STM32F100 Temperatur Sensor with VDDA = 2.8V

​Hi,I am usign the STM32F100RB with VDDA = 2.8V.However when trying to use the internal temperature sensor I can calculate a slove of approx 2mV/K instead of approx 4.1K from the electrical caracteristics.Is there anything different at 2.8V instead o...

Issue in code uploading for the IC STM32F100ZC.

hello, Iam having a issue in uploading the code to STM32F100ZC, I have attached the schematic of SW interface done. Its showing an error that target is not connected. I have done all the possible connections for BOOT0 and BOOT1 pins.Please h...

I am trying to use I2C communication using ST NUCLEO-F030R8 with AT24C64 and modifying code generated by STM32CubeMX. When I use HAL_I2C_IsDeviceReady function it returns HAL_OK but HAL_I2C_Mem_Write or HAL_I2C_Mem_Read function returns error

if(HAL_I2C_IsDeviceReady(&hi2c2,0xA0,10,100)==HAL_OK){ sprintf((char*)TxBuff,"\r\ni2c device ready");}else{ sprintf((char*)TxBuff,"\r\ni2c device fail");}if(HAL_I2C_Mem_Write(&hi2c2,0xA0,mem_add,32,&data_send,1,10)==HAL_OK){ sprintf((char*)TxBuff,"\r...

UART tx stop when I send messages for a long time

I'm using uart fuctions with my board STM32F401RE.I don't use cts, rts (hardware flow control) and any receiving process.So I only transmitt some values to PC but I found that when I send a message constantly, suddenly it stop. I think it's related w...

Install DFU driver on Win7 failed

Posted on August 11, 2015 at 04:28Hi guys,I wanted to test DFU function with my STM32F401 board, and my Win7 has installed DfuSe V3.0.4. After I plug USB to PC, it shows the driver is not corrected, so DfuSe can't recognized the USB device.I searche...

USB CDC -- zero length packets

Posted on May 25, 2016 at 23:27I used stm32cubeMX to generate a CDC project for the stm32f3 discovery board.  After much fussing, I have a pretty stable echo going.  If I use a program to generate output/input from the host, I'm finding writes of 64...

Issue with using internal opamp on the STM32L4

Hi I have been reading an ST presentation regarding using the internal opamp on a STM32L433. Am I reading it correctly, this saves in having to use an external opamp? I want to use it for as a follower for the analogue input. I am not sure I am read...

can we run multiple applications same time on stm32

Hi, I want to run DSP lowpass filter and also run other applications like voice over ble and touch screen interrupts at the same time. running one after the other is not efficient.Is there a way to run these applications in parallel on a stm32 proces...
