hi ，I have some problms about FMC-SRAM with own r&d board based on stm32h750，hope someone give me some hlps�? Now we have a strange problem that we operate on an external 16-bit bus. If we just write a word (16-bit) that is 2 bytes, the actual bus op...
I am using St microcontroller( STM32F030C6). In my project I am using ADC to measure voltage and current values. Also we are triggering DMA interrupt once the ADC conversion finish for multiple channels. Once we receive the interrupt we disble DMA an...
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 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.
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 ...
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...
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 ...
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
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...
