Hi,The LSI clock speed changes by 200..300Hz when the voltage regulator switches (ie., when the MCU enters stop 1 mode). Since I calibrate this clock to the 32MHz HSE in running mode (with the normal voltage regulator), it causes an inaccuracy in sto...
Hi community,I'm trying to launch an ANN on this discovery board.I build and programm both CM without error.However I'm not able to debug CM4 and have this error :Starting server with the following options: Persistent Mode : Disabled Loggi...
Hi. I'm designing a battery powered device that use 1.8V for the MCU core and 3V for VDDA to drive the opamps and comparators. I would like to use the output of an opamp / comparator to power a small sensor at 3V- enabling me to switch it on/off v...
Hello,I am using STM32CubeIDe V1.10.0.my project is structured as follows:-CubeMX inits-HAL_I2C_IsDeviceReady-HAL_I2C_Mem_Read //Read a large amount from an I2C EEPROM-while(1)I have now done a lot of troubleshooting to understand why HAL_I2C_IsDevic...
Posted on June 23, 2018 at 23:02I just start to create a driver for SST26VF064B Serial Flash in QSPI mode.Anyone knows where I may able to get an example using the HAL layer QSPI driver ?
I am working with Discovery kit with STM32U5A9NJ MCU (MB1829) and I am trying to implement code to read and write the PSRAM (APS512XXN-OBRx DDR Octal SPI PSRAM) in memory mapped mode.All GPIOs are properly configured. (I used MXCube)The configuration...
Hi,I have an STM32L0538 discovery board and I'm trying the Demo example. The problem is that it does not work. When I flash the board it changes the e-ink display like this:Also when I touch the bottom bar it does nothing. The revision of the board i...
A novice HAL programmer responded with this image:I did not find any extended information on the HAL_I2C_Master_Transmit function.There are a lot of incorrect codes on the Internet with this function, there are even videos on YouTube with the incorre...

Hello, I am brand new to all of this flashing firmware and stuff, I'm trying to find a way to get the firmware from a shark AV751 I just took apart with an STM32F071 to possibly make a custom app and add mapping? I know I am jumping from step 1 to st...
