Hi everyone, first time using freeRTOS and everything is working besides context switching from an ISR.The STM32H743ZI has DMA (DMA1_Stream0) setup as UART Rx. This triggers an ISR that sends a queue for task synchronization, as the task that receive...
I have a problem with the mbedtls server (stm32+lwip) send wrong length message. I am using this code in my project. https://github.com/straight-coding/straight-httpd-lwip-mbedtls-simulator
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...
