407VG to achieve this i am using a 30A ACS712 sensor i have interfaced the sensor but when i am running the program i am getting a const...

STM32L063x8 - Errata: 2.1.11 "Unexpected system reset when waking up from Stop mode with regulator in low-power mode" problem really fixed?

We have a problem like "2.1.11 Unexpected system reset when waking up from Stop mode withregulator in low-power mode", with chip revision Z, but with revision X too. This error occurs sometimes, even with workaround. Ist this topic completely solved...

Hello! I have to send data from the STM32f103C8 to PC. How can I do it?

STM32G47x Flash layout (dual vs. single bank)

Hello,I'm hoping to get clarification on the dual-bank flash availability in STM32G47x parts with fewer than 512K of FLASH. The datasheets (DS12288 & DS12712) cover the B, C and E flash sizes. The first page refers to "up to 512KB Flash", yet there...

Problem STM32L162RD with STMTOUCH_DRIVER

Hello all, i have a problem with the STMTOUCH_DRIVER to manage a touch button and a slider. I have integrated the library into my code and if i manage only one bank and the touch button all works. In Touch.c and .h there is the init and main function...
