Hello Community :), I'm using the I2C of the STM32F302:I2C configuration:7 bit data standard mode "100 KHz"mode pollingWhen initiating communication between the STM32 and the sensor, the "HAL_I2C_Master_Transmit" function returns "HAL_ERROR." Upon in...
Hello, I have a problem with my NUCLEO H503RB. I'm trying to make it work with Pmod I2S2 module (ADC+DAC). For now I've connected only ADC via I2S1. This is my HW configuration: I2S config: GPDMA config: Code: No data stored: As you can see, I...
I' m using ADC2(with 4 channel ) and ADC3 (with 2 CHANNEL) i need them to measur current from 6 sensor ACS712 the process was fine with DMA and works pretty good, but the problem is with the while loop. the while loop never runs. i found some tuto...
The STM32CubeMX tool (I'm using 6.10.0) continuously hangs after GENERATE CODE on "Generating user source code..."The STMCubeMX.log file (within the .stm32cubemx directory) shows a java.lang.NullPointerException: 2024-02-13 13:36:22,290 [ERROR] CodeE...
Posted on October 09, 2016 at 23:26What is the best way to restart a DMA servicing a UART using the HAL drivers?On the first iteration the DMA works correctly; transfers new data and fires interrupt.On second iteration, the DMA transfers only one ne...
Hello,I am working on a sensor device acting as a SPI slave with transmit only and without chip select signal. I am using a STM32G070 microcontroller.I configured 4 bytes transmissions using DMA. The problem I have is that the external master can per...
We work with STM32F070RBT6 . There is an internal POR/PDR controller in microcontroller but it seems to be active when VDD below 1.8V according to the product datasheet but the operating voltage seems between 2.4V to 3.6 V.In Run Mode, If the input v...
Hello I hope you can help.We have developed a production programming solution for the range of STM32G474 devices which uses our own hardware controller interface.Is it possible to replicate the "run after programming" --go command externally?(eg, wit...
Hello, I'm experiencing a problem with PB6 pin on STM32G474 MCU when any type of reset occurs. The pin goes low for the whole duration of the reset pin being low, and stays low to around when the FDCAN is initalized. This is a significant issue, as ...
Hey guys. I'm trying to use the SPI1 interface on the aforementioned nuncleo board, but no luck whatsoever.I want to transmit 2 3Byte commands to a dac device. The first one is 48,0,0 and the second one is 55,255,255. My code is: uint8_t msg_Tec[3]...
