ADC measurement toggles between correct value and (2^n - 1) every couple readings

I am taking measurements with the ADC1 in an STM32f042C6T6. I poll the temperature channel for examples here, but this problem appears in every channel and regardless of sample time, polling/IT/DMA mode, and clock frequency (AFAICT).Setting up the AD...

I have a stm32f072rb board and i would like to know if it is possible to update its firmware directly from a pendrive with a .hex, .bin, .dfu file or another extension. If f072 cannot do it, is there another option capable of it? Thanks in advance.

I already can update the firmware using uart and usb using the DFUSe Demo and the Usb demonstrator GUI, but i need to make a standalone pendrive updater.

STM32L073RZ SPI 16bit data transition

I want to send 16bit spi. 8bit data is not enough because 10 bits are required.I think (uint16_t) data was the data bits which I want to change.I increased it 00 to FF but the result (SDO: Green) is quite different to what I intend. Please review my ...

STM32L496ZG SAI1 - Wrong SAI1_FS_A

I have to read out a Mems-Mic (SPH0645LM4H-B).The Data Format is I2S, 24-bit, 2’s compliment, MSB first.One Cannel (L/R) needs 32 clocks -> Framlenght = 64Samplerate 48kHz, real 46,875kHz, Clock 3.072MHZ.Seems OK.BUT: the FS-Signal Duty_Cycle is wron...

How to configure DMA with USART for burst mode to to increase data throughput?

Hello,Am using STM32F4 DISC, but could not get clear picture of burst mode setup in st reference manuals or online. I could make DMA work only with datawidth as byte at memory and peripheral side and burst as single for both and inc address selected ...

Vancouver BC event June 13

Hello I saw a Facebook ad for a workshop in Vancouver BC June 13 but when I go to register the website only lists Montreal as a Canadian location​. Is the event still happening? Is so I would like to register .​Brandon​

Could there anybody give me the FIT value of STM32F103RCT6TR at 50°C and 85°C with the linked information like activation energy and confidence level? If no, is there an online FIT calculator? Thanks Torsten Rehwald

STM32F4 USART IRQ Problem

I am using USART2 (with IRQ) of STM32F4 for MIDI Receive (31250 bd, 8 Bit, 1Start/Stop Bit). A MIDI Message has normally 3 Bytes following directly on each other, which gives each Byte a duration of ca. 320us. In 1 of 10-30 events one Byte (always B...

How can I convert few mV AC to precise DC?

i want to convert (0mv - 1000mv AC)signal in to precise dc voltage for input to ADC of STM32 micro-controller for measure ac mains voltage suggest me any ic (single power supply +5V dc) or circuit diagram

I am using UART1 of STM32F407VE in interrupt method. I am checking loopback method.But I am losing some characters . I am using docklight serial monitor to send 20-30 set of characters.I need to store around 255 bytes of data to a buffer.

This is my interrupt handler...void USART1_IRQHandler(void)   { uint8_t data;   HAL_UART_IRQHandler(&huart1); __HAL_UART_CLEAR_FLAG(&huart1, UART_FLAG_RXNE); data = (uint8_t)(huart1.Instance->DR & (uint16_t)0x00FFU); HAL_UART_Transmit(&hua...
