Resolved! How to power on a STM32H750VBTx bare chip?

Greetings,I made myself a 100-pin LQFP breakout board and soldered a STM32H750VBT6 to it. I connected all the Vss and all the Vdd. When I try to hook up SWDIO, SWCLK, 3.3V and GND from my ST-Link nothing works. The ST-Link doesn't recognize the micro...

Resolved! SRAM2 parity checking.

I am using an STM32L452CE. I copy an executable (.bin) from Flash to SRAM2. I zero out the remaining SRAM2. I then 'jump' to the executable now in SRAM2. When I have the parity error checking off (FLASH_OPTR_SRAM2_PE = 1) it works fine. When I turn i...

Resolved! Where can I find a list of register names for ST32?

I recently changed the chip i'm using for a project. I'm trying to port code between an STM32F031K6 and an STM32L412K8 but some of the registers seems to be called different things. In particular any reference toADC1->CHSELR doesn't work. Where can I...

Using I2S on IT with STM32F407, I observe that the SPI_I2S IT asserting rate is not the audio sampling rate.

The IT asserting rate seems to be totally de-correlated with the rate of reception of a sample from the microphone.Has somebody already used a microphone MEMS I2S ICS-43434 by InvenSense-TDK ?I don't succeed to connect a stereo pair of this microphon...

STM32G030F6 I2C2 set to slave mode, it can not work fine.

I am newer in STM32G030 develop.I tried to set STM32G030F6 I2C2 slave mode with PC.Q1.Using "HAL_I2C_Slave_Transmit(); it seems Master (PC) read 8 bytes later and stop. The other data will not read.Q2. If used HAL_I2C_Slave_Transmit_IT(), It only wr...

Resolved! STM32L412KB clock options

Im using a STM32L412KB for the first time and Im a little confused about the clock options. I can't seem to change the clock speed (input frequency) in cubeIDE, it's always stuck on 8MHz. However I notice there is an internal oscillator - does this m...
