Hi I am using the STM23G051C8T6 for the internal RTC and an external battery on Vbat. I noticed if I perform the Calibration using the following lineHAL_ADCEx_Calibration_Start(&hadc1);my initial ADC reading will be lower then actual reading. For exa...
Hopefully someone at STE cares enough to take this honest feedback on board...My project had to move from atmel to something with more performance. I settled on STM32.The experience has been terrible due to sub-optimal documentation from STE, relyin...
I am using the HAL library with an STM32L07xx processor. To keep things simple, I have implemented master transfers on the I2C bus in the polling IO mode. Most of the time it seems to work, however once in a while a master transmit seems to get lost....
Hi,I am new to STM32 devices. I have a STM32F407 Discovery 1 board.I wanted to generate a 1 KHZ signal with a 50% duty cycle.The timer clock is configured to 84 MHZI am using TIM3 on channel 4. The prescaler is 210 and the counter period is 400 =>840...
Hi,In the Datasheet there is only a diagram for the ADC in single-ended mode.What is the circuit for differential mode:For instance, does it re-use the same capacitor across the two inputs or does it use two capacitors, one for each input?ThanksAlex
Hi, I have an STM32L4x6 processor.I'm reading data using ADC and DMA, and after the HAL_ADC_ConvCpltCallback, I process the data with a Fast Fourier Transform. Originally, in bare-metal, I had a flag in the main loop, and when the interrupt occurred,...
Posted on December 15, 2014 at 22:02I'm working on a project that has an on-board SD card and a USB port. I'd like to figure out how to connect the SD card to the USB as a mass storage device. Does anyone have any experience doing this and can provi...
Hi ST Team,We have an issue concerning a PWM generation.We have a MCU : STM32F303 driving directly the LM25101 driver from Texas instrument with no limiting resistor or other protection on it.The PWM drives two mosfet legs with 2 mosfet configured as...
I would like to build a 5-button remote (RF 868 Mhz) and was thinking of using the STM32G031F6(The RF is provided using an external chip, similar to Si4455)However the STM32G031F6 has only 4 x SYS_WAKEUP pins.Is there anyway to wake up from standby u...
Hi I need to start unit testing for a STM32 project in C how can I start a the testing, Can any one send some reference for STM32 cube IDE based Unit Testing method
