STM32G473VET6 Default pin configurations
As i red from reference manual most of the pins are in analog mode and pins are configured as per reset value of GPIOx_MODE/GPIOx_PUPDR/...so many other register but i want to know which pins function have assigned to individual pins.
Resolved! Floating point conversion in STM32f767.
Hello Everyone, I am using STM32F767 and have generated code from STM32CubeMX. I am trying to convert a string of hexadecimal to float value, but it seems that the float is not converting the value. I am using Keil IDE UV5 ,and I have tried setting "...
Resolved! How to use the Basic Timer 6 on STM32F407 MCU.
I have to keep a pin high for a certain amount of time, about 1us, I figured that it probably makes sense to do this with a timer. I was going to use SysTick but I decided that it makes mores sense to learn the timer peripherals.I think I have the co...
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...
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...
Sprintf STM32L4 not work I see just 0
God moorning I trying to view the output of sprintf of float value on the terminal I/O using nucleo stm32L4.I am using IAR. but i see just 0. char pippo_alb[20]; sprintf(pippo_alb,"%g", 27); In ''project options...
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...
