STM32G0 DMA and DMAMUX connections

HiI'm trying to write simple code on STM32G030. I read PM and RM for this uC. I try to find where is written which DMA channel is connected to which DMAMUX. for example DMA has 5 DMA channels numbered from 1 to 5 and DMAMUX has request lines numbere...

Where can I find the source code for the "en.stm324xg-eval_fw" I downloaded from the STM32F407 Eval section in st.com? It only contains the .hex and .dfu images. I would like the project in Cube or System Workbench.

The software is described in UM1492

Fail to read from Ambient Light Sensor OPT3001

Hello,I'm still able to read i2c sensors (such as the TMP75 temperature sensor, the FT6336 touch sensor, and the TCA6424 multiplexer).However it seems I'm not able to read data from OPT3001 ambient light sensor. The code is the followingstatic void ...

Hi, I have a problem with the scatter file

In STM32F407, I get into trouble when I write the scatter file as follows. LR_IROM1 0x08000000 0x00020000 {  ; load region size_region ER_IROM1 0x08000000 0x00020000 { ; load address = execution address  *.o (RESET, +First)  *(InRoot$$Sections)  .ANY...

STM32F407, high current draw on VBAT pin - several problems

Hi, I have a design with STM32F407ZGT6, using lots of stuff - external SRAM, USB, SDIO, USARTs for MIDI in/out, etc. Also I use VBAT to maintain RTC and device settings while it is off.First, I had a problem with high VBAT current (about 1mA) while t...

I'm buying the board from mouser.

Executing the main while loop every 60us

Dear ST Hello,I am implementing an infinite state machine on stm32F409 board and I have an issue.I Have a periodic pwm of 60us triggered. I Want to move all the code to the main while loop from the Interrupt service routine.My objective is to run ea...

Error Sending data to Arduino through UART Communication

Hi, I would like to send a data from my STM32F401CC to Arduino. I have connected Tx to Rx and successfully upload the code to stm32 and Arduino Uno. I don't get the values right, only first four readings, then all the values become random. This is my...
