Hello,I'm using fatfs by chan with this SD driver http://stm32f4-discovery.net/2014/07/library-21-read-sd-card-fatfs-stm32f4xx-devices/ and with my own SPI driver. I have successfully mounted and opened a file but when I try to write using f_puts, it...
Hello. I'm using an STM32G071KBU6N in a USBPD application. My application uses both internal UCPD ports.I'm working on enabling the DMA and DMAMUX for use with the UCPD peripheral, for both Rx and Tx of both ports. I'm focusing on Tx right now, and c...
Would anyone knows why the STM32F7xxin stm32f7xx_hal_i2c.h structure I2C_HandleTypeDef doesn't have __IO uint32_t Devaddress; /*!< I2C Target device address */ __IO uint32_t Memaddress; /*!< I2C Target memory address */ ...
Hi - I'm trying to get a single PDM mic (ST MP34DT01-M) working with an STM32H7, using SAI. It's outputting static when I send the DAC each SAI *freq* interrupt. Some questions:Is the DFSDM peripheral required? If so, what does the value of the SAI x...
Hi, I'm doing a project currently where I have to use the stm32 to relay data to and from the PC simultaneously. I have two other ICs - an IQ modulator and IQ demodulator. I need to send two time-varying signals simultaneously from the PC to the IQ m...
I'm using the stm32l4 MCU with uCOS-III RTOS. The system frequency = 2MH using the MSI internal clk. I'm using ADC, 2 UART, I2C, SPI. My power consumption is about 700uA. The standby mode works well, enter to standby and wake up from standby. But the...
Hi all,after developing the firmware for a composite USB application (AUDIO + CDC_VCOM) for an STM32F446 device, I'm facing strange behaviour in the driver side for Windows (I've tested both 10 and 8 with the same results) - Linux and MacOs works out...
B1L/B2L vs FLI'm writing an ethernet driver and the FL field in TDES3 seems to not do anything.I am not setting the TSE bit.The packets seem to always leave with a size that is the sum of both B1L and B2L (if used).In my last test I set it up like so...
Hey, I'm currently trying to get myself away from HAL, insteed using a more direct implementation. So the first thing I am trying is a simple blinky programm, with as little as possible number of files. I downloaded the StdPeripherel Files for my boa...
